Often it is hard to get the whole picture of new feature/improvement for each 3dsMax release. They are scattered around blog post, help documentation and release notes. Many users doesn’t even know many of their requests are already addressed if they have not carefully follow each update.
3dsMax team posted this time line. But, there are a lot more than what’s listed in that post.
So, I decided to compile all my Unofficial 3dsMax What’s New list here, which I have maintained since 3dsMax 2017. I have been a beta tester for 3dsMax for long time. This list is collected from from beta documentation and beta forum thread.
This list has 2 purposes. 1) To show how 3ds Max development really has progressed, 2) help you to find if any specific feature has been added or bug has been fixed. If so, when.
This list is divided by each release year and have all features/improvement/fixes from previous year release. For example, 3dsMax 2017 list means anything done between 3dsMax 2016 initial release and 3dsMax 2017. So, it will have all updates of PU or SP for 3dsMax 2016.
!!! From 2022.1, I’ll update this list for each PU(Product Update). I’m also adding my related video link.
Be prepare for long list!
3dsMax 2025.2
New – SVG Import/Export
- File Import
- Import SVG vector data as 3ds Max splines as individual splines or a 3ds Max group of splines.
- When multiple vector shapes are imported as splines, the splines are sorted automatically in Z depth based on the layering information contained in the SVG.
- Option to import data with Extrude modifier or Edit Poly applied
- Option to import data as a collapsed Editable Poly
- Color data of the SVG object is loaded as the object color of the spline or material(gradient data is not supported, when it is encountered the start gradient color is used)
- Automatic Multi/Sub material building. the SVGs file name would be the name of the Multi/Sub-Object Material “i.e) myFile.svg” and the sub-object materials will be named to match the specified hex color (i.e. #ffffff or #334455)
- Strokes are supported as Renderable Spline data in 3ds Max
- Automatic cleanup options (automatic weld if close spline vertex knots,cleanup of self intersecting curves)
- Max Dimension determines the size of the imported spline.
- When an unsupported piece of data is encountered during the SVG import process. The user will be notified of this unsupported data in the Listener window.
- File Export
- 3ds Max spline vector data can be exported to a SVG file.
- The exporter will check if the stack started from spline, and it will export the last spline data from the stack. Therefore, you can keep an Extrude modifier or Edit Poly modifier on the objects when you export.
- The color of the object is used to define the color of the filled-in SVG object.
- Option to use z position to handle layer ordering, and export of pivot data
- Renderable splines are exported as strokes
- Unit size is respected
New – DCM presets

3dsMax 2025
Menu Modernization
- A complete re-write of the 3ds Max menu editing system, affecting both regular menus and quad menus. This work will provide a foundation for a modern menu editing system, portable menus, and future menu work.
- The new Menu Editor allows you to easily customize 3ds Max menus and quad menus. The editor lets you add, rename or remove menu and quad menu items, create new separators and sub-menus, as well as re-order menus.
- For end users and administrators, menu customizations are now portable between 3ds Max versions (upgrade-safe), so they do not need to be re-created after each upgrade.
- Slate menu adopted the new menu system and is customizable.
- A menu definition file can be created and shipped with the Application Plugin Package, making menu creation and management much simpler for third parties. The new menu system uses a transformation approach, ensuring that menus accurately reflect the currently loaded plug-ins. In the previous system, menu customizations were not
- Developer Mode – provides additional functionality to expose their own menus or modify / add to existing ones in this mode.
- When you switch to Developer Mode, only the base menu configuration and either the selected preset or an empty preset is loaded; plug-in and user defined menus are not loaded. This simplifies the menu structure and provides a clean configuration for a developer to work with.
- For Quad menus, in Developer Mode you get an additional Quad Menu Context selection, to display only the quad menus in that context. This lets you add/rename/delete quad menus for a specific context, and more importantly, create a new quad menu context for use in your own plug-in. In non-Developer mode, Quad menus are isted for all contexts.
- Developer mode also provides access to the resource ID based localization workflow. Select “Create localization file”, and creates .mnx or .qmnx file. This creates a skeleton resource file for the configuration file, which contains the resource ID and display text for each item in the menu/quad. Once .res file is translated, placed it in the target language subdirectory for the plug-in (for example, for French, in a directory called fr-FR under the directory containing the .mnx/.qmnx file).
- New C++ API – NOTIFY_CUI_REGISTER_MENUS or NOTIFY_CUI_REGISTER_QUADMENUS callback and new ICui* classes.
- New Maxscript API – CuiMenuMgr, CuiMenu, CuiMenuItem, CuiActionMenuItem, CuiDynamicMenu, CuiQuadMenuMgr, CuiQuadMenuContext, CuiQuadMenu
Revamped Global Search

- Results display your last 5 used commands so you can repeat actions with ease.
- A new column in search shows the Item’s ‘Category’ (for example, Modifiers, Tools, MassFX, Render, and so on.)
- Filters to exclude Start with any, Contains, Metadata
- Double-click results to enact – Launch actions quickly and directly from the Search menu by double-clicking on your search results as they appear. This has the advantage that the item gets not executed right away when you do a selection in the persistent
- Contextual results – Your search results will only contain relevant items (items applicable in the current context).
- Search text highlighting can be disabled in the context menu, enabled by default.
- Resizable search bar width – From the gear icon contextual menu, you can access the Popup Width slider.
- Create a dockable window – choose Toggle Window/Popup.
- Shortcuts and extended Tooltips – Expanded results are displayed with your search.
- Settings remembered – 3ds Max will remember the last state of the tool (these settings are stored in the 3dsMax.ini file).
- Separator after the last triggered items.

- Exposed maxops.GlobalScaleTime function to scale time in the same manner as is done via ‘Re-scale Time’ in Time Configuration dialog.
- Added == and != support for MAXScript Interval values.
- getPoint() and setPoint() functions are now available for CurveControl UI control.
- Added optional arguments to windows.processPostedMessages. Default values correspond to legacy behavior. Also added additional methods that can be used instead of processPostedMessages in some cases.
- Added following options to Interface7.FindNodeFromBaseObject: handleBranching – If true, if obj is a branch of an object (such as Boolean), will continue search using the object. preferSelected – If true, if find node that is not selected, continue searching and if find node that is selected return the selected node instead. These are also exposed to MAXScript via maxOps FPS.
- Maxscript editor selection highlighting. is now case insensitive for Maxscript files.
- When opening Save dialogs in Maxscript editor, the file filter that corresponds to the file extension of the current file is automatically selected.
- MultiResIconLoader doesn’t return higher requested resolution for SVG
Viewport
- By default, the value of shadow map size limit in the viewport has been increased from 512 to 4096. This value is persist across 3ds Max sessions that the setting is saved in .ini file.
- Fixed Material dropped to an object directly from the Material list are black in the Viewport in Standard Quality.
Arnold
- MAXtoA 5.7.0.0, which introduces Arnold 7.3.0.0 core.
- Progressive dithered sampling
Arnold now supports dithered samples in progressive and adaptive rendering. Dithering brings nicer noise distributions at low AA sample counts. - GPU Renderer Overhaul
A large part of the GPU renderer was rewritten using NVIDIA OptiX 8. This allowed much faster startup times and better scaling on multiple GPUs. The following features are newly supported on GPU- multiple render sessions.
- autobump on per-face displacement shaders, previously, autobump would use the first shader applied.
- motion blur on the sphere primitive.
- shader parameter on skydome lights.
- polygons edge type in the wireframe shader.
- OSL LPE writing via debug closures.
- image shader file wrap mode.
- ID mode in utility shader.
- edgelength mode in utility shader.
- improved GPU texture filtering logic, such that there is a closer match to the CPU renderer.
- a number of fixes have been made to the GPU color management logic such that there is a closer match to the CPU renderer when rendering multiple sessions with different color management setting.
- Global light sampling in volumes – The render time speedup when using global light sampling in volumes depends on the number of lights, but even scenes with only a few lights are faster to render.
- Distance shader in reflections
- New Overlay imager allows you to decorate or tag your renders by printing text over the rendered images.
- Curves in thick mode are on average 10% faster (in some cases, more than 100% faster) and they look better in closeups.
- The toon shader now outputs AOVs for direct lighting from lights that have a label in their aov parameter.
- Imager setups can be exported and imported from arnold files (.ass, usd)
- When you add imagers, they are automatically applied in the most useful order (for example, Light Mixers go first in the list). You can still re-order them manually if necessary.
- You can select objects in the Arnold RenderView after a production render, as well as after an an interactive rendering.
- The OSL compiler in MAXtoA now loads include files from the same directories used by 3ds Max for OSL files.
- Arnold can now render MaterialX node graphs mixing standard library. DCCs loading the Arnold node definitions will benefit from the newly added UI metadata and provide a better user experience. Arnold also now uses MaterialX 1.38.8. This update includes new nodes from the MaterialX standard library.
- Per-light-group indirect AOVs no longer include emission. Emissive surfaces now only appear in the “default” light group output. When using emission in shaders, the sum of the light group AOVs will now add up to the beauty pass.
- Autobump will now be evaluated in the SSS computation with the GPU renderer when the sss_use_autobump option is enabled, this matches the behavior when rendering on CPU.
- The Intel denoiser now includes real-time denoising through NVIDIA and Intel GPU support. You can switch between Auto/CPU/GPU modes for the OIDN denoiser imager. Arnold now also provides accurate timing information for the denoiser in the log.
- now aborts if there is a license error in a batch render. The option abort_on_license_fail is now true by default, and applies to batch renders only. This means you don’t have to check rendered image sequences for watermarks. Interactive renders do not abort, and have a watermark on license fail as usual. The environment variable ARNOLD_FORCE_ABORT_ON_LICENSE_FAIL overrides this default behavior (0 = batch and interactive render with watermarks on license fail, 1 = batch and interactive abort on license fail).
- The render statistics now include the “license checkout time”, which is the time in microseconds spent on license checkout for a specific render. This is useful for diagnosing long checkout times when rendering in batch.
- Generating a .tx file (maketx, autotx, AiMakeTx) now works even if the paths to the output .tx file do not exist: Arnold now creates those paths.
- Arnold renders a few percent faster when there are many overlapping volumes.
- Improved profiling – Procedural and volume intersection times are now listed separately, instead of being included with the parent BVH. Profiling has also been added in other areas, in particular multithreaded code where helper threads were not being accounted for. This should result in higher quality statistics.
- USD
- Update to USD 23.11: The USD version was updated USD from 22.11 to 23.11 in the procedural.
- Light instances: You can now instance lights with a Point Instancer.
- Visibility and Mattes on instances in Hydra: In the Hydra Render Delegate, the Arnold visibility and matte attributes now work on instances.
- UDSZ files supported as file format: You can render usdz files with kick, and load them with the usd procedural.
- Orthographic cameras in Hydra: Orthographic Cameras are now supported in the Hydra render delegate.
- Pixel Aspect Ratio in Hydra: The Arnold Render Delegate now supports the pixelAspectRatio parameter in RenderSetting primitives
3dsMax 2024.2
New Conform Modifier
- The Conform modifier places a spline or mesh onto the surface of one or more target meshes, allowing easy adjustment of the model’s appearance without explicit shaping. It supports animated source and target meshes for added flexibility. It provides two methods, Volume and Shrink Wrap.
- Embree-based projection delivers fast performance.
- Volume
- tries to preserve the overall shape of the conform object by deforming only the bottom parts after it’s projected onto the target mesh. For example, you can use it for conforming the flange to the pipe, without deforming the top portion of the flange.
- 5 Direction controls are provided. Axis, Target Direction, Helper Origin, Vertex Normal, Closest Point.
- Shrink Wrap
- shrinks the entire conform surface around the target, like wrapping a piece of cellophane (the conform object) around another object (the target object). As a result, the volume of the conform object is not preserved.
- 3 Direction controls are provided. Axis, Target Direction, Helper Origin
- Options – provides various options such as Offset, Strength for added flexibility
- Advanced Selection Output allows passing various conform data as a soft selection channel such as Volume mode selection, Missed verts, Ray Distance, Min/Max Distance.
- Cache button allows to cache the result in the modifier for faster further modification and file loading.
Qtfied/Revamped Assign Controller rollout in Motion panel and Assign Controller dialog
- The Assign Controller rollout has been rewritten with QT and now shows the entire track tree view for the selected object.
- Navigate with the Up or Down arrow keys
- Rollout management for the Motion panel has been rewritten. now Assign Controller rollout will be open by default and retain Assign Controller rollout open and closes state between sessions
- Controllers in the Assign Controller rollout in Motion panel support the exact same right click menu that you can see in other areas of 3dsMax such as the Modify panel. This means all the new Paste options which were added in 3dsMax 2024.1, the new Assign Controller sub menus, Show in TrackView, Show in Parameter Wire Dialog are also available in the Motion panel right click menu.
- Assign Controller – You can now assign a controller from the right click sub-menu without opening Assign Controller dialog
- Improved and more stable playback performance when playing back their animation when the Motion panel is also open.
- Assign Controller dialog also has been Qtfied
Animation
- List Controller
- Append – Add a new sub controller and assign the default controller.
- Assign – opens Assign Controller dialog so the user can change/assign a new sub controller type.
- Controller and Weight spinner now supports the usual right click menu functionalities.
- Fixed a bug with List Controllers when using the Delete or Cut actions where the weight value of the remaining controllers did not update correctly
- Resolved a crash that could occur when deleting an in list controller with instances
- Track View
- Updated the intervals at which the Script Controllers. Track View performance should be 2x better.
- Enhanced the curve drawing for Script controller. Now the lines connect properly when hitting the out of range dotted lines. Also when zoomed in, the curve draws less steps.
- Resolved an issue where the Mini Curve Editor can grow slightly taller each time it is opened and closed in the 3ds Max session.
- Motion Paths
- When using a Float List controller on your Position X, Y and or Z PositionXYZ transforms, the active sub controllers tangents that are used to drive the position animation are now displayed in the viewport, and can be influenced, when using Motion Trails
- Biped
- Fixed the issue when pasting data between Xtra bones where the “Paste” and “Paste Opposite” data was not properly interpolated against the existing keys, causing a “spike” or “noise” in the animation curve. Users would need to resolve this issue through a workaround by reloading their scene, which impacts workflow and productivity.
- Reduced the number of notifications that the Biped Motion Mixer window sends. Biped’s motion mixer was always being notified when the time changes.Now it is notified only when Biped with motion mixer was used in the scene. This should help give a small performance improvement when working with the Motion Mixer.
- Updated some of the defaults on the .BIP file save dialog.
- “Save MAX Objects” is set to OFF by default
- The “Keyframe per frame” option is now set to OFF by default.
- “Save list controllers” is also now OFF by default
- The Biped List Controller UI has been updated
- CAT
- Fixed the CAT Capture Animation UI – This fix corrects issues with Auto Map, along with save and load mapping that prevented this functionality from operating as expected.
- Fixed crashes that could occur when playing back animation data on a CAT rig caused by destructive changes to the layer’s controllers or limb references. After this update, the corrupt animation data will not play.
- FIxed the crash when users detached a CAT Tail bone (or series of CAT tail bones) from the main rig. This is because detaching the CAT Tail bone breaks a dependency within the CAT rig. Now 3ds Max handles this broken dependency, allowing animators to continue to work.
- Fixed crash while loading Clips onto a CAT rig with a LookAt constraint by improving LookAt constraint code to handle CAT bone Clip data.
- Resolved a crash that could occur when saving a CAT Clip when there is no animation data in the CAT layer (or any of the CAT layers)
- When loading or double clicking a CAT Rig, the rig data will be correctly loaded at the location of the CAT Parent.
- Mirroring CAT Muscles, has been documented to address a longstanding issue where CAT mirrored muscle Pivots would cause the muscle strand to rotate around the longitudinal axes.
- Expression Controller
- “Assign to Controller” button is renamed as “Assign to Controller / Node” when you select the Vector variable to show the user can select node and get the node position.
Data Channel Modifier
- New – Maxscript Process Operator
- Allow to use Maxscript to process channels
- New – Expression Float/Point3 Process Operator
- The interface is the same as the Expression controller. If you know how to use the Expression controller, you already know how to use this. This makes the conditional and the float calculation a lot easier.
- 2 separate operators each incoming data type
- Use InValue built-in variable for the incoming channel data
- New – Presets
- Explode Elements- Explode elements from the bounding box center. You can adjust Scale op value to control the push amount.
- Map to Soft Selection – Convert map brightness value as soft selection. It is the same as Texture mode in Vol.Select modifier.
- Random Element Color – Set random uv value per elements. You can use this random number for driving drive OSL maps. For example, color or other parameter variation for tree leaves.
- Smooth Push – Smooth out normals and then push. It helps to prevent mesh overlapping when the surface is noisy. You can control the smooth amount and push amount with Smooth and Scale op.
- Resizer handle has been added to the Data Channel Modifier’s Operator Stack.
- Fixed the issue that Maxscript Input Op, theNode was returning undefined
Performance
- Vol.Select
- By Gizmo(Box, Sphere, Cylinder)/MatID/SmoothingGroup mode – 2x – 3x.
- By Mesh mode – 4x-8x(without Soft Selection) – 5x-15x(with Soft Selection)
- By Texture – 1.5x-4.5x
- Biggest fix came from ignoring soft selection for face mode. Face doesn’t have sub-object selection and Vol.Select was still calculating it. Select by mesh on half mil verts shows 15000% improvement! 0.16fps vs 42.829fps.
- Push – 50-100% faster for Mesh
- Relax – 40% faster for Mesh
- XForm – 2x – 3x faster for Mesh, 8x-9x faster for Poly
- Boolean – about 30%, the result can vary depending on geometry.
- Retopology – about 30%, the result can vary depending on geometry.
- Skin – up to 20% for the case which there are multiple skins for small/medium meshes
- Animated Splines will now properly notify 3ds Max that they have changed, this change will help to improve viewport performance.
Color Management
- Color Management in 3ds Max has exited Technology Preview.
- Color Management Preferences window now modeless and dockable so edits can be made while working in 3ds Max
- New Color Management mode: “Environment Variable”
- A new OCIO mode has been added called Environment Mode. Previously, if an OCIO Environment variable was present, and the user specified a custom path, they would clash in some situations. It was not clear which was being used. To avoid these conflicts, the new Environment Variable mode uses only the environment variable to be the config source. In turn, the Custom Config mode will never use the environment variable.
- Rules can now be customized in the UI. Users can add a new role, change the existing rule, reorder rows, remove items, and resize columns.
- Rules can now be exported and imported as standard OCIO config files
- changes can now be undone, and rules can be imported and exported as standard OCIO config files. Exporting and Importing rules are accessible through MaxScript as well. Bitmaps with input rules set to Automatic will have their rules automatically reapplied.
- The new Color Management tab in the Render Message Window shows any errors due to improper config files. It will also be logged in the specified log file.
- Users can manually enter values for HEX codes into the Color Picker.
- Spectral Conversion Colors that are specified with color (kelvin) temperature will now work with all rendering color spaces, not just sRGB.
- OCIO and OIIO updated Open Color IO has been updated to 2.2.1, and Open Image IO has been updated to 2.4.13.0 in 3ds Max 2024.2.
- Color picker HSV sliders are now more stable during transient ambiguous colors
- The Display and View Transform settings applied by the user in the Color Management OCIO modes are now saved with the scene file and do not reset to the default “Automatic” setting when the scene is reloaded.
Boolean Modifier Updates
- When a captured operand is selected, a separator bar will now display between the operands stack and the Boolean modifier to clearly denote that you are accessing a captured operand’s history.When the operand object or its modifiers are instanced the bar will be colored grey, otherwise the bar will be displayed as a teal color.
- Better coplanar face handling. The coplanar surfaces are not handled by Carve at all, rather, Max perturb the overlapping faces apart slightly, call Carve to perform the portion of the Boolean operation associated with any non-zero volumes of intersection, then finally move the faces back together, excised the area of overlap, and stitch together the resulting open edges.
- Operands’s pivot is now properly maintained. Making it easier to further manipulate the position/rotation/scale of the operand inside the Boolean modifier.
- Cut and paste operations now work with both captured operands and live operands. Paste operations must be performed in the Boolean modifier where the original cut was made.
- If you turn off Use Material, the original material ID of perands will be preserved as is.
- Improved non-manifold vertices and edges, as well as spur edges clean up. This will provide better mesh topology and more stable animation.
- Processing mesh based boolean operations is now 35% faster.
- When you are not using a Live Reference operand, the Pivot Align button will now be disabled
- OpenVDB mode supports animated parameters on operand objects.
- OpenVDB modes will generate a hollow mesh if the source is hollow.
Modeling
- Spline
- New Enable Shape Angle Constraints
- Snap Options (Tools > Grids and Snaps > Grid and Snap Settings > Options panel) lets you define your own angle constraint when creating a line object using the Create panel or the Create Line operation in the Editable Spline or Edit Spline Modifier.
- Previously, holding Shift (absolute values) or Ctrl (relative values) constrained line creation to 90 degree value changes. Now, the default of 15.0 degrees can be changed to any value or turned off altogether to customize the snapping used to constrain the line creation
- Spline End Cap Material ID
- New behavior for working with spline end caps and Material IDs has been introduced:The end caps of renderable splines now use the same Material ID as the rest of the spline. If a renderable spline is assigned a multi/sub-object material, changing the Material ID of a segment also changes the ID of its attached cap.
- Note: To take advantage of this multi/sub-object material update, edit the UseFixedRenderableEndCapMaterialID parameter in the Shapes section of the 3dsMax.ini file (C:\Users\<username>\AppData\Local\Autodesk\3dsMax\<year> – 64bit\<language>) to UseFixedRenderableEndCapMaterialID=0 and restart 3ds Max.
- New Enable Shape Angle Constraints
- Vol.Select
- Material ID, Smoothing Group ID can be animated now
- Camera Map Modifier
- added “Animated Camera” checkbox. When this is on, the map projection will be updated on each frame.
- Retopology

- The Unfold3D Pack,
- now respect the current UV selection, and the operation is only applied to the selection.
- Array modifier
- fixed “First Middle Last” type where it required a minimum of 4 elements to operate.
- LSCM(Quick Peel)
- Fixed a crash that can occur with the due to a mismatch of the data found in the geometry and in UV data
- Smart Extrude
- Resolved an issue where shading artifacts could occur when performing a non-uniform scale.
- Optimize Modifier
- Resolved a crash that could occur when it attempts to perform its operations to malformed mesh data (such as data from Sketchup).
- Symmetry modifier
- when working with older 3ds Max scenes (2021 or earlier). The modifier was not correctly utilizing the same specific version of the Symmetry code when the object was cloned. This could change the upstream topology and damage the stack result.
SME
- New nodes should respect the hide-unused preference that can be toggled by the toolbar button with no node selected.
- Slate Material Editor right click menus are now Qtfied and dark gray in the Dark Mode.
- Fixed the SME>Show Shaded/Realistic Material in Viewport button functionality.
- Restored the tooltips on buttons in SME when the focus is on the material editor window.
- Resolved situations where a docked SME would grab focus of the Alt key from the main UI preventing many common keyboard shortcuts from being available. Note that pressing the Alt key will no longer allow the user to access the SME menus when it is in a docked state.
- When the Thumbnail cache is deleted, there will not be any cache stored left and consumed by Compound nodes.
MaxFluid
- Motionfield mesh error has been fixed.
Maxscript
- Scripting Editor Selected word highlighting – Scripting editor now highlights all instances of a selected word in the editor.
- Two new commands have been added to the Scripting Editor File Menu

- GlobalScaleTime is now exposed. maxOps.GlobalScaleTime <interval>oldSegment <interval>newSegment modifyTimeline:<boolean> scaleToWholeFrames:<boolean>
- thehold.getUndoNames() and thehold.getRedoNames() – is added to access the undo/redo stack string
- getClassInstances – if you give an array of class as the argument, this function will return a dictionary with class as keys.
- The callbacks.addScript() function can now take a fileName: keyword argument that is a Python script.
- The LoadSaveAnimation interface contains new methods for getting map files and directories: getAnimFileDirectories(), getMapFiles() and getMultLoadAndMapFileFromDlg().
- The importFile(), exportFile(), and resetMaxFile() functions now take a quiet keyword argument, which is consistent with quitMax().
- Fixed ‘fileProperties.getNumProperties #contents’ to properly handle properties added before/after saving a scene file.
- ignoreSSSEState: now defaults to false for safeExecute, safeReadValue, safeReadExpr
Core
- New – Asset Tracker: Check Network Paths – this new option, enabled by default, that verifies network paths whenever the Tracker is opened or refreshed.
- Now when you save a file, unnecessary data is detected and no longer saved. Previously, every time scenes were Merged or XReffed the unnecessary data could accumulate and result in huge files and performance slowdowns.
- Empty Animation Layers, Note Tracks, or Note Keys
- Duplicate Note Track keys
- Note Tracks persisting on file load, creation, or reset.
- Provide better diagnostic info in ‘Can’t begin chunk inside Data chunk’ error message box, display error dialog at most once per file save operation.
- Fix crash when opening/saving file in folder with long name (260+ characters)
- Fixed crash when Detaching group nodes when list of nodes to detach include all the nodes in a group plus their group head.
- Fixed issues with Shift+Move cloning of nodes when selected nodes had unselected targets, and more than one copy was being made.
- Fixed a crash that could occur with the Collapse Utility
- HasBoneChildren() method has been added to prevent frequent BaseNode::NumberOfBoneChildren() call
InterOp
- Export dialog text box is pre filled with current scene file name
- The legacy SketchUp importer has been removed, and the default importer can now read SketchUp linework, including lines, arcs, polygon curves, polylines, and segmented lines. Linework is imported into 3ds Max as spline objects. See SketchUp (SKP) files.
- A new Image Quality option is now available in the SketchUp Import Settings window, improving the import speed for some SketchUp models. When enabled, distorted texture maps are redrawn. When disabled (default), import is faster, but with possible image distortion.
- FBX 2020.3.4
- Updated the “Adobe Illustrator” export to “Adobe Illustrator 8” to show the supported version
Viewport
- Now one maximized viewport is the default.
- Selection Bracket is off by default now.
- Viewport Clipping Plane is now fully exposed to MXS.
- vpSetting = NitrousGraphicsManager.GetActiveViewportSetting()
- vpSetting.ViewportClippingEnabled = true
- vpSetting.ViewportClipNear = 0.05
- vpSetting.ViewportClipFar = 0.8
- vpSetting.ResetViewportClipNearFar()
- Display Resolution settings are exposed to Maxscript
- vpSetting = NitrousGraphicsManager.GetActiveViewportSetting()
- vpSetting.TextureSizeLimit
- vpSetting.ProceduralTextureSizeLimit
- vpSetting.BackgroundTextureSizeLimit
Rendering
- Physical Camera – it will update properly when only the Zoom is animated and Specify FOV is unchecked.
- Scanline>Raytrace Message checkbox remains OFF when importing objects from scenes having this checkbox ON.
MaxToA
- MAXtoA 5.6.5.1 for Arnold 7.2.6.1.
- Improved interactivity when modifying large scenes. When editing lights or shaders in scenes with millions of instances, the time to first pixel is nearly instantaneous instead of having to wait multiple seconds. Modifying nodes during an interactive session now usually results in an update of just the modified node, not of all nodes. In scenes with many nodes, this can substantially speed up interactive node updates. In case of missing updates, you can disable this feature by setting options.enable_fast_ipr to false. An Arnold cache flush can also be used to trigger all nodes to update again.
- The efficiency of global light sampling with indirect lighting has been improved in many cases.
- Reduced numerical precision differences across CPU vendors
- Reduced noise from mesh lights in volumes
- A new kick flag -aov selects the AOV to show in the kick display window.
- If the OCIO color_manager is not given a config filename and the OCIO environment variable is not defined, Arnold will now use the builtin config. Previously it would fail with a warning and not apply any color conversions.
- You can now control whether autobump is visible on SSS for specific shapes, instead of relying on the global control, just as you can for the other autobump visibility controls. This setting has subtle effects and can increase rendering times, so enabling it only where it matters will help optimize scenes.
- Global Light Sampling (GLS) is now available with GPU rendering. Many scenes with moderate to large number of lights render 2-6x faster with GLS. Scenes that do not benefit from GLS tend to be a few percent faster or slower.
- Supports multiple outputs, such as the new outputs of the distance shader or the state shaders.
- Added out_distance and out_direction output parameters to the distance shader, which return the direction and distance to the nearest surface, respectively. The shader still returns the color-mapped result by default, which is now available as the out_rgb parameter.
- Alpha in PNG AOV output – AOVs saved to the PNG format now include an alpha channel, and you can choose between unpremultiplied and premultiplied alpha
- The Qt version of MAXtoA now matches the Qt version of 3ds Max (for example, MAXtoA for 3ds Max 2024 uses the same Qt version as 3ds Max 2025).
- Arnold RenderView (ARV) framerate improvements
- The Material Editor no longer generates tx files when it creates the swatches for a material library
- Toon shader now does a better job of detecting angle threshold silhouettes that are internal to a single object. This is most apparent in the regions between nearly parallel surfaces of an object that are at different distances to the camera.
- Improved time to first pixel (up to 10% for scenes containing many large meshes) and overall render time (up to 5% for scenes with multiple flat mesh lights).
- Multiple optimizations to make interactive renders snappier by improving the interruption rate when modifying the scene.
- Reduced noise with Global Light Sampling for surfaces near or behind flat lights (disk or quad lights).
- For interactive renders (IPR), the dependency graph is always enabled, regardless of the value of options.enable_dependency_graph. Interactive rendering updates for scene changes are improved by (and in some cases require) the dependency graph, so enforcing this setting avoids potential crashes.
- Added new boolean parameters skip_alpha and unpremult_alpha to the driver_png node. They behave in the same way as in the TIFF driver, with skip_alpha ignoring the alpha channel, and unpremult_alpha selecting either unassociated alpha (on) or associated alpha (off). Please note that PNG files with associated alpha are not supported by the PNG standard. (ARNOLD-10540)
- The OCIO color manager now supports the use of OCIO color space aliases.
- Support multipart scanline EXRs
- USD
- Now possible to render MaterialX nodes defined in third-party node definitions using the ARNOLD_MATERIALX_NODE_DEFINITIONS environment variable
- Add Arnold render status and estimated render time to viewport annotation
- Add support for camera filtermap and uv_remap

- CivilView – Fix .NET runtime exception when importing traffic simulation .FZP file
- CivilView traffic simulation (FZP) can now import PTV Vissim V11 files
USD 0.5.1
MaterialX
- MaterialX Material – This scripted material can load MaterialX files (.mtlx) into the Material Editor. Under the hood, it is actually importing the MaterialX files into a Physical Material composed of an OSL network of textures.
- MaterialX Importer – Allow to import .mtlx document as Physical material and OSL maps
- MaterialX maps – MaterialX standard library nodes are implemented ax mx_ OSL maps in Slate. This allows users to edit/author MaterialX using 3dsMax native material editors.
- MaterialX Exporter – allow to export a valid Physical material tree as MaterialX document.
- MAXScript – The MaterialX Importer and Exporter are exposed to MAXScript to allow automation and scripting.
- Integration with USD – The MaterialX plug-in comes with a Shader Writer for the 3ds Max USD Plug-in that will allow the USD export to bind references to the MaterialX files to USD Prims when exporting scenes using a MaterialX Material
Blendshape Export
- Export Morpher modifier channels as Blend Shapes in USD.
Performance Improvement
- Improved the performance of generating preview materials in the viewport for a USD Stage Object set to display materials.
- Refactored the USD Exporter code to be significantly faster at exporting complex scenes with interdependencies that are animated.
Stage Object
- Animation Frame Range now correctly accepts negative values.
- Added a button in USDStageObject to clear the current session layer.
- Not allow an empty stage mask value. If and empty string value is given, the value is automatically set to “/”.
Exporter
- USD Exporter UI to be organized into rollouts.
- A ShaderWriter is available that exports the MaterialX scripted material in the USD file as a Mtlx Reference.
- Now sets Map Channel 1 to be named “st” in meshes by default.
- The default material scope in the USD Exporter from “Materials” to “mtl” to align with Maya.
- Export non-renderable geometry objects with the Guide purpose.
- Export Group Nodes as the USD “group” kind.
- Changed the defaultPrim to “root” in the USD Exporter.
- Properly bind materials to USD GeomSubsets when the material IDs on the mesh are greater than the Multimaterial numsubs.
Exporter SDK Changes
- Added a new Python class to export materials to USD and bind to prims to help scripters and tool developers to build custom tools with materials.
- Major changes to the PrimWriter API. The PrimWriter interface now also better aligns with the ShaderWriter interface.
- Every Node->Prim translation now gets its own PrimWriter instance. Previously, a single instance was created for the entire export.
- The CanConvert() method was renamed to CanExport() and was made static. A static_assert makes sure the method exists in derived PrimWriters.
- As a consequence, the PrimWriter’s methods no longer receive a 3dsMax node as argument, instead, the node can be retrieved using PrimWriter::GetNode().
- PrimWriter::Write() is now called multiple times on animated data, for each frame that needs to be exported.
- New PrimWriter method GetValidityInterval() : Enables PrimWriter to specify the validity interval of their exported data at a certain time. From this, the exporter figures out at what frames PrimWriter::Write() needs to be called (base implementation returns the object’s validity interval).
- New header TimeUtils.h
- The TimeConfig class has been modified to ease usage, all conversions TimeValue/3dsMax frame/TimeCode are now handled from there.
- New class “ExportTime” : Represents a single time sample export configuration. I.e. the 3dsMax time value, and what USD timecode it corresponds to.
- MeshConverter::ConvertToUSDMesh() now also receives a specific time frame to convert the mesh at.
USDView
- USDView that ships with the 3ds Max USD plugin to display MaterialX.
- Added the ability to supply an explicit python.exe path (via –python-exe) to the USD tools bundled with the USD Plugin. Read RunUsdTool.bat in the bin folder of the plugin for more information.
3dsMax 2024.1
Boolean Modifier Improvements
- New caching mechanism – Boolean modifier will cache the result and save in the scene file to reduce loading time and improve stability. But, this means you can’t load 3dsMax 2024.1 max file with cache in 3dsMax 2024.To get around this problem, you can turn off the caching(SaveFinalResult) through this MaxScript command “BooleanModifierInterface.SaveFinalResult=false”. This will cause all Boolean modifiers in the scene to save WITHOUT the final result cache. Such files will load properly into any version of Boolean modifier.
- Normal support – Now fully supports smoothing groups, specified normals, and explicit normals that can exist on input boolean operands. When a mixture of smoothing groups, specified normals and explicit normals is used, all of the data in the boolean operation is converted to explicit normals.
- The UI will now display an “!” on any operands that are detected as not being watertight. Non-water tight operands in a Boolean operation have a higher degree chance of causing failures with its operand, or subsequent boolean operands.
- Support “hollow” objects.
- Resolved an issue with picking a group as an operand. It was not keeing transform correctly.
- Resolved an issue where the results of the Boolean could generate physically small elements that also had a small number of faces. This could create an issue with subsequent Boolean operations or modifiers. They are automatically removed now.
- Resolved a crash that could occur in the Boolean Modifier if the user deleted all of the operands from the Operands List.
- Resolved a crash that could occur in the Undo/Redo stack when removing operands from the Operands List in the Boolean Modifier.
- Resolved an issue the output could be incorrect when a Folder is used for OpenVDB mode.
- Fixed an issue where operand objects with animation data or animated parameters could cause 3ds Max to lockup when using the Boolean Modifiers OpenVDB mode.
- When extracting an operand from the Boolean modifier, the extracted object will now be correctly shaded as a solid object, instead of transparent.
Array Modifier Updates
- New Array by Element parameters
- First, Middle, Last – the First and Last elements specified are used only once at the beginning and the end, while the remaining elements are repeated throughout the distribution. Artists can specify the First, Middle, and Last through the element arrangement in X, Y, or Z space, or through the Clone ID of the element.
- Ordered – the cloning of elements in the array is performed in the same repeating pattern for how the elements are arranged in the mesh data, through X, Y, or Z position on the initial mesh data, or through the Clone ID of the element.
- New Phyllotaxis Distribution method parameters
- Angle Variation enables the location of each successive clone to be slightly offset along the rotation distribution.
- Seed controls the randomness at which the variation is applied to clones.
- Center By in the Arrange by Elements options is supported for Surface distribution
- Resolved an issue when using the Array Modifier’s Spline distribution type where Arrange by Elements > Random type would not randomize elements across Y and Z values.
Modeling
- Splines
- Connect open knots – When manipulating a spline that has more than one open element, you can now use Automatic Welding and Insert mode to quickly draw/continue from an open knot of one element to an open knot of another element. This workflow results in two elements that are correctly welded and connected together as one continuous element.
- Close Spline prompt – A Close Spline prompt no longer appears when using operations found in the Edit Spline modifier or Editable Spline object, or when using Automatic Weld to close an open spline element. This update lets you continue your spline creation workflow without interruption.
- New vertices respect neighboring knot types – When inserting new vertices on a spline, the knot type of the new vertex is based on the knot types of its neighboring vertices.
- If both neighboring vertices are the same knot type, like Corner, the new vertex inherits the Corner type.
- If the neighboring vertices are not the same knot type, for example one is Bezier and one is Corner, the new vertex inherits the Bezier type.
- This update affects the Edit Spline modifier and Editable Spline’s Refine, CrossInsert, and Divide operations as well as Shape Booleans, Chamfer/Fillet modifier, and the Boolean modifier.
- New Vertex Type parameter is now respected – When working with Editable Splines or the Edit Spline modifier, creating a new vertex in Create Line and Insert modes respects the selected New Vertex Type parameter (Geometry rollout)
- Improved Normalize Spline modifier so that it will better respect the incoming spline curve data as it rebuilds the spline. This fix has been versioned so that it will only apply to new applications of the Normalize Spline and not affect scenes that already utilize the modifier.
- Smart Extrude
- When Smart Extrude, the faces that are not planar to previously existing geometry, will be automatically smoothed if they are within 30 degrees of tolerance from one another.
- When performing a Smart Extrude with Editable Poly objects. 3ds Max will attempt to utilize the existing normals of neighboring faces when the extrusion is co-planar.
- Explicit normal
- Explicit normal preservation – Turn to Poly, Vol. Select, Mesh Select, MaterialByElement, UVW Mapping Clear, UVW Mapping Add and Select By Channel modifiers on a Mesh class object.
- Explicit Normals are now supported on a Mesh class object when using the Maxscript call modifiersEdit_Normals.EditNormalsMod.MakeExplicit ()
- A bug with MNFace::Insert was fixed which could affect Specified Normals when you are adding normals due to a topology change.
- Path Deform
- If the Path Deform spline path is smaller than the size of the Object that is being deformed, the object was disappearing. This is fixed.
- Volume Select
- Fixed an issue where the OSL Map that it uses would not display in the viewport if the Material Editor was not open
- Shell
- Fixed an issue with making non-manifold UV data.
Performance
- VertexPaint – various optimization provide much faster performance for highres mesh painting, For example, unaltered geometry and topology channels would not be evaluated. The world space bounding box is cached while painting. Brush falloff curve now utilizes a precomputed lookup table.
- FFD 2x2x2, FFD 3x3x3, FFD 4x4x4, FFD(box), FFD(box) Space Wrap is now up to 2x faster.
- Adding keys for the Bezier controllers and the TCB Rotation controller has been optimized – All Bezier controllers are now up to 30x faster. TBC rotation controller is up to 4.5x faster.
User-defined defaults
- Set as New Default – takes the current parameter value and sets it as default. This change persists not only for the current session, but remains the default until you change or reset it. You can return to this new default value with the existing Use Default (Ctrl + right-click) that is already in the right-click menu.
- Restore to Factory Default – to return the value to what shipped with 3ds Max.
Animation
- Animation Controller
- Copy and Paste Animation in right-click menu no longer require controllers to be pre-assigned. 3ds Max now assigns the default controller automatically while copying.
- The right-click Copy/Paste menu will show the parameter name that you are copying and pasting.
- Copy, and then Paste – Copy (or Paste – Instance) directly from the parameter in the main UI to controllers in the Track View
- Assign Controller and Reset to Default Control options have been added to the right-click menu.
- Character Studio
- Resolved a crash that can occur when parenting an Biped Xtra Bone to a Biped Nub object. Xtras are now blocked from being parented to the nub objects
- Fixed a crash that could occur when animating a part of the Biped that uses an IK Target and your active time range does not start at frame 0.
- When using the Biped Dope Sheet, a crash could occur when extending or sliding a footstep past the last footstep; as well as fixed a regression where sliding, extending footsteps were causing crashes.
- Fixed an issue where when the user is driving the vertex deformation of the Skin Modifier with an animated Spline object instead of bones The object would not update properly in the viewport when the frame changes unless the object was selected and the modify command panel was active with the Skin modifier selected. It still required the listed selection workaround.
- Resolved an issue with the Morpher modifier where it was using the modifier selection instead of the channel selection. This could result in scenes created in previous versions of 3ds Max having their Morpher data not playback as expected.
- Fixed an issue with the Offset Controller where it was not updating the transform matrix caching after it was applied
- Resolved a crash that could occur when objects or controllers with note tracks in the curve editor or dope sheet were cloned and then the user attempts to undo the clone action.
- Resolved a crash when using a Link Constraint and its linkParams parameter.
- Resolved a crash that could occur when attempting to undo a “Delete Selected Animation” command that was applied to Biped objects, Bones, Link Constraints, and other 3ds Max objects.
- Fixed an issue with the Curve Editor where the Isolate Curve button was not properly updating it’s state when active.

- Colors shown in the color picker now match the colors shown in the UI allowing easier customization of UI colors.
- Viewport Canvas settings can be saved and loaded. Fixed MXS exception.
Arnold/MaxToA
- MAXtoA 5.6.2.0 for Arnold 7.2.1.1
- AOV Wizard: The updated AOV manager consolidates the two existing “Wizard” functionalities into a single streamlined AOV Wizard experience. You can now set up the most useful set of AOVs with a few clicks.

3dsMax 2024
New OCIO v2 based Color Management
- Until 2024 3ds max has assumed color spaces with sRGB primaries and provided color management via de-gamma/re-gamma workflow. That sRGB assumption removed. Also color processing pathways, including few API exposed areas were modernized to make sure color fidelity is retained throughout the system. Old gamma manager and colorcorrection manager classes are being deprecated, new ColorPipelineMgr will provide unified interface for both the legacy gamma workflow and OCIO-based modern color management workflow.
- The highest priority was not breaking the existing workflows or existing scenes while providing the brand-new workflow. Default is Gamma Workflow. Therefore, if you don’t do anything. Everything should work exactly same as before. The previous workflow is provided as an optional mode.
- “Unmanaged” mode will give you the same behavior as the “Enable Gamma/LUT Correction” unchecked.
- “Gamma Workflow” mode will give you the same behavior as the “Enable Gamma/LUT Correction” checked.
- Color Management Preferences(Previously Gamma and LUT) has two new OpenColorIO v2.2 based color management mode
- OCIO (Technology Preview) – 3ds Max Default
- OCIO (Technology Preview) – Custom Config File
- Bitmaps now have associated color spaces and GetLinearPixels() call will not only linearize the pixels but will also convert the colors into the rendering color space on the fly.
- Bitmap Image Selector, OSL Bitmaps, Arnold Image map support color spaces conversion fromOCIO config file
- Rendering color space support including ACEScg
- Display/VIew color space support for Viewport, Render Frame Window, Material Editor, Color Picker, Color Swatch, Image File Viewer and Arnold Render View
- Scene Linear Exposure and Post Display Gamma spinner in Render Frame Window and Image Viewer for investigating the image
- In the Render Frame Window’s right-click window information display has been expanded. You can see the assigned color space (also visible in the window title). Selected pixel values will now be displayed in 3 different color spaces: the image color space, the rendering color space, and the display color space.
- Render Frame Window has also received some speed boost, panning and zooming should be much smoother compared to 2023.
- Viewports are properly color managed in the DirectX mode, GPU rendering is also performed in the specified rendering color space and the result will be displayed using the selected display/view transform pair.
- Active Viewport Settings/Color Management Tab allows every viewport may have its own display/view transform or can use the default Display/View transform (Automatic).
- Image File Save supports No Conversion, Color Space Conversion and View/Display Transform from OCIO config file
- MaxToA now pass on all color management information from 3ds Max to Arnold for rendering by handing over the entire OCIO configuration for rendering.
- Improved Color Swatch displays colors in 2 different color spaces, Scene-referred linear space (Rendering space) and Display-referred space Values are displayed in 3 different number formats, unbounded floating point, unsigned 8-bit integer (0..255), Hex web colors
- New utility called Color Converter is available in the Utilities>More list, and as a sample in the MaxSDK. This utility will showcase the Color Management API
- System for tagging color parameters for their use case (UI colors, surface colors, light colors, non-color data, etc) to exclude those colors from color management
- Full Maxscript exposure through ColorPipelineMgr interface
- Allow to lock custom OCIO mode with Maxscript. The UI will reflect the locked state through an icon.
- The Bitmap object has several new read-only attributes added as part of the new Color Management support, and the openBitmap() method has a new optional colorSpace: keyword parameter. There is are also new validateColorSpace() and SetOutputColorConversion() methods for bitmaps.
New Boolean modifier
- New MNMesh2 powered modifier-based workflow
- 7 Boolean operation types including 2 New boolean operations
- OpenVDB based volume boolean mode enables simple and easy mesh <> volume workflow. Combined with Retopology modifier, it opens a lot of new posibilities.
- Improved support for booleans across multiple elements. For example, when performing a Split or Inset operation on the Boolean Modifier, these operations will be processed one at a time on each element.
- Capture / Live Reference mode Capture mode will embed operands into the main object.
- Operator Manipulator allows manipulating operand’s transform inside of Boolean modifier using the color-coded manipulator.
- ShIft-drag to clone operand inside of Boolean.
- Folder support
- Picking up a Group will automatically setup folders(CUrrently only works for Live Reference mode)
- Use Material – preserves material on the operand objects while boolean. This will combine all operand’s material and build a multi/sub material automatically.
- Create Object from Result – creates a new object based on the boolean result up to the selected Operand.
- Paste to new Boolean Modifier – allow to paste a cut operand into another boolean modifier.
- Create shape from seam allow to creat spline object from boolean seam.
- Disable interactive updates – When active the results of the boolean operation will only be processed when the transform operation is complete.
- Create rollout > Create Objects enables the capability to export the elements of the current state of the Boolean results as separate mesh nodes. Making it easier to produce variants for subsequent modeling workflow as well as data for simulations and other purposes while still retaining the original boolean modifier source.
- By nature, boolean is prone to generate bad topology. The boolean modifier has a lot of built-in clean-up code for input/output topology. This also allows more stable Boolean operations.
New Material Switcher material
- Allow to switch among sub materials up to 9999
- Sort by ID, Name or Material Name
- Lock button allows to Insert or Delete a sub material without changing index
New Transform List controller and List controller improvement

- Search filter
- Scroll bar size Preference option
Animation
- CAT
- Resolved an issue with CAT when the Display Layer Transform Gizmo option was active that would result in the Motion Command Panel continuously redrawing, creating a flickering affect. This redraw affected viewport performance and made it almost impossible to move keys on the Time Slider.
- Resolved an issue where if a user adds a Vertex Paint modifier to the CAT Bones, paints vertex colors, and then chooses “Collapse To” from the modifier stack, 3ds Max would crash.
- Character Studio
- Resolved a crash that would occur with Biped when deleting Xtra Bones from the Biped Structure in Figure Mode, and then undo the action and attempt to restore the Xtra Bones to your Bip rig.
- Resolved a crash that would occur with Biped when attempting to Undo after deleting Xtra Bones from the Biped Structure while in Figure Mode.

- Fixed a crash that can occur when baking keys with MassFX and then attempting to undo the action.
- When opening the Motion Capture utility in the command panel for the first time, if there is no motion capture controller assigned to the object, this utility will no longer pop-up an error window warning the user about needing to assign the proper controller. This message is now properly displayed in the 3ds Max status area of the UI where the user knows to look for messages.
- Fixed when copying an object with attachment constraint that has its “Align to Surface” Checkbox disabled, the newly cloned/copied object will now also have its “Align to Surface” in the same disabled state.
Array v2
- New Phyllotaxis Distribution Method – clones in a spiral pattern, distributing clones from the center out. The resulting spiral mimics organic distribution patterns that are found in nature, like leaves on a plant or seeds in the head of a sunflower.
- New Material ID options
- Assignment methods – Ordered, First Middle Last
- N TImes – allow repeat material id assignment
- Phase animation
- New Progressive Transform option for the Radial, Spline, and Phyllotaxis distribution types enables the artist to alter the transform data to progressively change from first to last mesh distribution.
- Transform Before Projection – allow to transform the position of the clone prior to them being projected to a surface using the spline distribution. The typical use case is that of a set of fence posts on uneven terrain. The customer wants to be able to randomize the position of the post while still ensuring that they are set into the ground and don’t move off of the terrain.
- Create Objects now keeps hidden edges for mesh source.
Modeling
- The improved triangular algorithm which was introduced in 2023.1 has been improved further. Now also used in Edit Poly modifier. This will results that minimizes concavity when performed on non-planar topology.

- When you close Insert on spline, it will correctly snap to target end point
- Fixed Optimize spline breaks Mat Id
- Retopology
- Reform 14.0.1 – fixes some previous failure cases, and improves the quad topology in some others.
- Fixed a data loss issue when you navigate under the Retopology modifier in the stack, make some sort of geometric or topological change, and then save without recomputing retopology. Previously, this would “lose” the remeshed and retopologized meshes in the saved file; now, they are properly retained.
- Selected Edges Auto Edge constraint previously was not honored when the Preprocess Mesh option was active; now, this is correctly handled.
- Symmetry modifier default axis changed to X.
- Normalize Spline Modifier will preserve MatID
- Fixed an issue with the UVW Map modifier where it was incorrectly clearing the explicit normals of a Mesh.

Maxscript/Python
- Complete MXS exposure for CreatePreview()
- instead of initializing preset/visualstyle/edgedface/textures options hard-coded (e.g., High-Quality for preset), init them using the active viewport’s options (e.g., use UserDefined preset if the current viewport use a customized preset)
- add missing maxscript exposure – dspCamViewName:true autoPlay:true vpPreset:#userdefined vpStyle:#defaultshading vpEdgedFaces:true vpTextures:false
- Allow controller argument to setPropertyController to be ‘undefined’ for removing controller, ditto setting property via <object>.<property>.controller.
- The EmptyModifier no longer converts the incoming object to a mesh on the stack.

- The windows struct has several new functions: windows.isWindow(), windows.isWindowVisible(),windows.showWindow(), windows.getWindowPlacement(), windows.setWindowPlacement(), windows.setFocus(), windows.setForegroundWindow(), windorootscene
- ws.getWindowLong(), and windows.setWindowLong().
- All windows struct functions that take a HWND argument for the window to operate on now can take a RolloutFloater, Rollout, or the main 3ds Max window (specified by the name #max), making it easier to operate on these types of windows without having to query their window handle first.
- The new errTracebackDisabled system global specifies whether to disable error tracebacks in the listener window. Intended for testing / internal use only.
- The <ChangeHandler> value has a new .enabled property that allows you specify whether the handler is enabled. This allows you to disable handlers without having to de-register or delete them.
- The spinner UI control has a new property autoscale:<boolean>, and these existing creation keyword parameters are now exposed as properties that can be accessed at runtime: scale and type.
- Read-only ‘superClassID’ property to MAXSuperClass has been added.
- Added system global: errTracebackDisabled – bool Setting errTracebackDisabled immediately before running an expression that throws a runtime error controls whether an error traceback is sent to listener. This is primarily used when writing unit tests.
- Fixed issue that rollouts that are defined as structure members can now access other members of the structure instance. Rollouts that are defined as local variables in functions defined in a structure still cannot access other members of the structure instance.
- Added protection when recursively enumerating the SubAnims of objects to prevent infinite recursion due to a SubAnim under a node pointing to the parent node of the node.
- Fixed issue where memory corruption could occur in a certain case when updating scripted plugins using new plugin definition.

- Added Context construct to the USD Exporter SDK. This allows USD Plugin developers to better control the export of their plugin data and help simplify the exporter UI for users.
- Added self.GetNodesToPrims() to PrimWriters that will get a map of prims made from nodes in the scene. Helpful for writing associations to prims created from other nodes in the scene.
- Added the .version property to the maxUsd Python module to know the USD plugin version.
- Exporter
- Support for Skin to be exported to USDSkel.
- The items in the plugin configuration combobox are now checkable. Multiple elements can be selected or none of them can be selected.
- Added an option in the USD Exporter to not nest Gprims. This option will now be on by default and makes the USD created from 3ds Max conform more to the general USD guidelines.
- Updated to merge Plugin-Configuration settings and user-settings, allowing USD Preview Surface materials to be written alongside context-driven materials, such as Vray Materials (when an appropriate version of Vray is installed).
- Updated the USD Exporter to comply with USD standards for not nesting shader nodes.
- Fixed missing sourceColorSpace, scale and bias settings for Normal maps in the USD Exporter that was casing incorrect normals display in USD. Also, for non-Normal maps, sourceColorSpace will be set to “raw”.
- Updated USD Exporter default primvar name of UV channel 1 from “st” to “st0”. This is a temporary fix to deal with a MaxToA issue introduced with the change to USD 22.11.

Abstract – Cross Contour, Abstract – Cross Contour 2, Abstract – Marbley, Abstract – Portal To Hell, Abstract – Shooting Stars, Abstract – Starry Night, Caustics – Bright, Caustics – Dark, Caustics – Fractals, Caustics – Oily, Caustics – Puddle, Cells, Cells – Mask, Defaults, Fabric – Pinholes, Fabric – Plastic Bumps, Fabric – Stretch, Membrane, Oil – Mask, Oil – Shiny, Plasma, Smoke – Gooey, Smoke – Puffs, Smoke – Rings, Splotches – Bright, Splotches – Cartoony, Splotches – Glassy, Splotches – Tearing
- UVW Randomizer 3D/2Dapplies a random Scale, Offset and Rotation to UVW data. These can be driven by seed for per-object randomness for each effect.The 2d one defaults to UV Channel 1 and only does 2d rotations. The 3d one defaults to object space and does full 3d rotations.
Performance
- Poly to Mesh conversions performance has been improved across 3dsMax. Modifiers that need to convert data from Poly to Mesh can see up to a 40% speed improvement, viewport performance can benefit up to 35%, and users can see a small boost in performance when their scene data is sent to an offline renderer such as Arnold.
Animation
- Attachment constraint – It would always set a key at frame zero when using Auto Key mode. Now a key is either set at the current frame or the default animation frame if that is enabled in the preferences
- CAT
- Resolved a lockup that could occur when the animator attempts to rotate the limb bones of the CAT Rig when 3ds Max Motion Paths is enabled.
- Using the maxscript command “$.TMController.CATParent” users can check if a CAT bone in their scene has a valid parent and CAT Parent bone. If the value returned is “undefined”, the CAT bone can be safely removed from the scene without breaking the CAT rig.
- ParticleFlow – When using a PFlow Birth Texture operator, Physical materials are now properly supported to work with the bitmap data of the material and not the luminance value of the shader at each pixel to determine where a particle can emit.

- Fixed a crash produced when baking textures through Maxscript.
- In 2023.2, a fix was made to prevent wiring of parameters that did not have the same controller class to prevent memory corruption. But doing this prevented wiring Point3 parameters to PRS controller’s Position and Scale tracks. Now explicit handling of Position and Scale controller types to the Point3 wire controller class is added.
3dsMax USD 0.3
- USD Stage Node is now supported in 3ds Max. Reference a USD stage directly into 3ds Max to create a scene with USD assets from an existing file. Using this workflow, you can view and render USD data directly in 3ds Max.
- File > Reference > USD Stage…. Create Panel > Geometry > USD > USD Stage
- Stage Masking support
- Full access to working with in-memory stage data. You can build Python, C++ and MAXScript tools to interact with the data inside a USD Stage Object. The stage has a read-only property called CacheId that can be used to access the stage from a global USD cache. Using this you can directly manipulate and interact with USD data (moving prims, changing visibility, etc.)
- USD Stage fallback rendering mode allows rendering USD Stage even when renderers do not support accessing a USD stage directly.
- UsdPreviewSurface material support using texture transforms (UsdTransform2d) and texture wrap modes.
- Assign USD Materials button to build a Multi/Sub material for fallback rendering mode. Users can override any parameters of the material tree.

- Resolved a crash that can occur when copy and pasting the Skin modifier to other objects in your 3ds Max scene.
- Skin
- Fixed an issue with the Skin modifier where the bone influence heat map of Edit Envelope was overwriting the vertex color data for the object that it was applied to.
- DeltaMush
- “The Delta Mush operator found in the Data Channel Modifier has been updated to use an improved algorithm that will provide an enhanced symmetrical result across the mesh.
- A “Use Legacy Compute” checkbox is now found on the Delta Mush UI. When loading older scene files, this checkbox will be active. When creating scenes from scratch in 2023.2 (or adding the Delta Mush operator for the first time to a new Data Channel modifier), this box will be unchecked.
- When switching the “Use Legacy Compute” checkbox, the user should do this at the “neutral” or “rest” pose time, because capturing the rest pose stores information critical to the Delta Mush functionality
Performance
- MeshSmooth Various operations within Poly have been updated to provide improved performance when checking for and processing data without bad mesh data (which can be cleaned with the Mesh Cleaner modifier). It will improve NURMS performance in Mesh Smooth, Edit and Editable Mesh, and Edit and Editable Poly
- Skipped material’s evaluation under Display Color>Shaded: Object Color mode
- Removed the baking of textures/procedurals when Viewport Configuration>Display Performance>Textures is unchecked, to greatly improve the loading time of scenes with this setting turned off.

- Environment variable ADSK_3DSMAX_BUFFEREDFILE_BUFFERSIZE and 3dsmax.ini setting Performance / BufferedFileBufferSize for a file buffer size to use when loading or saving most types of bitmap files. If neither are specified, a buffer size of 256KB is used.
- In Parameter Wiring dialog, added testing to ensure selected parameters use same controller type. If not, the direction buttons are disabled and their tooltip says the parameter controllers are incompatible. If attempting to wire via maxscript, the wiring will fail.
- in some cases of scene file corruption, attempting to merge nodes from the scene would fail when the first instance of corrupted data was found. Now when the scene contains the corrupted data “Select Nodes With Corrupted Data” button will appear at the bottom right corner. User can check the problematic node with this and revert the selection to avoid merging if the objects.
Maxscript
- The Collapse interface exposes the functionality of the Collapse Utility.

- Python binding error message – When Arnold cannot be loaded by the python bindings, we now output the original exception error message instead of just the cryptic “Could not find libai”.
- USD Enhancements
- Support dataWindowNDC – when the render settings primitive defines the attribute dataWindowNDC, it now renders accordingly in both Hydra and the USD reader.
- Cryptomatte in Hydra – When rendering final frames with Hydra, the cryptomatte metadatas are set in the output image
- Render products with no productName – When AOVs are defined through a render product prim that doesn’t have any product name, they now render to the same filename as the beauty image.
- Instances optimizations in the procedural – When using instances, the usd procedural now relies on a usdStageCache to represent the instance prototypes, instead of re-loading the usd files on disk for each prototype.
- Pinned curves – Curves pinning is now supported in hydra and in the procedural
3dsMax 2023.1
Spline Extrude
- New SHIFT+Extrude for Editable Spline and Edit Spline modifier
- In a Segment sub-object component mode, holding SHIFT+LMB (Drag) while performing a Move, Rotate, or Scale transform action will Extrude the segments based on the transform action, creating new supporting Vertex and Segments.
- SHIFT+LMB (Drag) on the start or end points of an open spline on the Vertex sub-object component will enable the user to draw new segments and further extend the spline.
- Cloning of Spline Vertices or Segments can now be performed with CTRL+SHIFT+LMB (Drag)
- When the user changes a Spline Vertex type to Smooth, Bezier, or Bezier Corner, 3ds Max will also automatically adjust the adjacent Spline Segments will also be adjusted to a Curve type (if they are not already defined this way). This change will result in a more immediate update and visual representation of the data instead of the Segments being locked as linear or straight
Triangulation
- New Triangulation algorithm prevents inverted or collapsed triangles, generates more regular fewer long, thin triangles and handles non-planar faces better. Chamfer and SmartExtrude utilize this new algorithm. It will eventually be deployed more broadly.
- You can also use this new algorithm for Editable Poly’s Retriangulate operation by using MXS command. $.enableEnhancedRetriangulation = true
Progress bar update
- The Progress bar progress will be displayed in the 3ds Max icon. Any feature that uses the status bar progress bar will be benefited from this update such as Create Preview or Maxscript.
- File IO operations(Load, Save, Autobackup) support progress bar.
Performance
- Skin improved data management that is performed by the Skin modifier. Users will see an improvement of roughly 30%-90% when “Edit Envelopes” is not active.
- Morpher improved animation performance through numerous optimizations with threading, caching, improved explicit normals acceleration, channel management, and memory management. Users should see anywhere from a 4x to 40x improvement to their Morpher Modifier.
- TurboSmooth threading and improved memory management provides roughly 2x performance improvement
- Alembic has been updated to 1.8.3. This update improves file load and read performance improvement which can provide between 25 and 65% performance gains
- Point helper values are cached with a validity interval. It provides about 10% evaluation performance improvement.
- Viewport background playback Improved playback speed with animated background if the source image is in sRGB or gamma 2.2. It is 2x-3x faster.
- Asset file loading Increased buffer size when reading/writing image files from 4KB to 256KB for most image file formats. This results in improved performance when reading/writing image files over a network
- Merge dialog Improved performance of Merge dialog when dealing with large number of nodes.
- Selecting/moving/rotating object sub-elements in Mikkt mode greatly improved
Isolate selection updates
- Zoom Extents On Isolate (ZEOI) is now persistent from session to session (in 3ds Max.ini).
- Default value of ZEOI is set to off, means do not zoom extents on isolation.
- ZEOI is now shown in the quad menus by default, below Isolate and End Isolate (Note: menu reset is needed if doing an upgrade install).
- The Isolate Selection button in the status bar is now a flyout (caret) button with two states.
- Hotkey improvements (default: Alt+Q). If in isolation mode and the key is pressed again
- If nothing is selected: end isolate (feels like a toggle)
- If selection is the same as last isolated objects: end isolate (feels like a toggle)
- Else Isolate new selection (feels like a new isolate)
Modeling
- Vertex Paint modifier A new button is available called “Capture” which copies all of the existing vertex colors that exist under the current Vertex Paint modifier into this level. This will allow you to blur and work with the existing data easier.
- Unfold3D Optimize Active sub-object selection will be used for the Relax operation.
- Smart Extrude Uses the improved triangulation and handles concave corners better
- Occlude Selected Crash fixed when selecting subobjects with a “Right- >Left=>Crossing” selection option
Core
- ADSK_3DSMAX_COMPRESSEDFILE_TEMP_FOLDER that can be used to specify a folder where to create the temporary files used when loading and saving compressed scene files. These files hold the uncompressed content. When not specified, the folder specified by the TMP environment variable is used.
- Missing plugins dialog has been removed. The Scene Converter provides the same missing plugin information and allow to remove them selectively, The missing plugin information is now also listed in Max.log.
- In the Save dialog for saving a material library, the ‘Save as type:’ dropdown will contain contents similar to the max scene Save dialog. It will contain entries for the current max version (unnumbered) and the previous 3 versions (numbered).
- The Object Rename tool now renumbers objects using three digits instead of two.
InterOp

- Asset Tracker Constantly Loses Previous Position/Size Fixed issue with Asset Tracker losing previous position and size if 3ds Max was opened and then closed without the Asset Tracker dialog being displayed
- Flashing UI while executing reduceKeys fixed MAXScript command “reduceKeys” no longer spawns MAXScript listener upon completion
Animation
- Scaled Keys Lose Curve Fidelity Corrected an issue where the tangents for keyframes would not update properly as the keys are scaled down significantly. Now when keyframes are scaled down the curves retain their correct information with minimal distortion from the original value.
- Controllers don’t preserved the original transform information of the objects when created with Maxscript fixed This affected the Animation > Constraints menu actions
- Fixed an issue with the names of the TCB controllers found in the Animation toolbar menu Instead of being listed as Quaternion TCB these controllers are now descriptively (and correctly) named TCB Position, TCB Rotation, and TCB Scale
Rendering
- Physical Material: Maps can be drag-and-dropped onto a slot and have a bitmap node created.
- Enabled the output selector when dragging & dropping multi-output maps directly on a Physical material map input.
- Active Shade refreshes correctly when Hide by Category is enabled/disbled
- Random index by Number/Color has been updated to provide better randomization for a small range. Also it handles integer inputs better.
Viewport
- Perspective Match improved with a new switch called “Allow Distorted View”. When ON, this switch allows the final view to be distorted, a non-uniform camera could be created in these cases. Note that some applications will not fully support non-uniformed scaled cameras.
- Back Face Lines color customization fix This color is re-connected. So, now you can control the darker edge color. It will get 0.5 of assigned color for the darker edge. When you use the light scheme, bg color and darker edge color happen to be the same. Now you can adjust this color to solve the issue.
- The viewport setting “Improve Quality Progressively” is saved with the scene.
Maxscript
- support for saving material libraries to previous versions of 3ds Max. ‘saveAsVersion’ support added to saveTempMaterialLibrary, saveMaterialLibrary, sme.SaveMtlLib and sme.SaveMtlLibAs FPS methods.
- The optional skipXRefs parameter for loadMaxFile allows you to disable scene and object XRefs during scene load to speed up file loading. You can load XRefs later by selecting the reference and updating it.
- When the following render settings are changed via MAXScript : RenderWidth, RenderHeight, Image aspect ratio, Image aspect ratio lock, Pixel aspect ratio, Pixel aspect ratio lock, Aperture width. The render format is now automatically changed to “Custom”
- ‘this’ structure instance lost going through createDialog Fixed issue that rollouts that are defined as structure members can now access other members of the structure instance. Rollouts that are defined as local variables in functions defined in a structure still cannot access other members of the structure instance.
- AssetManager Keeps Previous Scene Assets in Memory Fixed issue with BatchRenderManager not properly releasing assets when deleted
- The File/New All command immediately removes the selection set names from the previous scene.
Python
- PYTHONPATH support was restored (removed in 2022.2_Update, back in 2023) Several studios commented recently that the lack of support for the PYTHONPATH env var creates disruptions in their pipelines, they have to understand how to patch their pipeline scripts.
3dsMax 2023
glTF Export
- New glTF Material
- Exporting Static Mesh Geometry with BitmapTexture
- In BitmapTexture, the Tiling, Offset and W_Angle are exported using the KHR_texture_transform extension if Offsets or W Angle are non-zero or Tiling is non-one
- Textures are automatically packed together into proper channels once exported
- Export limited support for Physical Material
- Accurate viewport display of the glTF Material in most cases (some, like volume, require Active Shade using Arnold)
Snap Working Pivot
- Quick Pivot – align working pivot to the nearest sub-object with one key
- Place Working Pivot – When active a gizmo will be displayed to aid you in the placement of the pivot on your vertex, edge(center), or face (center)
- Selection Pivot – With an active component selection, this option will place the pivot on the center of the selection. The pivot should be oriented in the averaged direction of the selection.
- Align Working Pivot – When enabled, this mode allows the user to adjust the orientation of the working pivot. You also have the optional ability to lock a particular axis, so that the axis stays aligned to where it is currently placed, by double clicking on the circular gizmo at the end of the working pivot when this mode is active.
- Reset Working Pivot – Resets the working PivotAlign Pivot to Working Pivot Adjusts the Pivot to match the current position and orientation of the Working Pivot
- Place Pivot Bounding Box – This adds an optional bounding box that fits the object or selection. The bounding box has 24 additional points that allow the user to snap the working pivot to a selected point.
- Create Grid From Working Pivot – Create a new Grid Object aligned to the position and orientation of the Working Pivot.
- Create Point From Working Pivot – Create a new point helper in your scene aligned to position and orientation of the active Working Pivot.
- Snap Pivot Toolbar Tools – Tool > Snap Working Pivot Tools menu, toolbar and quad menu has been added.
Retopology
- Preprocess
- Turning on this option will build an intermediary Remesh state based on the target quad count using the proprietary ReForm pre-processing algorithm. This provides the following benefits.
- This evenly-sized triangle mesh makes ReForm processing significantly faster(1000%-2000% faster in my test).
- Allow you to get a really low target result. Without preprocessing, ReForm simply refuses to respect a very low target.EIther it would fail or give a lot more polygons.
- The interim remesh provides a very simulation friendly topology.
- Data Preservation All data corresponding to the selected Auto Edge options is now propagated to both the remeshed and retopologized meshes; for instance, if you select the map seam and material ID Auto Edge options, then the select map channel and the material IDs will be propagated.
- The “Output” parameters on the Retopology modifier will now control which set of mesh data is utilized and pushed up the modifier stack. Allowing the artist to send the original mesh, the retopologized quad mesh, or the triangulated preprocessing mesh (if generated).
Autobackup Improvement
- Autobackup Toolbar
- Right clicking the Enable/Disable Autobackup button in the Autobackup Toolbar now opens the Files tab of the Preferences dialog so that users can easily edit the Autobackup settings
- New Autobackup Time Interval progress indicator
- Enable\disable Autobackup, Autobackup Interval progress indicator\counter, Reset Timer
- Autobackup commands can be assigned hotkeys
- Autobackup Settings
- Added option to toggle displaying the number in the toolbar (“Display Countdown Value”)
- Compress on Autobackup (disabled by default) – allows files to be saved compressed and backups to be un-compressed (for maximum speed). Also exposed to Maxscript: autosave.Compress
- Prepend Scene Name (disabled by default) – when used, helps minimize overrides of Autobackup files by simultaneous Max ssessions. Also exposed to Maxscript: autosave.prependscenename
- Handling of backup files by simultaneous Max sessions has been improved: The “number of backup files” (N) setting represents the number of total backup files given a the backup naming convention used by Max sessions. If multiple sessions use “Autobackup” as name, they will preserve existent Autobackup files until N is reached, then start replacing the oldest file. This is an improvement over Max 2022, where two simultaneous sessions would each try to backup to Autobackup01, overwriting each other’s backup. Now, session1 of Max creates Autobackup01, session2 of Max creates Autobackup02 etc. When AutobackupN+1 needs to be created, the oldest Autobackup file is replaced.
- Autobackup timer pause can happen when <20 seconds left, and it can be changed with autosave.finalCountdownInterval
- Default timer interval changed from 5 min to 15 min
- Default number of backup files changed from 3 to 10
- Autobackup does not interrupt user activity
- Autobackup timer starts only when the scene is dirty and stops if the scene is no longer dirty. To support this feature, many actions that were making the scene dirty unnecessarily have been fixed include opening RTT, toggling Export dialog.
- Autobackup will not kick in during MassFX simulation, Fluid Simulation, Cloth, Texture Baking and any actions that use the main UI progress bar.
- Animation Playback will pause the timer when 20 seconds left
- Modal dialogs prevent Autobackup. The timer will keep counting down, but it will pause at 10 seconds if a modal dialog is displayed
- Mouse down+drag, most right click menus and menus in the main toolbar or any mouse capture such as during object creation will pause the timer (when 20 seconds remaining)
- Editing in fields prevents Autobackup from kicking in (except in a few places such as MCG nodes)
- Autobackup wouldn’t steal focus from MXS editor
- Reduced the frequency with which the Bailout Manager checks if the Escape key is pressed from 0.5 seconds to 1 second
- Backup File Menu
- File > Autobackup > Autobackup Now – allows you to save a backup right away
- File > Autobackup > Open Autobackup Location – allow to open autobackup folder.
- Scripting and SDK
- Added two functions to MAXscript to allow users to save their Autobackup settings to the 3dsmax.ini file or load them from the 3dsmax.ini file. autosave.saveSettings() autosave.loadSettings()
- C++ and Scripting APIs for preventing Autobackup from kicking in. These should be used by 3rd party plugins and scripts GetAutoBackupInterface()->SetTempDisable(true|false); autosave.tempDisable = true|false
Compress Save Performance
- New zstandard compression engine
- When saving a compressed file, compress the data for each entity immediately after its data is generated.
- Great performance improvement when compression is on(500% to 2500% in my test).
- Saving with compression on will only take 10-15% longer than with off in my test case. Before this improvement, turning on compression on used to be 400-600% slower than off.
- In many cases, now saving with compression on in 3dsMax 2023 is even faster than compression off in an older version.
Modeling
- Occlude selection mode improvement Further optimizations have been made to the Occlude Selected functionality. The selection performance and accuracy has been greatly improved.
- Smart Extrude Improvement
- All updates which are provided in PUs such as partial cut-through functionality are now available in the Edit Poly, too.
- Fix for “zero-length” edge welding which is sometimes corrupting results when making very small extrusions with very large, high aspect ratio faces.
- The maximum number of height and cap segments, as well as sides, has been increased for the Cylinder, Sphere, Tube, Cone, and Torus primitives. Now they support up to 3600 sides, and up to 1000 height and cap segments.

- ADSK_3DSMAX_SMART_EXTRUDE has been added to globally disable Smart Extrude from operating on the Edit Poly modifier (which might be required for file compatibility with 3ds Max 2021 versions that do not contain this Smart Extrude functionality in Edit Poly).
- When Manipulate Mode is active, 3ds Max will now only display the manipulator for the active level of the modifier stack that the user is on (instead of displaying all possible manipulators).
- The XForm modifier is now versioned to enable it to provide the same level of visual consistency when loading older 3ds Max scenes. When opening older 3ds Max scenes (scenes from 3ds Max 2020 or earlier) the XForm modifier will default the “Perserve Normals” option to be OFF, enabling the scenes to be consistent with how the modifier previously operated
- Corrected an issues where it was possible for deforming World Space Modifiers (such as FFD and Noise) could crash 3ds Max when applied over top of modifiers that compute explicit normals (such as Edit Normals or Weighted Normals)
- XForm modifier created by ResetXForm is named “ResetXForm“.
Pipeline integration v2
- Added support for simplified usage of environment variables meant to customize the 3ds Max environment, without the need to define them per 3dsmax.exe process.At run-time, 3ds Max defines two process wide environment variables:
- %ADSK_3DSMAX_MAJOR_VERSION% – represents the major version of the 3ds Max (3dsmax.exe) process. For example “2023” for 3ds Max
- %ADSK_3DSMAX_MINOR_VERSION% – represents the minor version of the 3ds Max (3dsmax.exe) process. For example “1” for 3ds Max 2023 Update1
- The above env vars can be used in the env vars that support the customization of the user environment (ADSK_3DSMAX_***_DIR).
- For example, ADSK_3DSMAX_STARTUPSCRIPT_ADDON_DIR=\\server\3dsMax\%ADSK_3DSMAX_MAJOR_VERSION%.%ADSK_3DSMAX_MINOR_VERSION%\scripts\startup
- ADSK_3DSMAX_ENVVAR_TOKEN_SUPPORT – Enables auto-tokenization of 3ds Max installation files, similar to the -envartoken command line switch.
- ADSK_3DSMAX_AUTOBACKUP_DIR – Defines the path used by Autobackup to save files.
- ADSK_3DSMAX_ROOT – An environment variable defined by the 3ds Max process that contains the directory from which the current 3dsmax.exe program is running, regardless of where 3ds Max is installed. Only defined when auto-tokenization is enabled.
- ADSK_3DSMAX_USERTOOLS_DIR – The path for reading and writing user-defined tools, as well as MCG and Scene Converter scripts.
Rendering
- New Autodesk Standard Surface Compliant mode – Physical Material is now aligned with the Autodesk Standard Surface feature set when in to that mode. For this, the following 2 new features are added.
- Thin Film
- Sheen
- Update openEXR to version 2.5.7
- Updated OpenShadingLanguage (OSL) to v.1.11.16
MaxToA
- Upgrade to Arnold 7.1.0.0/MaxtoA 5.1.0
- Triplanar now with different texture on each axis
- The new and improved NVIDIA Optix 7 denoiser on GPU which allows for consistent denoising results across AOVs. This makes it possible to composite and assemble AOVs back together without any artifacts.
- Multiple optimizations and enhancements improving the experience when interactively rendering a scene. For example, interactive GPU rendering now performs better when handling heavier scenes through the implementation of a fixed minimum frame rate.
- Increased Arnold stability, especially when using multiple render sessions.
- Also MAXtoA 5.2.0 is available. It includes the new Viewport Volume Display. This feature allows volumetric objects to appear directly in the viewport while building and working on scenes.
Per-Viewport FIltering Improvement
- More MXS exposure include ViewportID property and IsNodeShown, OpenDialog|CloseDialog, ShowCategory and FilterChangeCallback.
- ViewportFIlter now supports Multi-Edit with CTRL/SHIFT.
- Enabled playback while changing Viewport Filtering settings
- Fixed – Per Viewport Filtering Icon was not visible with Safe Frame ON.
- Fixed – cannot select linked geometry with Show Renderable Only ON
- Fixed ghost when toggle filtering
- Fixed missing filtering on the group head or bone-only node
Security
- Safe Script Execution
- enum value MaxSDK::AssetManagement::AssetType::kScript An asset file reflecting any script file other than a pre- or post-render script file.
- enum value MAXScript::ScriptSource::Dynamic To be used for scripts that are dynamically generated at runtime and could contain input from various sources that are interpreted as scripted commands.
- Dynamic scripts will always execute with restricted security rights, regardless of Safe Scene Script Execution settings.
- ExecuteScriptAsset function Executes the given script file specified as an AssetUser. This function should be used for executing script files whose name is stored in the scene file.
- MAXScript::ScriptSource argument to ExecuteMAXScriptScript function specifies the security rights of the evaluated script string.
- Added additional .net types to whitelist of types that can be created by embedded scripts. This included adding Autodesk.Max.MaxPlus.Box3, which is used by MCG modifiers.
- Safe Scene Script Execution settings now apply to the NetworkManager.Send command when called from script embedded in the scene file
- MAXScript strings executed through the OLE IMaxRenderer interface are now executed with ScriptSource::Dynamic security rights
- Secure way for plugins to load binary dependencies 3ds Max will load dynamic-link libraries (DLLs) that plugins have a link-time (implicit) dependency on from the folder where the plugin resides. In other words, the DLLs the plugin depends on does not have to be installed in 3ds Max’s root folder (<maxroot>), nor does the plugin need to do extra work to load the dlls at run-time (by calling LoadLibrary() for example). Simply deploy the DLLs the plugin depends on side-by-side within the same folder where the plugin resides, and 3ds Max will be able to load the plugin
Core
- Improved scene file load performance of Scene Converter when file contains large number of missing plugin instances
- Improved visual appearance of progress bar in main 3ds Max UI
- Removed Missing Dlls Dialog as Scene Converter Dialog already displays the same information. Scene Converter Dialog now shows by default the list of missing dlls
- The following actions are now undoble and make the scene dirty properly.
- Changing Object Color and Object Properties
- Enabling/Disabling a modifier..
- Disabling a modifier in the viewport/renders.
- Fixed not being able to do Drag and Drop of scene file onto 3ds Max if scene file size was greater than 2 GB
- Microsoft Visual Studio 2019, version 16.10.4, C++ Platform Toolset v142, and Windows Platform SDK 10.0.19041.0
- Qt 5.15.1 and PySide2 5.15.1
- .NET 4.8
InterOp
- Improved FBX so now it supports the physical material and you can send to/from Maya without much loss of data.
Maxscript
- Scripted Bake To Texture Map plug-ins support using the CommonBakeMap and CommonBakeMapOperator classes.
- New functions for file attributes getFileAttributeNames(), getFileAttributes(), isFileAttributeSettable()
- Both meshop and polyop now have functions to return an array of vertices or faces that match a specified material ID: meshop.getFacesByMatid <mesh> <matID> meshop.getVertsByMatid <mesh> <matID> polyop.getFacesByMatid <poly> <matID> polyop.getVertsByMatid <poly> <matID>
- New “stepName” argument was added to progressUpdate() function, and New “allowCancel” was added to progressStart
- The “windows” struct contains a new member, isWindowEnabled HWND, that returns true if the specified window is enabled (able to recieve mouse and keyboard inputs). The new getFocus() function returns the HWND of the window that currently has focus.
- Fixed assigning a reference object for Symmetry and Slice modifiers through Maxscript could crash.
- Fixed argument count checks for MAXScript functions getSubTexmapSlotName, getSubMtlSlotName, getClassName, and getObjectName to allow localizedName: keyword argument to be specified.
- Fixed issue where could not specify subAnim keyword argument for type paramBlock2 parameters in scripted plugins.
Python
- Python 3.9.7 – 3ds Max ships with the visual effects platform-recommended Python 3.9.7. which boasts performance improvements, new string functions, and improved quality that will aid Technical Directors and pipeline integration.
- C++ function called DisableMaxAcceleratorsOnFocus has been exposed in the qtmax python module. This is a helper function that disables 3ds Max accelerators on Qt widgets
Plugin Packages Improvement
- The Plugin Package description file (PackageContents.xml) now supports environment variable definitions of type string and path.
- Addition of Hotkeys specification in plugin package file – PluginPackageManager was extended to support a new component type ‘hotkey parts’. 3ds Max will load plugin sourced keyboard shortcuts from the specified location.
Volume Display API
- This new API simplifies displaying a volume in the viewport when a plugin provides the voxels data, positions and display options. 3ds Max will convert the voxels data on the GPU and display it according to the different supported viewport modes such as wireframe, shaded etc. This API proposes many options for the display such as: bounding box, wireframe, voxels, volume with a voxel color and opacity, black body, turbo gradient, or gradient custom texmaps color modes are also available. So far, it supports the volume grids of type fog and level sets. You can use a slice axis to show only a part of the volume at display time. The voxels grid data can be normalized automatically, or manually, or not normalized at all. You can use a 1D density transfer texture to remove some parts of the voxels data at display time, so a 3rd party can control how the volume looks. It also provides support for selection hit testing and wireframe display
Instance Rendering API
- This new API provides a consistent way for third party developers to provide instancing data for a Renderer. It removes the requirement of having to implement such logic in the renderer itself or in any given plugin. The API has two different clients, Producers and Consumers. Third party tools such as tyFlow and Thinking Particles can be considered Producers, they can generate data from their plugins using the new API and Renderers such as Arnold, Vray or Corona are consumers as in they use the API to retrieve the data generated by the producers
- Class RenderTimeInstancingInterface allows a renderer to access an object’s instancing information so that it can do efficient instancing at render-time. This interface is implemented by an object and called by a renderer. A renderer should not call the object’s GetRenderMesh() method if the object supports the RenderTimeInstancingInterface interface.
- Instantiating INodes and Meshes.
- Overriding the material of instances.
- Overriding the material IDs of instances.
- Linear and curved motion blur using 2 or more transform matrices.
- Deleting meshes when they are flagged as requiring deletion.
- UVW overrides
- MaxToA support this API.
Instance Display API
- This new API allows an object plugin to display many instances in the viewport without creating them all in the scene. The plugin describes the instance data based on a single object, and 3ds Max creates efficient representations of that object on the GPU. The instances can have different transforms, materials, mapping3 coordinates, and vertex colors. Examples of plugins that would benefit from using this API are particle systems, scattering tools, instancers, etc.
- To take advantage of this API, plugins should use the methods of class InstanceDisplayGeometry, which are implemented by 3ds Max. For more details, please see maxsdk\include\graphics\InstanceDisplayGeometry.h, and the sample project located in maxsdk\howto\objects\InstancedObject\ folder of the 3ds Max SDK
Max to viewport material conversion API
- Additional helper functions in MaxSDK::Graphics::MaterialConversionHelper.
- To convert from a 3ds Max material (Mtl class) into a Nitrous viewport material (BaseMaterialHandle class) with the function: ConvertMaxToNitrousMaterial.
- And to create a Nitrous viewport material from a physical material preset with the function: GetNitrousMaterialFromPhysicalMaterialPreset
Fixes
- Corrected an issues where it was possible for deforming World Space Modifiers (such as FFD and Noise) could crash 3ds Max when applied over top of modifiers that compute explicit normals (such as Edit Normals or Weighted Normals)
3dsMax 2022.3
Per-Viewport Filtering – New
- You can hide/unhide objects by category or by class per each viewport. Each viewport’s settings can be set independently from one another, giving you the flexibility to display what you need in a given viewport. Per-Viewport Filtering does not affect the scene or renderer.
- Copy/Paste filter setting between viewport
- Shift+K to toggle on and off the viewport filter
- Full MXS exposure with ViewportFilter interface
- Per view settings/preference dialog is modeless and dockable now
Pipeline integration – New
- Environment Customization Enable studios to configure the software and enable their artists to easily switch between projects that require a uniquely configured environment, script, and plug-in environment using environment variables.
- The following paths used by 3ds Max can now be configured using environment variables.
- The ADSK_3DSMAX_x64_<year> – The path to the 3ds Max install. Created by the installation process. On systems where 3ds Max was copied instead of installed, this variable needs to be defined manually.
- ADSK_3DSMAX_APPDATA_DIR – The path used by 3ds Max to read and write local user data. By default this location is C:\Users\<username>\AppData\Local\Autodesk\3dsMax\<year> – 64bit\<lang>
- ADSK_3DSMAX_USERSETTINGS_DIR – The path for reading and writing user settings.
- ADSK_3DSMAX_PROJECT_DIR – The path for the location for project data (such as material libraries, render presets, render output, etc).
- ADSK_3DSMAX_STARTUPSCRIPTS_ADDON_DIR – 3ds Max Startup Scripts Folders.
- ADSK_3DSMAX_SCRIPTS_ADDON_DIR- 3ds Max User Scripts Folders.
- ADSK_3DSMAX_MACROS_ADDON_DIR – 3ds Max User Macro Scripts Folders.
- ADSK_3DSMAX_ICONS_ADDON_DIR – 3ds Max User Icons Folders.

ADSK_3DSMAX_ASSETS_MAPS_DIR – A list of semicolon-delimited paths, used in addition to the Xrefs paths defined in the Configure Project Paths dialog. ADSK_3DSMAX_ASSETS_XREFS_DIR – A list of semicolon-delimited paths, used in addition to the External Files paths defined in the Configure Project Paths dialog.
- Support for Environment Variable Tokens in Paths found in Configuration Files This feature allows users to define or modify paths found in various 3ds Max configuration files, including 3dsmax.ini, using user defined environment variables, referred to as “environment variable tokens”.
Advanced Wood OSL shader – New
- designed to match the accurate appearance of many common wood types such as maple, walnut, and oak. Delivering a rich and vibrant result that is easy to configure, displays beautifully in the viewport and in any OSL compatible renderer.
- UVW can be modified with external shaders, and a random seed can be driven to have per-object variations.
- It is also fully supported in a ‘High Quality’ viewport and will render exactly the same on any OSL capable renderer.
SketchUp 2021 Support – New
- allowing users to successfully import SketchUp 2021 models into the software where they can continue to model and render the asset.
MaxToA/Arnold
- Arnold 7.0.0.0.
- color_curves imager
- Intel open image denoiser imager
- EXR’s multipart parameter
- The Tonemap Imager now supports a Look-up Tables (LUT) mode to apply to a LUT file in any format supported by OCIOv2.
- Arnold lights also now have new defaults that give better first render results, along with sticky settings that allows you to create lights with the same setting as the light previously created.
Performance Improvement
- Resolved Viewport Lag from High Polling Gaming Mouse Devices issue where the viewport performance in Standard or High Quality mode would be affected by the high polling rate from gaming mouse devices.
- Further optimized the File Save system to provide an additional 20-40% percent boost in efficiency.
- Improved scene load performance when a large number of animation clips are present in the scene. For example, a provided user scene file with half a million clips opened 10 times faster.
Modeling Improvement
- Occlude node – marquee(box)/paint selection support
- Smart Extrude – overlap is treated properly in multi-body cut-throughs.
- Smart Extrude – treatment to deal with when either the extruded faces or the target face were significantly non-planar. Now, under the hood we split all faces along any non-flat diagonals at the beginning of the operation, and re-merge them at the end, so arbitrarily non-planar faces now work just as well as planar faces.
- Symmetry modifier – a new “Slice Cleanup Threshold” to the “Slice Along Mirror” option has been added in 3ds Max 2022.3. This threshold will allow you to further control the cleanup of vertices that are in close proximity to one another along the cutting plane before the Symmetry action takes place.
- Unfold3D Peel/Pack – Further improvement on non-manifold map topology automatic fix
- Unfold3D Peel/Pack – Proper MXS support for Unfold3D pack. Now users can choose Unfold3D as .pack methods and use all arguments of the method.
- Chamfer modifier – “Limit Affects” functionality has been updated to generate improved results on non-planar faces and non-collinear chamfered edges.
User Experience Improvement
- Orphaned Layers – When loading or merging a scene, orphaned layers and objects with no parent layers are now automatically recovered and can be interacted with once again.
- Auto-Expand Selection in Scene Explorers is now off by default.
- Show Selection Range – Show Selection Range in the Time Slider configuration is now on by default, making it easier to quickly scale the range of a selected set of keys.
- LookAt Constraints Viewline Length – Viewline Length Absolute inLookAt Constraint is now off by default.
- Installation from Hidden Folders – Now supports being installed and launched from a hidden folder, enabling the software to be more easily deployed.
- Searching using partial material’s names in SME views enabled.
- Fixed possible freeze with long shader tree can when right-clicking on the material in SME.
Software Security Enhancements
- When Safe Scene Script Execution is enabled in 3ds Max 2022.3, scripts embedded in a scene will now prevent writing to folders where 3ds Max expects to find plug-ins and scripts.
3dsMax 2022.2
Unfold3D Peel – New
- Unfold3D is the default algorithm used for the Peel functions now inside of 3ds Max with the Unwrap UVW modifier.
- In the Edit UV window of the Unwrap UVW modifier you will see that the Peel section has changed to reflect a new set of options. A rollout menu is now provided so that you can choose to use the old LSCM method from before, or stick with Unfold3D
- Peel, Peel Mode, and Reset Peel should all function as expected. Peel will unfold based on the UV coordinate selection as they exist. Peel Mode brings you into the interactive peel function. Reset Peel will take your selection, generate a new set of UV data and unfold them.
- The options menu has also been updated to reflect Unfold3d’s various parameters for unfolding, or to access the settings for the legacy algorithms
Unfold3D Packing – New
- Unfold3D requires clean non-manifold topology for processing. The Unwrap UVW modifier will check your UV data to and fix the problematic data such as degenerate,or non-manifold uv data or stacked & welded elements.
- By default the Unfold3D packing algorithm is also the default for all packing actions and is hooked into the same settings and options from before that are found in the Edit UV window.
- A new options menu exists where you can further refine the packing options, or switch to the other algorithms within 3ds Max that we provided before for packing.
Unfold 3D Optimize – New
- Unfold 3D Optimize is added in the Relax method dropdown.
UV Editor Performance Improvement
- Improved performance of selection and uv manipulation by multithreading and optimizing memory allocations of topology validation and selection algorithms. Also threaded and batched data gathering for uv window painting.
- Tested with 26 files ranging from 4k verts to 2.7 million verts.
- Adding unwrap_uvw modifier – 486% faster (108% – 869%)
- Opening UV editor – 175% faster (104% – 238%)
- Switching sub-object mode from verts to faces – 174% faster (107% – 245%)
- Switching sub-object mode from facesto verts – 296% faster (109% – 578%)
- Selecting sub-object mode – 174% faster (114% – 229%)
- Transforming sub-objects – I couldn’t measure this with script. But, you can see this is at least 2-300% faster from my video.
UV Editor Updates
- The UV Editor’s default size is updated to be adaptive to the screen resolution on the end user’s machine. By default the Edit UV window will open centered and at 80% of the users screen resolution size. Changes to this window’s position and size are also saved.
- A small progress bar has been added to the Peel rollout in the Edit UV window to help inform the user about the status of a Peel or Pack action that Unfold3D has been told to perform.
- Users can cancel a Peel or Pack action by pressing ESC.
- The default blackand white checker map that is used in the Edit UV window to help with UV mapping is now generated at a higher resolution (2048). A user can further adjust this resolution up to 8192 in the Unwrap Options
File Save Performance Improvement
- File save code has been greatly optimized by caching data instead of recalculating it, minimizing moving file pointers, eliminating the object creation\destruction and setting\clearing flags instead.
- Tested with 10 files which took more than a few seconds to save previously. The file save without compression is now 193% faster and 423% faster with compression on than 2021.3. So, turning on compression makes the file save 360% slower compared to 673% slower in 3dsMax 2021.3.
Smart Extrude – Multi Cut-Through & Partial Merge
- You can now drag a face through multiple surfaces, or drag a face partially through a volume of a mesh and it will cut and clean the geometry as expected.
- It has been enhanced to produce more accurate results that might occur from numerical precision on overlapping faces.
- Improved Smart Extrude stability when quickly moving the results back and forth before committing to a final position.
Pen Pressure Improvement
- More device support as long as they support Wintab32.dll. (E.g. Huion, XP-Pen)
- support the full range of pressure sensitivity that is offered by the pen tablet device by checking with the Wintab32.dll on your local Windows system. (E.g. Huion Kamvas16 support 8192 level)
- Brush pressure from pen tablet input devices is now properly captured by 3ds Max and can be utilized once again in various tools/functions within the application that supports this functionality. For best results, disable Windows Ink
Performance
- Accelerated moving verts in editpoly by not locking for every getnormal.
- Improved loading performance if SME is open and there are heavy shading trees
Improved Hide by Category
- New Qt UI
- New Show Renderable Only checkbox
- New Scene Contents to show only categories which exist in the scene.
USD b0.2
- Supports exporting animation data such as node transform animations and vertex animation cache.
- Added basic support for exporting splines.
- Enhanced support for exporting and importing Photometric Lights.
- Enhanced support for exporting and importing cameras.

- Added options to control export of map channel data from meshes.
- USDView now available with required dependencies.
- Mesh conversion function available in MAXScript to create mesh from a USD Prim.
- New export option to control polygon triangulation.
Modeling
- The Symmetry modifier’s welding algorithms have been updated to provide even more predictable results by finding matching pair vertices on the mirrored surface. The tolerance threshold now enables welding to solve across open gaps along the symmetry line. These enhancements will make symmetry operations faster and more accurate than before, even on open surfaced models.
- Symmetry now performs a check for non-manifold edges and vertices. It will attempt to clean incorrect mesh data when these errors are found. This will help resolve issues with vertices being accidentally welded to other vertices on other elements after using Symmetry.
Security
- Security Settings Management -: 3ds Max now supports management of security settings by IT administrators by specifying and locking the Safe Scene Script Execution settings through the registry. This allows for all installations to use the same security settings, which helps define team or studio-wide software security policies.
- Support3ds Max now logs all Python scripts and imports. If a module is imported multiple times, it’s logged only once per 3ds Max session
Core
- The ADSK_APPLICATION_PLUGINS environment variable can now list the folder where the PackageContents.xml file of a plugin packages is located. This allows for finer control over organizing plugin packages and providing 3ds Max with the paths to load them from.
Maxscript
- enableColorMap and useRGBColorMap properties added to StandardTextureOutput MAXScript exposure. Setting on any of the properties via MAXScript for StandardTextureOutput updates display in Compact Material Editor and Slate Material Editor.
- When a hyperlink control in an embedded scene script is clicked, a security warning dialog is displayed to confirm that the user trusts the target website.
- The getINISetting() function now takes an optional defaultValue keyword parameter that defines a value to return if the specified key is not found.
- The new getEncoding() function returns the character encoding of a specified text file.
Python
- It is now possible to execute pyc files in 3ds Max.
- The Python interpreter runs with the -E switch.
Fixes
- Fixed issues related to cloning of script editor tabs in MAXScript editor.
- Resolved an issue with the Symmetry modifier where it would merge vertices there were in close proximity to one another together before stitching the mirror results together.
- Fixed issue where user could not add Tracks to Track Sets.
- Fixed an issue that caused the getINISetting MAXScript function to change the encoding of the files it read to UTF-16 LE with BOM. Now the original encoding of files is always preserved when they are read using getINISetting.
3dsMax 2022.1
Explicit Normal Performance Improvement
- Last year I have posted a tip about “3dsMax tips #3 How to make imported tree animation 15 times faster”. /3dsmax-tips-3-how-to-make-tree…/
- In that post, I hinted 3dsMax dev is working on improving the situation. Finally that effort come to fruition and released in 2022.1. Now all explicit normal computation is fully safely multithreaded. My test shows 2x to 4x “overall” performance improvement. The video I attached has 4 of 25k verts characters with explicit normals(total 100k deforming verts). It went from 9 fps to 36 fps! This was no simple task and touched the core of 3dsMax. As you can see from the last a few release, 3dsMax team is putting a lot of effort for modernizing the core and improving performance.
New Selection Filters for Editable Poly and Edit Poly modifier – Occlude mode
- Two new Optional Culling selection filters, Backface and Ignore Occluded, have been added to Editable Poly and the Selection Rollout for Edit Poly modifier. When enabled, artists will be able to only select the components (vertices, edges, polygons) that are visible in their view. Hence, making it easier to select visible components only and preventing you from unintentionally selecting components that are occluded from view. These options replace the legacy Ignore Backfacing toggle. In addition, Target Weld and Bridge poly functions now perform better with these options enabled.
Restore Factory Settings & Startup Failure Recovery
- A new Restore to Factory Settings button has been added to the General Preferences tab to let you restore 3ds Max default settings from within the software if you experience unexpected UI behavior or performance issues. Everybody knows “Deleting ENU folder” trick to solve many odd issues. But, you also lose user macros and script by doing so. Also you have to remember those hidden folder location. Bow, 3dsMax will reset only needed setting for you with a button. Also it will give you one click shorcut to access the folder.
- On launch, if 3ds Max detects that initialization has been corrupted in a way that prevents it from launching, a Startup Failure Detection window now appears. (You can ignore the dialog and continue without restoring. If 3ds Max continues to fail at startup, the option will still appear.)
Modeling
- Smooth Modifier to Clear Explicit NormalsAs a part of explicit normal handling improvement, Smooth modifier now clears explicit normal interface completely for Poly object. You can see the technical details at the above my tutorial link.
- Vertex Paint ImprovementsSub-object component selections can now be passed up the modifier stack to the Vertex Paint modifier. This will enable artists to utilize the component selection as a mask to control where you can paint. Vertices of hidden faces are no longer selectable with your mouse when using Vertex Paint.
Performance
- Smart Extrude Performance ImprovementThis update brings significant performance enhancements(over 20x) to Smart Extrude allowing you to perform Smart Extrude actions to a selection of polygons on their models faster than ever before. You can also apply these actions utilizing higher polygon counts than what was previously possible.
- 3dsMax scene mesh to viewport display gpu mesh conversion has been improved.
- Noise map multi-threading handling has been improved.
- The performance of the selection of objects in the viewport with SME opened has been improved.
MaxFluid
- Fluid Loader Particle ID Exposure to Particle InterfaceNow any particle system that support particle interface can directly read/update MaxFluid properly.
Core
- No more MentalRay missing plugin error new mechanism (came with a new SceneConverter API – AddSilentClassID ) was introduced in 2022.1 to allow to hide any missing plugin data (e.g., from MentalRay). In English, you wouldn’t see this popup anymore. It doesn’t matter if the missing plugin data is in xref or material library. The new feature will simply ignore them and will not show popups.
InterOp
- Improved Support for Vertex Colors in FBX ImportsVertex Colors are now supported in FBX imports from a broader set of sources, enabling greater collaboration opportunities across different creative tools with less compromise.
Fixes
- Only 1 click necessary to work with Render Setup properties if focus is elsewhere in Max.
- Fixed Perspective Match handles behavior.
- Animation keeps playing while the view is moving/panning/orbiting.
- Resolved an issue where Xform modifier gixmo was always displaying in the viewport, even when the object it was applied to was not selected and it was not the active modifier on the stack.
- Preferences saving issue with V-Ray installed
- Weighted edges that are set as 0 in Editable Poly or the Edit Poly modifier Chamfer by weight will now produce proper results when using Chamfer and “By Weight”. Any Chamfer modifier applied within 3ds Max 2022.1 Update will now utilize this new code to handle edge weights when chamfering.
- Fixed issue introduced in 3ds Max 2022 where strings used as initialization values for structures, scripted plugins and scripted rollouts were not properly handled, resulting in code that could change the content of the actual string literal.
- Fixed command panel rollouts not expanding or retracting
- Solved issue with .psd files locked in Photoshop.
- PBR Importer rules can now recognize spaces in texture names.
- Fixed a bug that prevented maxscript from writing to the listener window when called from python.
- Fixed the save of sequences from Make Preview when Multi Pass is enabled.
- Anim Layers were not being removed when the the controlling node was deleted. Now when a node is deleted any anim layers referencing that node are also deleted. Also on file open/merge anim layers that are orphaned are deleted.
3dsMax 2022
Smart Extrude
- Smart Extrude Cut-through removes geometric data when the smart extrude passes to the other side of faces.

Revamped Slice/Symmetry modifier
- Multiple axis slice planes with Planar slicing/symmetry. This allows you to slice/symmetry on X, Y and Z axis at the same time. You can flip any of the individual axis to get the desired result.
- Radial slicing Radial slicing along one plane (z by default). You have control over the two angles up to 180 degrees.
- Radial symmetry enables a new symmetry function to quickly duplicate and repeat your geometry around the gizmo center to rapidly create new variations and empower your workflow. You can use as rasial array, too.
- Mirror option for Radial Symmetry Mirrors each radial symmetry part to create seamless connection between each part.
- Pick Face option for Planar slicing/symmetry allows you to quickly align the slice plane to any face of the object that the modifier is applied to.

Safe Scene Script Execution
- 3dsMax will block the execution of scripted commands found in the scene that could be used for malicious purposes. The same commands found in script files (*.ms, *.mse, *.mcr, *.py, etc) will not be blocked. Safe Scene Script Execution (SSSE) is enabled by default
- The Safe Scene Script Execution settings can be found in the Security tab of the Preferences dialog The commands being blocked fall into these categories: 1) Maxscript system commands: these are commands that allow access to resources outside the 3ds Max scene, such as file system, process execution, network and internet. Examples include DosCommand, ShellLaunch, createOLEObject, LoadDllsFromDir, 2) Python commands: these are commands that allow for executing python code from Maxscript. Basically the methods of the Python Maxscript interface are all off limits. 3) 3rd part .NET code: instancing of .NET types that 3ds Max does not use are disallowed from scripts embedded in a scene file.
- User friendly notifications on blocked scripted commands When a scripted command is blocked, a message is displayed in our new modeless Security Message window, and it’s displayed in orange to indicate that it’s new (hasn’t been read yet). the blocked command icon in the status bar will increment the count of blocked messages and turn orange for a little while the plugin\feature that owns the script containing the blocked command will pop open. The message that displays the name of the blocked command, also displays the parameters passed to the command
- Security Tools integrated into Security preferences You can enable\disable the Security Tools from the Security preferences tab – see the “Malware Removal” section.

- Evaluating macroscript definitions and running macros.new or macros.load are blocked when called from embedded script and Safe Scene Script Execution is enabled.
- The dotnet.loadAssembly <assembly_dll_string> method is blocked when called from embedded script, Safe Scene Script Execution is enabled, and SSSE execution of .Net is disabled
- Unsafe dragAndDrop FPS methods are blocked by the Safe Scene Script Execution feature
