Unofficial 3dsMax What’s New

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 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


  • 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 export option to include/exclude hidden nodes.
  • 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.


  • 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 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


  • 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.


  • 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.


  • It is now possible to execute pyc files in 3ds Max. 
  • The Python interpreter runs with the -E switch.


  • Fixed issues related to cloning of script editor tabs in MAXScript editor. MAXX-53004
  • 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. MAXX-64434
  • Fixed issue where user could not add Tracks to Track Sets. MAXX-606670
  • 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. MAXX-62470

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”.…/
  • 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

  • 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.)


  • Smooth Modifier to Clear Explicit Normals
    As 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 Improvements
    Sub-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.


  • Smart Extrude Performance Improvement
    This 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.


  • Fluid Loader Particle ID Exposure to Particle Interface
    Now any particle system that support particle interface can directly read/update MaxFluid properly.


  • Improved Support for Vertex Colors in FBX Imports
    Vertex Colors are now supported in FBX imports from a broader set of sources, enabling greater collaboration opportunities across different creative tools with less compromise.


  • Only 1 click necessary to work with Render Setup properties if focus is elsewhere in Max. MAXX-59336
  • Fixed Perspective Match handles behavior. MAXX-63003
  • Animation keeps playing while the view is moving/panning/orbiting. MAXX-63031
  • 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. MAXX-56425
  • Preferences saving issue with V-Ray installed MAXX-63353
  • 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. MAXX-62703
  • 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. MAXX-63459
  • Fixed command panel rollouts not expanding or retracting MAXX-63409
  • Solved issue with .psd files locked in Photoshop. MAXX-61825
  • PBR Importer rules can now recognize spaces in texture names. MAXX-63382
  • Fixed a bug that prevented maxscript from writing to the listener window when called from python. MAXX-63391
  • Fixed the save of sequences from Make Preview when Multi Pass is enabled. MAXX-53168
  • 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. MAXX-62018

  • PU2 – Smart Extrude
    Adjacent faces are completely rebuilt and stitched together, matching the final visual output. No more need for time-consuming repairs on hidden faces or other geometric data resulting from extrusions.
  • PU1 – Interactive Extrusion and Inset(AKA Shift Extrude/Scale)
    Users can now utilize a Shift+Drag (left mouse button) with the Move transform tool to extrude polygon component selections when using an Editable Poly or an Edit Poly modifier.
    Shift+Drag with the Scale transform tool now performs a polygonal inset action on selected polygon component selections when using an Editable Poly or an Edit Poly modifier
    Clone/Copy actions are now performed with Ctrl+Shift+Drag when using the Move transform tool on the polygon component on and Editable Poly or an Edit Poly modifier.

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.
  • Pick Object
    picking a different object in the scene to drive the transform of the slice/symmetry. Gizmo transform. This makes it much easier to animate the gizmo. Almost like having a local and world space modifier in one.
  • Improved Performance. 2x faster than the original slice modifier.
  • Smarter Weld Seam
    modifier actually knows what vertices are split from one another and welds them back based on the slice plane instead of blankly weld by distance threshold. The edges not being sliced (generating new vertices) aren’t considered. It allows to weld vertices from different elements of a mesh in a smarter way
  • Cap(Slice)
    open holes created by the Slice operation can now be capped along its boundary edges.
  • Set Cap Material(Slice)
  • Automatic selection for capped faces(Slice)
  • Automatic Operation mode(Slice)
    Slice modifier will use the same data type coming from stack  by default.

Improved Relax modifier

  • Fullt multithreaded for better performance. A test shows 3.5x improvement over 1.1mil verts and 2.2mil tris
  • Preserve volume option

Improved Extrude modifier

  • Optimized capping provides significant performance improvement for complex shape with a lot of elements. A test on a spline with 220 spline and 523,176 points was 130 times faster than before(3576 second vs 27.7 second).
  • Capped geometry is cached. Therefore, the extrude updates instantly when the amount value is changed.


  • A brand new Retopology modifier
    3 automatic retopology algorithm. Reform, QuadriFlow, InstantMesh
  • Reform
    the proprietary retopology algorithm, reconstructs problematic polygonal mesh data as clean quad-based topology with uncompromising accuracy.
  • QuadriFlow and InstantMesh for quick retopology.
  • Various hard edge preservation options.
    Material ID, UV, Boolean Seams, Specified Normals, Selected Edges, Angle

Improved Subdivide modifier(PU3)

  • 3 new algorithms for remeshing
    Variable Curve
  • All three algorithms can preserve existing mesh data include UV on the output result
  • The pre/post processing was threaded, and some obvious sources of inefficiency were fixed.

New Path Deform modifier(PU3)

  • Completely rebuilt while retaining backwards compatibility with older scenes.
  • Fully multi-threaded average 400% faster. 1 million verts test showed 1700% improvement.
  • Support for per element path deform, control the pivot for each element and whether the elements are deformed individually or as a group
  • Utilize nodes with multiple curve elements to transition the path deform from one shape to another
  • Preserve form by element – The objects form is now maintained when moving along the path
  • Texture coordinates are properly transferred from the path to the object (and will no longer crash 3ds Max)
  • Preserve form by Group – Grouped object positions are now

Improved Push modifier(PU2)

  • Fully multi-threaded average 300% faster.
  • Vertex normals are now cached, maintaining their input normals when a push operation is applied to them. This provides an added performance for animation.

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.
  • Unsafe dragAndDrop FPS methods are blocked by the Safe Scene Script Execution feature
  • 3dsmax.exe (3dsmaxio.exe), 3dsmaxbatch.exe and 3dsmaxcmd.exe all support the command line options and env vars for controlling Safe Scene Script Execution.
    command-line option for all flavors of 3ds Max : ‘- safescene [on|off]’
    environment variable ‘ADSK_3DSMAX_SAFE_SCENE’ (with ‘[1|0]’ values)
    The order in which the settings are read and applied (the last valid in list is the one retained): 3ds Max ini file, environment variable, command-line
  • Evaluating macroscript definitions and running 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
  • The Malware Removal functionality also has an option to notify the user of updates available to the Security Tools on Autodesk App Store.


  • Accelerated Auto Smooth.algorithm
    EditableMesh and EditablePoly AutoSmooth command, EditMesh and EditPoly Autosmooth command, Smooth modifier and Renderable Spline with Autosmooth on. The performance gains are significant. One of the test models took 2.8 second compared to 6664 second before. 3000 times faster!
  • Faster EditPoly Remove Edges and to a lesser extent, Remove Vertices
    EditPoly Remove edges (with ctrl on) and Remove vertices in various places (including EditablePoly). A test which removed 238,800 verts from 318402 verts showed 2,533 times improvement. 2021.3 took 4276.9 second, and 2022 took 1.688 second. This change break backward compatibility. This means you will not see improvements when loading old files. Only the newly added Edit Poly modifier will use this improvement.
  • Accelerated mesh clusters.
    A test model with Bevel Faces and Chamfer Edges processed in 4 second compare to 1 minute 25 second before.
  • Accelerate an internal controller data structure “TempStore”
    This optimization improves key creation speed. this can improve file loading of scenes with a bazillion keys (since you have to “create” all those keys on file load). And it may improve performance of operations that destroy/create many keys at once (for example reduce key). It also comes with a tiny (very tiny) bump in speed for most controllers
  • Update geometry library to conform to c++11 object creation/destruction
    3dsMax geometry library has been modernized to help performance and stability. it could improve modifiers that work with geometry a lot (and use standard containers & algorithms). We also made our matrices safer (they could read corrupted memory, causing crashes or bad values)
  • Optimized Attachment controller
    added math optimizations and the ability to cache the data so that playback speeds are improved after the data has been loaded and played the first,
  • PU3 – The initial MAXScript heap size allocation is increased from 15 MB to 100 MB, which can improve performance when the Ribbon is open.

  • PU1 – Anim Layers were not being removed when 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.
  • PU1 – Improved file loading, saving, and/or merging when dealing with Motion Clips
    we now cull out orphaned motion clips that are unreferenced. ParamBlock2 post load callback speed has also been improved.
  • PU1 – Added Track View action item called ‘Delete Selected Custom Attributes’ to delete any selected custom attributes in the active Track View and help reduce file bloat issues. It is only enabled when a Custom Attribute is selected.


  • Common Maps
    extend bake elements that users can pick to quickly achieve desired results. – The following maps are supported in 2022.
    Beauty, Color, Metalness, Roughness, Vertex Color, Emissive, MaterialID, Material Input, Opacity, Normal, Ambient Occlusion, Rounded Corners.
    Any renderer can “hook” into those Common Maps to define how they want to best bake that common map. Common Maps are MaxScript based for 3rdparty to support easily. If a Common Map is not supported by a renderer yet, it will display as unsupported (barred teapot icon at the beginning of the line).

    Enhanced functionality controls what knots are influenced through minimum angle parameters. The calculation of knot positions after fillet/chamfer operations has also been improved to provide optimal results.
  • PU3 – Improved hit detection for selections
    Implemented improved methods to handle pick selection when there are multiple components under the users cursor. This includes finding near or neighboring selection options to the cursor and comparing screen (z) depth to be more deterministic.
  • PU3 – Depth cycling issues for selection have been fixed.
    When you try and cycle through verts/edges/faces that are directly in front of or behind other verts/edges/faces, it no longer makes a selection of the different components when in Edit/able Poly.
  • PU3 – Updated the Bridge operation to provide improved mesh stability to look for and remove dead vertices to make the mesh safe once it has completed its action. Other poly actions in 3ds Max have also been enhanced to look for this same problem as well.
