3dsMax 2019 – OSL shader pack 1

While I was beta testing 3dsMax 2019, I made a few OSL maps. Nothing spectacular. Most of them are just “artist-friendly” pre-made setups to save some nodes.

Download OSL shader pack 1 or at http://UncleBobsShaders.com. Make sure to visit Uncle Bobs Shader Emporium for cool OSL shaders!

UVW > MatCapUV

This is a renderable version of my superClayMode script. Plug into the UVW slot of Bitmap Lookup.

Value > Color by Colorspace

You can conver to a vector value of other color space to RGB.

Math\Color > RGB to Other(Color)

You can convert a color from RGB to other color space. Output value is vector. after you process it, you can convert back to RGB with Color By Colorspace

Switchers > Random Index by Number/Color

It generates random integer index by number or color input. When you need to randomize something by Object ID, Materaal ID, Node Name and Node Handle, this map will be very handy. Of course you can also do the same thing by assembing a few other maps. I just made as one map for your convinience.

Math\Float > Sine wave function of frames

You can generate sine wave of time. It supports amplitude, period, phase value and square wave option. Check my sample animation. This map is very handy when you need to make some cyclic map animation.

!!! You DON”T need to connect Frame Number input. It already has float expression controller assigned. !!!

Scene > Normal

You can get normal value of pixel in various spaces.

Falloff

Falloff map OSL version. It supports Perpendicular/Parallel and Towards/Away.

BlendModel

Legacy Composite map OSL version. It supports all bklending mode in legacy Composite map. I was trying to support all Photoshop mode. But, I gave up on Vivid Light and Linear Light.

Here is a QC image that shows this map and legacy Composite map are producing the same result.

How to Install

1. Make “OSL” subfolder in any plugin folder
2. Unzip and copy *.osl files into the folder

A sample max file

Here is the shader tree for the animation. I used the distance from local center and random sin wave as the light intensity. No keyframes al all. The max file is included in the shader pack .zip file.
