This is the repo to hold shared OSL shaders for 3ds Max 2019 and beyond. Note that 3ds Max 2019 is the first version to support this standard.
All shaders in this repository are under the Apache 2.0 License - see LICENSE.txt. This is an extremely permissive Open Source License, where you can share, modify, use (even commercially), abuse, modify, tweak, break, mangle, or do whatever you want with any of the shaders. This is true also for the shaders that ship with 3ds Max itself. We believe in being Radically Open with this project. ENJOY!
For developer documentation, read The OSL Map and You.pdf, and for more user-facing information - as well as documentation for the 101 shaders shipping with 3ds Max - read OSL shaders in 3ds Max 2019.pdf.
The shaders shipping with the current version of max, and updates to them. The intent of this folder is that it should be safe to replace your 3dsmax\OSL folder with the content from here. It should only contain safe (compatible) updates to the shaders shipping together with max.
Non-shipping are under the OSL directory, with a few sub-folders. They are all under a main "OSL" folder. This allows you to add the folder checked out from GitHub as a plugin folder.
Go to Customize -> Configure System Paths -> 3rd Party Plug-Ins and add the checked out folder as a plugin path. 3ds Max will find the "OSL" subdirectory and automatically load everything in it at startup, and populate the material browser.
Contains shaders in flux and in development that may change completely tomorrow. Use these with caution, and its probably safest to use them in unlinked mode, because if you download a new version in the future, the behavior may have changed enough such that your old scenes no longer work.
These are shaders that are mature enough and stable enough that the intent is that the shaders interface and behaviour won't substantially change in the future. It may gain parameters, but defaults should be compatible with the previous version. These shaders are candidates to be included in the shipping set in the next version.
These are shaders submitted by users.
