Welcome to RenderMan for Maya 22!
This latest release of RenderMan for Maya 22 (RfM), includes a number of features to address feedback as well as some fixes to RenderMan for Maya workflow and performance.
Please see the release notes below for all the new capabilities and known issues! You may also wish to visit the migration page for selected highlights.
Now in RfM, problems caused by the presence of non-ascii characters in file paths (diacritics, etc.), RfM will error early (fail to load) with an informative message and warn if rendering resources are loaded from non-ascii paths. Please avoid accents, symbols, spaces, and other non-standard naming conventions in file paths, source files, and user names.

Known Limitations
RenderMan for Maya
- Light Linking volumes is not currently supported
- Only motion blurred meshes and transforms retain their blur after frame changes during IPR
- Deselecting "Receive Shadows" does not work.
- Creating a mesh light from existing geometry during IPR will duplicate the geometry in-render. Restart the render to remove the duplicate.
- We do not support Camera Facing Curves in Xgen
- Xgen will not reflect changes in the Collection
- Limited UDIM texture support in viewport
- Maya Fur Feedback is not supported
Xgen : Xgen will crash during live rendering unless you set Window > Preferences > Xgen > Multithreading to "off" (unchecked).
