RenderMan for Maya Release Notes
Lightyear © Disney/Pixar
Welcome to RenderMan for Maya 25!
This new release of RenderMan for Maya 25 (RfM) continues to support the full RenderMan feature set. See the RenderMan Release Notes for more details about RenderMan itself.
This current release offers support for:
Maya 2023
Maya 2022
Maya 2020
What's New
The new denoiser uses the same workflow as the old denoiser when spooling jobs for rendering.
There is a new UI for the denoiser under the RenderMan → Tools menu
By default, new volumes in your scene are added to the default volume aggregate set named "globalVolumeAggregate", which is a global node that will work with importing and referencing.
Developer Documentation
You can find a useful Doxygenated developer documentation in the Developers' Guide under RfM2
Known Limitations - New
Maya 2024 is not supported
Known Limitations - Existing
Deselecting "Receive Shadows" does not work.
Light Linking volumes is not currently supported
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
Maya Fur Feedback is not supported
On Windows, jobs running mayabatch will hang at the end if Autodesk's mtoa plug-in is loaded. This can be avoided if you unload mtoa, change it to not autoload, and resave the scene without Arnold dependencies.
