What's New
Interactive Rendering
Now you can render through all stages of your pipeline! From modeling to final renders, RenderMan is designed to give you immediate feedback from inside Maya. By skipping the export of a scene to RIB, artists can get an immediate look at their work in full ray traced mode and continue to interact and make changes without needing to restart the render.
Render to Viewport 2.0
Render to the same window where you work! Move objects, make modeling changes, add and alter materials and lights, even import and update asserts without needing to stop the render. RenderMan becomes your viewport at all stages!
Interface Simplification
Better organization, smart exposure of options and attributes, and more-native workflows mark this iteration of the RenderMan for Maya plugin.
Per-face assignments
Added per-face shader assignment for SubDivs and Polygon meshes
Miscellaneous and Important Changes
- Imported older PxrDomeLights will now be reversed. To correct this, remove the negative scale from the X axis.
- TCL has been removed
- INI files are now in JSON configuration
- The projection editor is removed, native Maya projections are supported.
- Alembic Workflow relies on the standard Maya Cache menu.
- Dynamic Rules have been removed.
Older Maya scenes that had PxrRamp nodes in it may break. To fix, you can run this python script in the script editor --
Code Block import rfm2.utils.scene_updater rfm2.utils.scene_updater.update_pxrramp_nodes()

Improvements since RenderMan 22.0b1
|
Known Limitations
RenderMan for Maya
- 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.
Alpha Limitations for RfM - These are expected to be resolved before release
Xgen will not reflect changes in the Collection
Cancelling a preview render may stall Maya
Dicing cameras
You must manually set a displacement bound in RfM on the shape node or RenderMan will not calculate displacement.
Maya Dynamics, various bugs remain.
Render selected objects only not yet supported
Texture Projections do not render correctly.
View statistics, remaining issues to resolve
Material assignment to archives (RIB Archives, Alembic archives)
Alembic procedurals render incorrectly
Stereo cameras do not render
Denoise workflow is not available
Checkpoint + Recovery not available
PaintFX
Holdouts not available
Baking not available
Clipping planes not available
