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.


 

What's New


Miscellaneous and Important Changes 

  • Added a new "prevent polygon cracking" on the displacement section of Maya meshes. This will prevent faces from separating during displacement, as long as the displacement pattern is continuous across faces

  • In batch mode, rfm now txmakes all needed textures using multiple workers before the render starts
  • Some RenderMan object attributes are now available in the channel box for mass editing
  • The Attribute Editor's Help menu will now open the current node's documentation page (instead of jumping to Autodesk's server). A 'rfmDocsRoot' optionVar can also be defined to point to a local RenderMan documentation server. See doxygen documentation for details
  • colorOffset is now taken into account on Maya's ramp node
  • Added shelf menu options to create volume primitives (box, sphere, cone). Right-click the volume icon to access them

Fixes

  • MASH networks which contain a MASH_Dynamics or MASH_BulletSolver node now behave as expected

  • Alembic: Normals and facevarying primvars are now rendering correctly
  • Fixed incorrect string tokens expansion on frame 0
  • Fixed an issue that caused two frame sequences to not denoise when "crossframe" denoise was requested
  • Fix possible crash when dumping RIB
  • A bug that caused Xgen to fail when using more than two motion samples for motion blur has been addressed

Developer Documentation

You can find a useful Doxygenated developer documentation in the Developers' Guide under RfM2

Known Limitations

RenderMan for Maya

  • Light Linking volumes is not currently supported
  • _pref references for Alembic caches 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

     

    Xgen : Xgen will crash during live rendering unless you set Window > Preferences > Xgen > Multithreading to "off" (unchecked).
