New Features in 23.6

Fixes

• Motion Blur Fixes

...

• :
  • For Maya
   fix for motion blur on maya
  • curves created with the curve tool (different from hair)
•  Fixed a bug where light filters from referenced maya scene files with namespaces were getting ignored due to not using the handle that's fixed up for prman
• Pixel aspect ratio was being ignored for preview/IPR renders.
• • .
  • For a
  Fixed a bug where motion blur would fail for a 
  • blendShape that had its "origin" attribute set to "world" rather than "local".
  Fixed a bug where motion
  • For when blur would revert to frame-open style when
  motion blurred
  • mesh was edited during IPR.
• Avoid issue when building against maya2019 headers, where on linux /usr/include/X11/X.h gets pulled in and redifines "CurrentTime", which happens to be the name of a method in one of our classes.
• Fixed a bug where light filters from referenced Maya scene files with namespaces were being ignored.
• Pixel aspect ratio is no longer ignored for preview/IPR renders.
• Fixed a bug where only FIXED: Only the first xgen instanced archive was output to the renderer.
• Fixed a bug where PxrCryptomatte sample filter could pick up the wrong camera substitution for the <camera> variable in its filename.
• Denoising with mayabatch now works as expected.
• Fixed a bug where some array parameters with indices greater than 9 would fail to export.

Miscellaneous

• RfM translation Translation of mayaMaya's image planes now respects the "Use Image Sequence" checkbox, and the "fit" of image planes is translated accurately.
•  For RfM command line rendering, added Added a -par arg argument for the Render command for setting pixel aspect, named the same as maya's.
• Namespaced alembic nodes are now automatically associated with a set of similarly namespaced materials.
• rfm now processes Now process standard extension attributes on custom transforms.

• Allow multiple instances of a procedural primitive to exhibit different random variations. We added Added a per-instance "user:procprimid" attribute that can be used by patterns to compute a globally unique attribute.

• Add Added a new -velocityscale flag to the procedural to scale velocity primvars used for motion blurring.  - Add Added velocity scaling control to gpuCache node.

•  implement Implemented AOV import/export and basic AOV overrides.
• When "Omit defaulted attributes" is enabled, RfM will omit the "maxdiffusedepth", "maxspeculardepth" and "relativepixelvariance" attributes in RIB archives, if they are set to their default value, so they may be overridden.
• RenderMan for Maya now supports the parentOffsetMatrix attribute on transform nodes.
