• RenderMan for Houdini now supports rendering packed USD primitive geometry nodesgeometry within the geometry context.

Fixes

• Fixed an issue with parameters with unknown widget types still being added to hdaFix a bug that would cause interactive rendering to crash when modifying materials or the timelineFixed a crash when merging vdbs
• Fixed logging bug when using the preset browser with textures
• A bug causing importing and exporting shader networks with PxrOSL shaders to the preset browser has been fixed
• A bug causing importing and exporting nodes with arrays to the preset browser has been fixed
• We now export packed alembic string attributes as customer user attributes
• Numerous bugs and crashes when using instancing have been addressed
• Address an issue when the preset browser would not import material assets with textures correctly
• Fixed a bug where primvars are dropped when material is applied on SOP
• Fixed some motion blur bugs with packed geoFixed an issue to update timeline edits for parameters of light source an issue preventing render updates for keyframed parameters on light shaders
• Fixed an issue that would prevent a interactive render from stopping if an abort was issues in the "it" display
• Fixed an issue that would cause was causing the IPR Render shelf button to emit a final render instead of an IPR renderFixed a crash when instances would be created from points out of a POP or DOP nodetool to read the ROP display rather than always starting an IPR session via MPlay or "it"
• Fixed a bug that could cause Pixel Filter mode to remain pinned to "importance"
• Fixed a bug that would cause interactive rendering to crash when modifying materials or the timeline
• Packed Geometry:
  • Fixed a bug where unpacked primitive geometry would not get material attribute applied
  • Fixed a bug where velocity motion blur was not applied when packed SOP was not time-dependent
  • Fixed
  a bug where unpacked primitive geometry would not get material attribute applied
  • some motion blur bugs with packed geo
  • We now export packed alembic string attributes as user attributes
• Instancing:
  
  • Fixed an issue to more closely match Mantra behavior when ptinstance = off
  • Fixed a crash when instances would be created from points out of a POP or DOP node
  • Numerous other bugs when using instancing have been addressed
• Preset Browser:
  • Fixed logging bug when using the preset browser with textures
  • A bug causing importing and exporting shader networks with PxrOSL shaders to the preset browser has been fixed
  • A bug causing importing and exporting nodes with arrays to the preset browser has been fixed
  • Address an issue when the preset browser would not import material assets with textures correctly

Miscellaneous Changes

• Bxdf output type changed to surface to allow Bxdf inputs

• oslbuilder now shows up in PxrMaterialBuilder
• Added support for ptmotionblur="deform" on Instance OBJ
• Added RFH_USER_LOG_DIR, RFH_USER_OTLS_DIR, RFH_USER_PREF_DIR
• Reorganized ROP for illumination baking options
• The "darkfalloff" option has been added back to the adaptive sampling options
• Added biasR, biasT, rawId, and dPcameradtime AOVs to LOPs, ROPs, and TOPs
• Parameters with unknown widget types still being added to hda with a default UI.

Known Issues

• Display edits cannot changed bechanged from the image tool to mplay
• Cross-frame denoising pdg support
• Phantom objects are removed from all rays, not just camera rays
• Applying undo of deleted nodes or collapsing to subnet may not work as expected
• Rewiring subnet indirect inputs
