Miscellaneous and Important Changes 

• Various UI changes and improvements

• Added camera projection sweep parameters

• Added holdout shelf and menu tool for creating holdout geometry and setting up shadow AOVs

• Render cameras now available in subnets
• Geo/xform motion sample parameter overrides on obj nodes are now interactive
• Move "enable depth of field" toggle behavior to ROP node
• Object paths now evaluate expressions
• Support added for custom versions of pxr nodes with name scope::namespace::pxr*::version
• We now support sparse RenderMan parameters
• RfH now drives fovEnd from standard camera parameters
• Users can set env variable searchpaths
• Users can override pixel filter for id, sampleCount, cpuTime, id, and z AOVs
• We now always emit defaults for unchanged parameters
• Added bake render menu tool, ROP button, and now prevent IPR renders from starting while baking
• The texture manager now rejects files with unknown extensions. A warning will be output with the file name
• Visibility SOP nodes are no longer respected by RenderMan, since they are intended to affect viewport visualization
• There is now a "Round Curves" setting in the spare RenderMan settings.  Curves with normals render as ribbons, and this setting has the effect of ignoring the normals
• Add Spare Parameters have been reorganized

Fixes

• Fixed forced matte and phantom to render regardless of candidate membership

• We now output AOVs with shelf render button

• A bug that prevented meshes with multiple shaders from rendering when deformation blur was on has been fixed

• We now respect pixel aspect ratio
• Ptex support (for quads only) fixed
• Fixed overwriting VDB files on disk
• Fixed a bug where Houdini scenes with hair would sometimes crash

• An issue where preview renders in the preset browser were not working has been addressed

• We now only write non-default shading parameters
• No longer update render when changing folders
• NURBS curves were being converted to linear, and now they're rendered directly, so should appear smooth

• A bug preventing exporting materials that had PxrSeExpr nodes inside has been addressed

• A bug that caused importing of RfM presets that contained ramps using the preset browser to break has been fixed

• Fixed a bug where the optional RMAN_RIXPLUGINPATH environment variable was not being looked at when loading args files during RfH startup
• Fixed a bug where osl structs used in conjuction with the special vstructmember tag "<paramname>.Struct" weren't establishing expected struct to struct connections when translated to RenderMan
• Fixed a batch rendering bug where first frame was missing motion blur
• We now correctly write float array instance attributes
• Fixed a bug where motion blur was not applied with SOP was not time dependent
• The Dicing Reference Camera now works as expected.  It's available under RenderMan/PrimVars/Dicing PrimVars that can be added to geometry nodes

• Selecting "point velocity attribute" for Point Motion Blur on point instances should now work

• Preset Browser

  • Fixed configuration-specific incorrect scaling of menu fonts in the preset browser
    

  • Fixed incorrect gamma correction of preset browser preview renders
    

  • The preset browser will now correctly generate a preview image when saving a light rig
