What's New
Miscellaneous and Important Changes
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
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
Known Issues
- 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
- Interactive Render Regions may require adjustment to start rendering
- Rewiring subnet indirect inputs
- Auto camera creation for IPR
- RenderMan clipping planes
- If a light instance's master is disabled, the first render/update will still show the master
Known Limitations
- Tractor Integration
- Rendering with Mantra lights not possible
- Bypassing shader nodes
- Rendering with Houdini VOPs
