Welcome to RenderMan for Houdini 22!
This release of RenderMan for Houdini 22 (RfH), includes a number of new features to address feedback as well as many improvements to RenderMan for Houdini workflow and performance.
- Rendering with RenderMan will not operate on Houdini Apprentice editions, see Side FX's website for options that allow Third Party Rendering
- Houdini Indie is only compatible with 17.5, you must be using at least version 17.5.210 or higher
RfH supported platform for version 17.5 is now build 17.5.360 for 22.7+
What's New
- Allow a coordinate system with a Null node
Miscellaneous and Important Changes
View RIB tools for debugging added
- "View Selected RIB" menu tool only works in versions of Houdini 17.5.229 and later
- Added interactively edit hider:minsamples, hider:maxsamples, hider:minextrasamples, and Ri:PixelVariance
- Support added for vector3, vector4, matrix4x4 parameter tags
- We now disable checkpointing when IPR rendering
- Added correct pixel filter settings globally
Fixes
A bug that prevented the use of DWAa and DWAb EXR compression has been addressed
- Fix extraneous warnings created when rendering motion blur on alembic geometry imported into Houdini
- Bug fix pxrshadowsamplefilter Shader Type = output
- Fixed a bug on Linux where Houdini could crash if rendering to 'it' after having rendered in the Render View
- Fixed a bug that did not unhide geometry when subnet became visible
- Mesh light bug fixes including issues with referenced geometry
- Fix sun direction manipulator to prevent invalid directions
