- Fixed bug that did not read time correctly to expand $F in string paths.
- Fixed bug where curves with certain bases would look wrong when motion blur was enabled and "width" was defined.
- In Solaris -
- Fixed a bug where hdPrman would always specify the first field of a vdb file as the density field.
- Fixed a backdoor workflow where display and sample filters are allowed to come through Hydra as shading nodes.
- Fixed the "Render to MPlay" and "Render to Disk in Background" buttons on the RenderMan LOP.
- Light groups now work in light path expressions (no light selects).
- Fixed a crash that could occur when running in the usdview that ships with Houdini if the camera was not created with Solaris

Miscellaneous
add Added support for pre- and post- render hooks via RFHhooks.
- bringing back PxrDebugShadingContext hda
Known Limitations
- Brought back PxrDebugShadingContext VOP/
- Improved motion blur support for in Solaris:
Motion blur for meshes, curves, and point particles is now supported.
There is now a Motion Blur tab under the RenderMan Master Attributes on Render Geometry Settings node.
Velocity blur and enabling/disabling motion blur for objects is now supported through the Render Geometry Settings node.
- Enabling/disabling motion blur works for transforms and geometry.
Other changes in Solaris:
- The camera now tumbles around the mouse cursor when rendering in Solaris.
- Added baking options to the RenderMan LOP under the Rendering/Render tab.
- The RenderMan render is now paused when the user switches to the GL renderer.
- RenderMan's Xcpt messages now go to stderr. They were sometimes getting lost in Solaris.
Removed xform_motionsamples and geo_motionsamples from the RenderMan tab because these are not RenderMan-only parameters and were affecting Mantra renders. Now you must manually add if you want to set these parameters on the object.
Added support for shop_materialpath in alembic attributes, but the material must be included in the RenderMan scene for the procedural to apply the material. Added a bundle parameter on the RenderMan ROP to force material export.
- Improved viewport lighting.
- Read abcvelocityscale attribute to scale alembic velocity.
- Added acceleration blur support.
