• We now disable checkpointing when ipr IPR rendering
• Added correct pixel filter settings globallyAllow a coordinate system with Null node

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
• Allow/Fix point, vector, matrix, normal osl parameters to render correctly
• Correctly reverse NURBS orientation

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
