The Karma Fake Caustics VOP is no longer necessary, as Karma does fake caustics by default now. This node should be removed from materials.

The Instancer LOP now converts Alpha SOP data to primvars:displayOpacity, matching the already-existing Cd -> primvars:displayColor conversion.

When SOP Import is creating a point instancer, Cd and Alpha are now translated into primvars:displayColor / primvars:displayOpacity instead of remaining as primvars:Cd / primvars:Alpha. This now matches the Instancer LOP's behaviour and is consistent with how other primitive types are imported.

The Vellum Solver's Velocity Damping parameter now properly respects both Time Scale and Global (DOP) Substeps.

XPU: Fixed a bug with attributes (including UVs) being evaluated distorted on n-gons that are not subdivided but have displacement.

The Open Subdiv subdivide SOP with T-junctions will now convex the same way as the Divide SOP so should avoid cases of missing polygons or wrong-sided polygons. This will change the vertex/primitive order coming out of this SOP.

Shaders using Mtlx Height to Normal nodes may appear slightly different.

When using services or farm schedulers that use the MQ server, the local Houdini session will not be able to connect to an older version of the MQ Server or communicate with farms using older versions of PDG. The latest version the MQ Server packaged with Houdini 20 is required in order to connect. The farm must also be updated to use the latest version of PDG.

Removed the legacy QuickTime export option in Mplay on macOS. Users should use the new FFmpeg exporter instead as it has more features and options.

Attribute Copy SOP will always copy the attribute even if the source or destination groups are empty. This ensures the attributes are created on empty geometry and detail attributes are always copied.

The Convert Line SOP will now interpolate attributes and groups from the input geometry.

The HeightField Pattern SOP now uses streak border conditions for post-blur rather than the volume's native type. This will have better results for masks. To get the old behaviour, turn off post blur and use an explicit heightfield blur afterwards.

Changed the behavior of HQueue jobs so that they always inherit the conditions set on their root jobs in addition to the conditions on the jobs themselves. Previously, jobs only inherited their root jobs' conditions if the jobs did not have any conditions on their own.
