The RBD Cluster SOP now has an option to fuse the clustered pieces together.

The Cloud Light SOP has been updated to use modern Block For Each SOPs.

Unity plugin: Moved out HEU_PartData.GetInstanceOutputName into HEU_GeometryUtility. Moved out the LOD transitions array into HEU_GenerateGeoCache. Added support for loading regular mesh geometry and part instancers for HEU_GeoSync, and therefore indirectly to HEU_PDGAssetLink.

Fixed bugs homing/framing with objects using point or dop instancing.

Agent Procedural no longer changes names of objects when rendered with verbosity level above 1, which could affect trace scopes and cryptomatte name layers.

Fixed a crash that could occur when disabling and then re-enabling a SOP solver.

Limit the skinshadercore VOP to being used in the surface context.

This should fix any errors and warnings related to the contents being included in displacement shaders. It was previously possible for this to happen when the VOP was assigned as a shader directly, without explicitly piping into a surface outputs VOP.

Fixed bug where changing levels in the viewer would cause an older state to be entered rather than the last one the viewer was in at that level.

Fixed errors with the attribute dropdown menus and paint buttons on the Guide Groom and Hair Generate objects.

Fixed a packed primitive crash in the viewport during an incremental update after revisiting a SOP which previously displayed it.

Added optional tag parameter to hou.undos.add() method so that the newly added hou.undos.removeUndos() method can invalidate and delete all existing python undos associated with said tag.

HDAProcessor now uses @pdg_name rather than @pdg_index for its default output file name.

Fix missing data dependencies in the View Dependencies dialog for VEX and Python nodes.

Fixed a bug where pdg_name would resolve to empty string.

Fixed potential darkening artifacts with GGX BSDF when there's severe discrepancy between shading normal geometry normal.

Enabled construction plane support in the ortho viewports.

Changed the look of the ortho grids to better match that of the reference plane.

Added a new constructor to hou.AgentShapeLibrary that loads the shape library from a hou.Geometry.

Fixed an issue where the Bullet solver's impact data was recorded with the time at the end of the DOP timestep, rather than the substep that the impact occurred on.

Changed the default of the Sequence Index parameter of the File SOP, when loading as a Packed Disk Sequence, to an expression that is less prone to problems with a non-default Frame Range start.
