Fixes foliage import crash when importing foliage into World Partition levels.

Fixed a build issue for the HoudiniEngine Unreal plugin that occurred on some Linux platforms.

Data Table HDAs imported into Unreal now have UI showing the generated data table as well as the row struct used.

Changed the %purpose auto collection to be slightly slower when doing a full scene traversal, but enormously faster when using it in conjunction with other pattern elements that restrict its traversal to only part of the scene graph.

The unreal_datatable_rowstruct attribute that is generated when using a data table as geometry input has been renamed to unreal_data_table_rowstruct. Allow Houdini assets that output point clouds to be added to Unreal. When such an asset is added, it will generate a data table using the attributes of each point. The Houdini point clouds generated by data table inputs can be imported back to Unreal in order to generate the original input.

Fixed a crash when baking HDAs that generate Unreal Instances.

Fix a bug where Houdini editor node metadata could be written out to USD files if it appeared on a top level variant selection primitive.

Prevent python exceptions when right-clicking a USD primitive in the scene graph tree with invalid "editor node ids" in its metadata.

Added the ability to output a particle radius attribute in the FLIP DOP Source SOP.

Added the reloadseq HScript command to reload the image sequence in mplay.

The Pyro Solver SOP will no longer attempt to interpolate its data at non-integer frames.

• Fixed a bug that caused the output details UI to show the previously refinedStaticMesh after the HDA was recooked, and a new ProxyMesh was used instead.The output UI was displaying a "Bake" button instead of a "Refine" button, andpressing that Bake button would actually Bake the previous SM instead ofrefining and baking the newly generated proxy mesh.
• Houdini Indie: Fixed a bug that caused the Input/Param/Handle UI to be displayedempty, with the Indie license warning even if no Inputs/Parms/Handles are present.

Fixed the Display Origin flag on objects so that the axes aren't double transformed by the object transform.

Fixed a potential deadlock loading Alembic archives.

Allow specifying two pieces of custom data for the Houdini GL render delegate in the UsdRenderers.json config file. "lighttypes" is a list of hydra sprim types that should be treated as lights. "pointinstancertypes" is a list of USD primitive types that should be treated like point instancers when doing instance selections.

Fixed an issue with the lock flag icon obscuring work item dots on TOP nodes. The flag decoration popup will no longer appear when mousing over the work item dot display.

Fixed a bug with viewport drawing of volumes when Volume Quality was set to High. This bug could cause parts of the smoke to disappear.

Fixed a crashing bug with the USD Unpack SOP in "Output Polygons" mode.

Added hou.contextOptionChangeCallbacks method to return the list of currently registered context option change callbacks.

Fix potential crash when using VEX code to access node parameters that use python to access information from a LOP node.

Added proper type conversions when using a data table as geometry input for Houdini assets. Numeric types, vectors, rotators, transforms, and colors are now converted into a corresponding Houdini number or tuple.

Fixed an issue where the Houdini Engine for Maya plugin could fail to find libHAPIL in certain situations on macOS and Linux.

Fixed a bug in the modify point instances LOP where incorrect IDs were being generated when using "internal SOP" sourcemode and ids were present on the point instancer.

Fixed an issue where HARS could fail to start on certain machines without preloading libc_malloc_debug.so.0
