Houdini now gracefully handles Alembic attributes with an array extent of zero.

Fixed an issue where importing meshes could create empty mesh sections.

Fixed stale instancer output data not being properly cleaned up upon cooking. This issue could cause level data to bloat unnecessarily.

Fixes: #124444

• Added support for specifying the material slot when using the unreal_material attributewith point instancers (unreal_instance). You can specify the material slot to override byadding its slot number to the attribute name: unreal_materialX.
• When importing meshes to Houdini, we prefix the unreal_material attribute string with thematerial slot index if the mesh uses more than one materials.This prevents the plugin from merging material slots that uses the same material.
• Imported material parameters now also add their material slot number to the attribute name(unreal_material_X_PARAM_NAM). This prevents overwriting values when separate materials usea material parameter with the same name.

Fixed all foliage types being removed when an HDA is added

Fixed HDA foliage not working with World Partition.

Fix tiled rendering in husk when a data window was authored on the render product.

Fixes a bug in the Modify Point Instances LOP which would error when deleting instances if the instancer had non-array attributes.

Added support for multiple foliage actors in Unreal 5.0 when World Partition is enabled.

The Performance Monitor now reports statistics for rendering ROP nodes.

Fixed a crash when subd mesh's boundary interpolation rule is set to "none".

Fixed a bug which broke hiding point instances with the Modify Point Instances LOP.

Fixed a bug that caused loaded curves to disappear after being recooked (but not the first one!).

• Fixed warnings in UE5.1 due to the deprecation of ANY_PACKAGE.
• Fixed _GetEditorStyle() build errors on non-pch builds.

Fixed bug in the Unreal Engine plugin that would cause incorrect material assignments on high poly count mesh inputs.

• World inputs now add the "unreal_level_path" and "unreal_actor_path" whensending their input objects as references.
• Fixed issues when rebuilding assets that uses other HoudiniAssetComponent in World Inputs.
• Fixed automatic mesh refinement when Playing In Editor not working in UE5.
• Fixed HAC returning incorrect bounds, this caused issue when framing ('F') the HAC.

When manipulating a camera locked to the view, we no longer require the camera's "editor node" to have "control" parameters. Just "t" and "r" parameters are sufficient.

Fix landscapes not being shared when importing landscape tiles in World Partition Levels.

Added landscape streaming proxy name attribute when exporting to Houdini.

Fixed a bug that could cause a parameter's HAPI_ParmInfo.invisible and HAPI_ParmInfo.disabled flags to be out of date when calling HAPI_GetParmInfoFromName.

Fixed a bug that would reset the input names of the Subnet Outputs VOP and the output names of the unlocked Subnet VOP HDAs when saving the HDA.

Karma now properly saves the pixel aspect ratio to metadata in deep exr files.

Fixed houdini-generated materials remaining in the temp directory after baking their corresponding meshes.

Prevent python exceptions when inspecting a viewport instance where the instancer primitive isn't a standard USD point instancer.
