• Added support for setting the CenterAdjust property on a Spline Segment Mesh.

Added a new Log Command: Houdini.DumpGenericAttribute This can be used to list all properties/generic attributes for a given class, listing the expected unreal_uproperty_XXX attribute names and types, and if the system supports it. Usage example: Houdini.DumpGenericAttribute StaticMesh

Changed options for exporting layers from Unreal to Houdini to allow more control over which landscape layers are sent.

String parameters with tag "unreal_ref" have an updated UI in details view which matches native UE5 object picker, which previously missed buttons to navigate to the currently selected object and to use the currently selected object in the Content Browser.

Button strip parameters now work correctly in the details UI.

Fields in parameter UI will now remain focused after a HDA is cooked, making it possible to edit and navigate the Unreal details UI using keyboard only.

Improvements and bug fixes for ramp parameter details UI. Ramp curve editor can now be opened in an external window for easier use.

Added support for baking of geometry collections.

Fixed an issue where proxy meshes would not have Unreal's color-per-vertex gamma correction applied.

Added support for "Horizontally Join to Next Parameter" option to Details UI.

TOP nodes and networks in PDG details UI are now lexicographically sorted.

Fixed a crash when cooking if an HDA input straddles a world partition boundary.

Fixed a crash during cooking if an HDA input straddles a world partition boundary.

Limit the number of Landscape Splint control points input from Houdini to Unreal to 1000. This prevents a crash in Unreal when saving a map with a high number of control points.

Limited the number of Landscape Spline control points input from Houdini to Unreal to 1000. This prevents a crash in Unreal when saving a map with a large number of control points.

• SkeletalMesh input now send two packed prims to the HDA input:the mesh data (mesh, colliders, LODs, sockets) as `Base.shp` and thecapture pose data as `Base.skel`.
• Updated the UnrealToKineFX HDA to split/unpack the new SkeletalMeshinput data.
• Fixed scale on the Skeletal Mesh input Capture Pose to match FBX imports.
• Fixed unreal_skeleton attribute value for AnimSequence inputs.

• Added access to bImportAsReferenceRotScaleEnabled, bImportAsReferenceBboxEnabled,bImportAsReferenceMaterialEnabled, bExportMaterialParameters to the Input Wrappers.
• Inputs - the default value for bPreferNaniteFallbackMesh and UnrealSplineResolutionsnow respect the default value set in the plugin's settings.
• World Inputs - Added access to bDirectlyConnectHdas, bExportEditLayers and bExportPaintLayers.

Added a new attribute unreal_landscape_layer_normalize to control landscape normalization. Fixed deprecrated non-weight layer attribute using edit layer instead of target layer.

Added a new attribute unreal_landscape_layer_normalize to control how layer data is normalized if outside the range 0 to 1. By default is it clamped, setting 1 will normalize the data. Changed depcreated weight layer blend to use Target, rather than Edit, layers.

Fixed world input objects not being properly created in Houdini when invalid characters are present in the actor or component's name when using the new input system.

Fixed an issue where Houdini Static Mesh components would not be deleted when recooking.

Fixed an issue where collision-only meshes were still visible in the scene.

Fixed issues when translating Houdini materials to UE materials:

• Diffuse values were incorrectly used for specular.We now properly use "reflectivity" for specular value/maps.
• Fixed the diffuse map sometimes being used for normal maps.
• Fixed emissive/metallic values not being properly created.

Added more control over which landscape layers are sent to Houdini from Unreal. The user can now specify if Edit Layers and/or Paint Layers can be sent to Houdini. Removed the previous option to send the combined height-only data, as this can be acheived by disabling Edit and Paint layers simultaneously.

Deprecated Raw Mesh generation method. This will remain the default method in 19.5 to maintain compatability but will be removed in a future version of Houdini.

Don't create layer info objects for Landscapes where the layer is not specified in the HDA. Don't copy user specified layer info objects to the bake folder.

Don't created layer info assets for landscape material layers if they layer is not present in the HDA. Do not copy user specified landscape layer info objects to the bake folder.

• Fixed an issue with baking foliage where material overrides would be lost:material overrides are now applied to the cooked foliage type instead ofdirectly on the instanced foliage components (component level overrideswere lost if any modification was made to the foliage type that resultin an update to the components).
• If an HDA outputs foliage via an existing foliage type asset(`unreal_instance` is set to a foliage type asset and not a static mesh),then baking will bake to a new foliage type asset if the cooked foliagetype has been modified (for example, generic uproperty attributes areused to change properties of the cooked foliage type, or materialoverrides are applied).

• Fixed an issue where the static mesh and materials used by a foliage typewas not baked when the foliage type was baked.
• Baking now also checks if a temporary asset was created by the`HoudiniAssetComponent` that is being baked (using the GUID saved in thetemporary asset's metadata) before baking the object itself.

Added support for tokens in bake outliner folder attribute.

Added support for tokens when specifing the bake world outliner folder.

• When baking a skeletal mesh the skeleton is now also baked if theskeleton asset is a temporary output.
• Skeletal mesh output and baking now supports output attributes, such as`unreal_temp_folder` and `unreal_output_name`.

Skeletal Mesh input now exports the mesh using the `FSkeletalMeshImportData` (the source geometry), if available in the bulk data, to Houdini via `FMeshDescription`. This also fixes an issue where Skeletal Mesh UVs were not exported to Houdini correctly.

Fixed an issue where vertex colors would not be converted from gamma to linear when importing to Houdini from Unreal.

Fixed vertex colors not being converted to linear space when importing from Unreal.

Added checkbox to export height only when importing to Houdini from Unreal.

Baking outputs from a HoudiniAssetComponent will no longer replace assets when both of the following conditions are met:

• The default bake name is being used (for example, no custom name has beenset with unreal_output_name),
• and it is the first time that the HoudiniAssetActor is baking thespecific output object.

• The default bake name is being used (for example, no custom name has beenset with unreal_output_name),
• and it is the first time that the HoudiniAssetActor is baking thespecific output object.

When baking an output asset the default bake name now includes the `HoudiniAssetComponent`'s GUID (if a custom bake name was not set in the output details panel or via attributes).

This makes the default bake name unique to that specific HoudiniAssetActor, preventing situations where baking could replace assets baked from different instantiations of the same HDA from different levels when using the default bake name.

• Fixed an issue (in the new input system only) where world inputs hadincorrect transforms for the input geometry generated from its componentswhen "Keep World Transform" is disabled.
