• 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.
