Update 3 of the Houdini Engine for Unreal for Houdini 20.0.
The plugin is now linked to Houdini 20.0.688 / HAPI 6.2.0.

Source and binaries are included for:
UE5.2, and UE5.3 on Windows, Mac OS (intel and Apple silicon).

Please note that the source code available in the 5.0 branch is compatible with UE 5.0, 5.1, 5.2, 5.3, and 5.4. Binaries for UE5.4 will be provided in the next release - as the plugin currently compiles but is untested with 5.4.

Also, please remember that the plugin's binaries AND source code are always available with the launcher/installer for a given version of Houdini. If you install or want to use a daily build of Houdini, please use the version of the plugin binaries/source code included with it.

New features / Changes:

• Added support for Unreal 5.4.
  As mentioned above - the 5.4 plugin compiles but is currently not fully tested.

• Added support for the plugin's content examples.
  The content examples are available as a content plugin that can be downloaded on their git repository:
  https://github.com/sideeffects/HoudiniEngineForUnreal-ContentExamples

• Added support for baking outputs to a single actor rather than multiple actors.
  This is controlled by a setting in the Houdini Asset Component next to the bake setting.

• Added support for baking of geometry collections.

• Added buttons for selecting the temporary cook folder and bake folder.

• 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

• Improved the logic used for finding uproperty attributes.

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

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

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

• Nanite FallbackTargets are now automatically set for given Nanite Fallback Values.

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

Bug Fixes:

• Button strip parameters now work correctly in the details UI.
• String parameters with the tag "unreal_ref" have an updated UI in the details view which matches the native UE5 object picker.
  They previously missed buttons to navigate to the currently selected object and it in the Content Browser.
• Fixed an issue where proxy meshes would not have Unreal's color-per-vertex gamma correction applied.
