Additional examples on how to correctly output a curve from a Houdini asset to unreal

[geralyssia]

Hi, I tried to use the engine with the HoudiniPCGTranslator to output a Houdini curve from the Houdini asset into unreal. I followed the example from the Houdini HoudiniMassTranslator, where the Houdini asset:

• ingests unreal splines
• process it
• outputs mesh and zone shapes.
  From the example, it's not clear to me what are the zone shapes. From the Houdini side, they look like curves, however, in unreal I can see the created components but all of them have zero points assigned to them. For my testing, I need to be able to output the curves back to unreal in a way that they can be later used by my blueprints (and preferably visible).

Hi @geralyssia, I have added the unreal spline output functionalities v2025.03.02
Replace the HoudiniEngine plugin folder with this, and check the version Fab. 11 2025 in Unreal.

Now houdini curves will output as unreal SplineComponent without any additional attribute, and you could even use s@unreal_output_spline_class attribute to specify your own blueprint that contains a SplineComponent.

Hi, @ChildAdrian, thank you very much for the enhancement! I’ve tested it, and everything works as expected.
I truly appreciate your support and effort in improving the engine’s functionality.
