I am trying to make a procedural escalator HDA. So far I have the base mesh working but I need the curve driving the geo to be baked as a spline in UE4 so I can use it to animate the steps along it.
According to the docs I can set an attribute to output the curve?
In Version 2, you can output a curve from your HDA as an Unreal Spline Component.
To do so, you simply need to add the unreal_output_curve int attribute to the curve, with its value set to 1.
Where do I set this attribute as the curve node in Houdini has no flag entry to set this? I tried adding an attribute wrangle but no luck.
Currently when I bake the curve actor that is set as an input it is giving me strange results. I just want the editable curve node that is driving the geo be turned into a UE4 curve.
In an ideal scenario I could use the HDA in a blueprint and expose the curve as a spline but I'm not sure that's possible.
Thanks in advance!
Cheers, Rob
