I am trying to make a track lighting tool for Unreal using Houdini. It takes a curve from Unreal, extrudes a track and places lighting fixtures along it. I saw in another post that instancing lights is not currently a feature. I am wondering if there is a way I can instead mark points in the generated model with some kind of label. And then I would use a construction script in Unreal that instantiates the lights at every labeled point generated by the Houdini asset. What is the best way to mark the points in the Houdini asset and read those positions in Unreal?
Thanks.
