I'm testing a few things using Houdini's hair tools. Is there a way that I can have two sets of curves from an external program. 1 set is a reduced set of guide hairs, say 200, that can then drive a another higher curve count set of curves? Hair Gen lets me set the area of influence for guides, and generate interpolated hairs. Wire deformer allows me to deform one set of curves with another. However, I need the guide hairs to affect the larger set in a way more similar to how instanced hairs are generated. Triangulate the closest guides and weight them based on the proximity to those three guides.
This is basically to simulate a smaller subset of guides and then cache out a predetermined larger set of curves, rather than generate them via Hair Gen. Any thoughts?
