I am working with several individual strands (curves) that I have duplicated in mops and resampled. I am doing some vellum hair sims
that I later pop in to copytpoints, and I noticed after the vellum config hair the number of points have doubled, so I have overlapping objects (on the copytopoints). Any reason for that?

thanks

If you're trying to copy preconfigured Vellum objects with constraints applied, the easiest way to do this is to do your initial Vellum setup with constraints, then use Vellum Pack to wrap everything into packed prims, then use Copy to Points or MOPs or whatever you want to create the duplicates. Then use Vellum Unpack prior to simulation.
