Hi
Have a Vellum network with 2 pieces of geometry draped separately, then merged and input to a single Vellum Solver.
The problem is that I want ‘Self Collision’ to be only enabled on 1 of these merged geos.
How would I accomplish this?

Same answer as previously

Thanks.
Someone much more knowledgeable than myself pointed out that the issue is that Vellum cannot distinguish geo at a more granular level than ‘self’ and ‘external’

Ended up doing 2 separate solves and merging AFTER the simulation. Not ideal but in my case I can get away with it because my Layer0 clothing hugs the surface of my collision geo and doesn't really interact with the Layer1 clothing.
