[vellum] Enable Self Collision for 1 of 2 merged geos Jan. 15, 2019, 2:32 p.m.

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.

[vellum] Enable Self Collision for 1 of 2 merged geos Jan. 15, 2019, 11:36 a.m.

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?

Enable Vellum attribute on specific frame Jan. 11, 2019, 12:50 p.m.

Hi
Using a Paint SOP to enable a Vellum collision attribute on part of my collision geometry.
disableexternal =1

but I only want this to occur after a specific frame in my sim.

If I'm using Vellum in SOPs, how can I accomplish this?
