Hey everyone,

I am having a problem. I am tasked with simulating a miniature knitted fabric. For that purpose i am creating a Vellum cloth simulation to drive movement. The cloth has to be really thick though. The Problem i am facing is that self collisions dont work for Thickness larger than point distance on the simulation geo. That leads to the knitted Fabric intersecting with itself later, and everything loosing Volume. Lower resolution has the problem that i cant control the mesh enough to make it fall as it should.

So.. what is the best approach here? I already tried some tetrahedal volumes, which could theoretically solve this problem, but result in a much less robust simulation in my case.

Or maybe some post simulation approach? Spacing the cloth away from itself after simulation? I coded something up in Vex but it didnt look very good.

Let me know if anyone has any Suggestions.

Thank you

Update: I have created some post processing Approach in Vex that uses ray intersection in normal direction paired with some smoothing to iteratively enforce the spacing. It works quite alright.
