I have been searching for days and have not been able to find an answer to this question.
I have a simple model. A thin cube with default collision physics applied and a plain 1x1 with default cloth physics applied. I checked self collision, leaving this default too.
I get the below result only a few frames in. It is like the mesh shrinks rapidly. I have relaxed the stiffness. lowered the weight. Also rendered with out self collision fine....I can not seem to work out why this is happening.
I have a sub divide on the plain with 6 steps...! lowering decrease render time but doesn't help the shrinking.
