I've gotten that as well on highly angular body bits "colliding" with low-res mesh areas. And using the morphing brush is singularly unsatisfactory because it is a low-res mesh issue. I hadn't actually thought to add mesh for that reason, so thank you for that, Rosemaryr. I do increase mesh to allow for better sim folding and wrinkling, but I hadn't thought about that approach to resolve this particular problem.

This is a whole new concept, really: changing mesh to suit an image/sim need. And I don't want to necessarily increase the resolution of the entire mesh... just the problem areas. Completely different mindset to the conforming cloth workflow. For those of you using Blender, it would be nice if they developed some tools specific to this issue. BMesh might be an eventual answer, perhaps.
