How? It doesnt work for me, or at least not as expected, it gives me the same diamond shaped convex hull for instance on a ball or a head no matter if its switched on or off.

Is this they way it works?

How can you calculate collisions per vertex or plyogon with soft dynamics? Is this possible? I tried to include the shape in the soft dynamics sim, with all "hard" properties but it takes lot of computation time an gives unexpectet results.

I tried to use a low poly dummy object in place of a head but it didnt work very well, not usable.

So can you deform a cloth, or polygon hair along the exact surface of an object? Or do you need to use the cloth sim for that?

The bullet physics sim would be handy to use if its possible. I made some nice hair animation but it pokes through the head. or otherwise gets into the diamond shape of the collision hull - not usable-
