Super rough physics test,
I've been wanting to do some paizuri/boobjob animations so I've been trying to figure out how to do it without the physics blowing up and going crazy with all the self-collisions and think it's starting to work out. Not completely perfect but I think it'll probably work out for animations, at least I hope it so.
Physics are scary to work with but they make everything look so much nicer when they work out.
