These are the collision boxes I use. I add collision to a part of Kevin Punpikin's model and add cloth physics to these spheres. Then, in Celes' model, I use a modifier that interacts with this deformation, and in the end, it gives me the collision result between them.
It's a kind of crazy sequence of settings, but after some time doing it, I got used to it. But the biggest problem is the physics values, whenever I change the impact speed, I get all mixed up trying to adjust it. (-̩̩-̩̩͡_-̩̩-̩̩͡)
