How to make skin reacting to touch When you punch someone, skin will deform, same if you squeez your leg or other body part. I want this effect, because i'm making animation concentrated on interaction between characters.
I tried to do this with soft body, but it didn't work well, less or more it felt like a jelly. Is there any way to do this alone, in ordinary conditions and PC that isn't nuclear reator?
