I’m just imagining what soft-body physics could do in creating believable human characters. Some body parts (yes, breasts and buttocks come to mind) are soft and naturally deform, stretching and plumping depending on a person’s pose. We can use jiggle joints of course, but doesn’t fully achieve the effect.
The face is soft and could use soft body physics as well. To get facial animation looking good, we currently spend hundreds of hours making blend shapes and loading the face with a ton of joints. With soft-body physics, would it be possible for the face to deform naturally as the mouth moved? If so, that would be revolutionary.
