The thing is when I apply this feature to the mesh it works fine, and the weights from the smooth skin it work fine too, but the problem comes when I creat the muscle and I want the muscle to influence the mesh maintaining the weights from the smooth skin, I can make it works but I'm force to apply default weights and I lose everything i've done. Anything I can do to maintain the original weights and at the same time make the muscle works?
Sorry for my bad english
