There seems to have become a problem with the skin not sticking to the bones. When i stretch the leg out even if the foot has been weighted the skin seemes to fall off. i keep trying to tweak but something else just keeps going wrong with it.
it seems ok when i move the whole of the rigg, so i dont understand why it sticks then doesnt stick, its just werid.
i have some images of my vertex weighting and the problem, so hopefully that may help. Oh yes i am using Max 6 for this. Thanks alot for the help!
