Oh what great fun I had with weight painting, ahem. I can honestly say I do not enjoy weight painting. It took me two afternoons to do it. I kept accidentally painting vertex’s on the opposite foot and when the model would move I would get this giant spike protruding from say her ankle. I think that in order to enable successful weight painting i need to consider it while i am making the mesh and putting in the skeleton. for example her arms, i could have either made the mass under her arms smaller or put the shoulder joint further out to stop the geometry disappearing into each other. There was no major problems with deformations in the mesh, overall it bends quite well, I’d say the worst is the back of the knee but its not that bad.
