How to fix weight painting for a glove? I would like for the glove to stay put when I move the hand. I've been fighting with this for a while now trying all kinds of things with the weight paint. I have another version where I managed to do it (not perfectly, still moves a little) but I can't remember what I did. I tried copying the weights there but nothing. There's no actual hand under the glove by the way. I'm attaching the file.

Your troubles come from the fact that some gloves vertices weights are assigned to vertex groups unuseful (i.e. the thumb one): remove all assignements to unuseful vertex groups and assign some weight to the forearm bone only.
