Hi! How can I attach a wrist to the hand so that there is not such a bad connection? This happens every time, when I pull out the bottom deformer - the more I stretch the deformer, the further wrist moves away.
Make your arm to have nice circle on the both ends like this guy’s.
Place the points of your deformers on the center of the circles. Notice that the circular “caps” of your arm does not get deformed right?
So you should place your hand on that part where does not get deformed. And boom! No more gaps between your arm and hand.
