Thanks! Each group gets its own box on the sheet, with some margin around the skin. Anything you paint in that box belongs to the closest bone of that group in the rest pose. So a hat painted in the head's box rides on the head, and a sword next to the hand goes with the hand.
Thanks "feels like real engineering" is high praise! Each group gets its own box and anything painted in it belongs to the closest bone in the rest pose hat rides the head, sword goes with the hand. Quick q does closest bone hold up for big multi bone capes or would you want manual assignment there?
