I’m trying to animate a character with an object which is sometimes in one hand, sometimes in the other, and sometimes in neither. I gave the object a bone, and made the hands track it with IK, which works fine. The problem is that sometimes I would much rather have the object’s bone track to a hand than vice versa, but I can’t figure out how to make this happen. I gave the object’s bone an IK constraint to track to the hand, but it won’t move – it only rotates. Is there any way to free this bone so that its head will move as necessary to satisfy the constraint?
