I’ve been digging around to find out a good way of doing this, but couldn’t really find anything (or if I did, I didn’t understand it so don’t know if if was good).
Basically I have 3 bones in the arm: upper arm, forearm and hand. I have an object the hand has an IK solver constrained to, so when I move this object the arm moves as it should. If I rotate this object the hand moves as it should. What I am trying to do is add a bone that covers half the wrist, so I can parent half the forearm mesh to the forearm bone, and the other half to this bone. I have been trying to set it up so that when I rotate the object that rotates the hand, the wrist twist bone will rotate too, but only along it’s length.
I haven’t been able to manage this, as when I rotate the hand the bone ends up sticking out the side of the forearm. I have been tyring to keep it aligned with the forearm bone, but still rotate with the hand (to try and force it to rotate only along it’s length), but again no luck.
Does anyone have any suggeestions as to how to do this? Or a good method for doing this that works?
PS. Sorry to bring this up again (found a few posts about it with search) but I haven’t really found any good help on this.
