Copy rotation rotates through wrong axis I want to rotate hand bone when I rotate IK bone as well. So I decided to using Copy Rotation constraint. Here's how looks like:



Nothing special, important thing is that Hand Bone has Copy Rotation to IK Bone. I set the Target Space and Onwer Space both Local Space.

But when I rotate IK bone, hand rotates totally wrong axis:




I think this happens because Copy rotation just copy the rotation values literally, my guess.

How do I make hand rotates properly? I think it needs to be change the rotation based on current rotation, but there's no option for that in Copy Rotation constraint.

Any advice will very appreciate it.
Copy hand bone. Make the copy a little larger or a little smaller than the original hand bone, so it'll be easy to select. Parent it only to the root bone and make it an IK target. That's the easiest way to avoid Copy Rotation problems and have clean, easy to work with rig.
