View Full Version : pole vector problem

02 February 2007, 06:40 AM
Hi I have a problem with my wrist rig.

It usually works fine but now it has problem with one particular character.

I made an IK chain from shoulder to wrist. i orient constraint the hand control to the wrist bone. but when i move the pole vector, the hand (wrist bone) rotates around. technically it shouldnt rotate at all because it is orient contrained to the hand control. the only thing that should move is the elbow but I see it is influencing the rotation of the wrist as well even though the wrist is orient constrained to the control.

Any advice is much appreciated.
