hi all,
i have a rigging problem.
i have the basic character skeleton setup, and on the arm i have the hand bone constrained to a control box that controls the rotation and position of the hand. i am animating IK.
the problem i have is that when i animate the hand and the up vector, sometimes the whole wrist twists like 2000 degrees and screwsup the geo. it also happens when i scrub my animation too fast back and forth. also when i move the upvector a little extreme then if i press ctrl z it does the same thing.
if i go to the kinematics of the hand bone, and i wiggle the values or if i reset the transformation value it jumps back to normal. there are no keys on the bones.
the rotation value of the control box is normal when the hand bone's ( which is orientation constrained to the control box ) value is totally random.
i already asked some advanced XSI users and they didnt seem to know. Please any help would be appreciated ! I use XSI 5.11
