human ik controller-effector moves despite being pinned
hi,
i created a skeleton and controls for it in the human ik.
then i pinned the rotation and translation of the Ctrl_LeftWirstEffector and the Ctrl_HipsEffector.
now when moving and rotaing the Ctrl_LeftShoulderEffector the Ctrl_LeftWirstEffector moves too a little.
why is this happening and how can i prevent a controller being moved by its parents?
