Creates a new control setup to follow a separate hierarchy from the rig control that drives the rotation of the rig control. Translation will remain controlled by the original parent.
This is used when you want to the control to continue to follow the position of it's parent but want the rotation to be handled by a separate hierarchy. Such as placing a head control into world space rotation so that the face remains facing the direction you set it instead of rotating with the body.
On creation the new control will bake the animation from the control it will drive after creating it's parent relationships so that you retain the world space animation that is currently on the rig.
On removal it will follow your Remove Component Settings 'Revert Animation' setting.
If un-checked the OverDriver control will bake it's animation back down to the rig control
If checked the OverDriver animation will be thrown out and the rig control will revert back to the animation curves that were present when the OverDriver was created.
