Creates a relationship between an attribute on one rig control to one of the translation channels on another rig control so that when the controlling rig control is translated in the scene, the translate value will drive the value of the attribute.
Primarily used for setting up blend shape attribute control onto animatable scene rig controls.
This is currently only creatable via script.
On creation all attribute animation is baked onto the rig control.
On removal all rig control animation is baked back into the attribute.
During setup a scalar value can be defined to convert the correct amount world space translation into reasonable attribute values.
