The animations are designed to work from specific waypoints. They are prefixed with that compartment and waypoint. So "CR_CHIEF_Idle01" is set up to work on a character in waypoint CR_CHIEF. It doesn't have to be the Chief and is doesn't have to be used only in that waypoint. Things might not line up, you may get clipping, etc, if you use it somewhere else. The animations are in data\Characters\Animations.
