Not sure what you mean by this but the controller simulates being at the end of your arm - you donât need to do anything special here. It should not rotate with the camera it only rotates when you move your arm. So if you keep your arm still and just move your head around the controller does not move
For the trigger I use âMotionController (R) Triggerâ for the trigger which works fine. Perhaps try it without the mapping first to make sure itâs not a problem with that?
