Please help with the motion controller setup

Not sure what you mean by this but the controller simulates being at the end of your arm - you don’t 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 :wink:

For the trigger I use “MotionController (R) Trigger” for the trigger which works fine. Perhaps try it without the mapping first to make sure it’s not a problem with that?
