that would be great, although you may need to add a setting to decide how far down you need to go before the keypress begins.
this would only be detectable when in range of the camera though, so for standing VR you would need to wait for CV1’s 360 degree tracking for it to work at all times.
the most important thing is to make sure the viewpoint doesn’t go down as you move down, since that is merely a camera hack as far as the game is concerned.
