Here's a forum thread on how to move your eye position: https://forums.eagle.ru/showthread.php?t=164892
Pasting the relevant portion here:
RCTRL + RSHFT + KP4,2,6,8 = Moves your eyepoint L,D,R,U respectively
RCTRL + RSHFT + KP*, KPMinus = Moves your eyepoint fore and aft
RALT + KP0 = Saves your current eyepoint position
KP5 Recenters your view (Bind to a joystick or button box button with Joy2Key or other remapper to make centering simple)
[Note, you shouldn't have to bind anything to hit KP5, that's taken care of by the Recenter VR Headset in the UI Layer controls.]
