In the plr file there is this line, "Moving Rearview="3" // Whether mirrors respond to head movement in cockpit (0=none, 1=position-only, 2=FOV-only, 3=both)" . If I set it 0, the mirrors reflect what is behind me but the FOV is very wide and is not adjustable. If I set it to 1, I can adjust left right up and down only and the reflection comes from the rear. If the setting is on 2 or 3, the reflection shows what's in front of the car and directional adjustments work but fov adjustment does not. I am using shift + seat adjust keys for mirror direction and shift + ctrl + seat keys for mirror FOV.
