Just thought of an enhancement we should consider.

• Enable night vision by allowing activate by the head. We need to figure out the way to enable night vision anyway if we ever allow night vision scopes (in that case) it could be tied to zoom being enabled.
• Enable night vision scopes

I think with the new RE might be able to piece together what filter the native scope widget uses and might be able to leverage that to turn on for the normal view.

something to look at
