I am talking about one standardised map with a half/dozen differently lit / fogged etc rooms - with an indicated / enforced viewpoint of the room (eg teleport player to immobilised space)
There you proceed room by room to adjust your own settings to be able see what the prompts indicate you should be seeing for that particular room (in this room 1 you should adjust brightness/contrast until the ammo box disapears in the shadown but the zombie on the wall remains visible) etc...

If then mappers + players go through this setup we have a standardized setting that should be quite resilient to different engines and monitors.

It would also invalidate some engines that fuck too much with lighting etc.


It should at the very least be an interesting experiment no ? 

I'd be down for this if it was more involved as you describe but not sure you could do different fogs in the same map unless it was a mod like AD.
