So before Advanced Fog of War, I would have my players either have Darkvision or a lightsource. If someone with a torch walked to close to someone with darkvision, their eyes adjusted to the light, no more darkvision (Realistically makes sense too, but its kind of a hassle to keep changing) With Advanced Fog of War though, there's now a View Distance, but I am not entirely sure how that works. I think it means I can set the light to 40, and dim to 20 so that it shines bright light out 20 ft and dim out 40ft, and then down in the View Distance, set it to 60ft and then the player will thus see 60ft out, while having bright and dim light, etc. If that is not how it is supposed to work, can someone please explain it to me? I've tried and cannot get it to work properly (or at least what I believe to be proper, could be working fine and I just dont realize.)
