Let's say I have a map of a well lit manor, but I don't want the players to be able to see all the rooms at once. I have to create the walls of the manor with the Dynamic Lighting layer, and then create a light for each room. This will do the job but it'll also have some performance issues if there are just too many lights/rooms. With this suggestion, I could still create the walls of the manor, but instead of making individual lights, I could set a map-wide light setting so that the entire map could have the same lighting and vision could still be blocked.
