Tips for making atmospheric lightning areas

[hunchbackproduction]

Also, if you want to add a different overall feel to a map, a good way to do it is with lighting and changing it's colours.

You could place a boxlight covering the whole map and making it dark blue so it gives a night time effect., or in turn make the boxlight greenish/brownish to give a feeling of nostalgia or mystery.
A thing to remember is that a room with boxlight will not drain sanity.
