Illuminating different parts of the dungeon.

Hello, everyone. :) 1. Could you please tell me how to create different lighting in different parts of the dungeon? For example, if there is an Inferno Castle in the center, the lighting for it should be red, and in the left part, where there is a Necropolis, the lighting should be darker. 2. I would also like to know if it is possible to highlight small areas? For example, in the same dungeon, a 5x5 area is filled with crystals (not resources), and I would like to highlight them, creating, say, a separate light source.:rolleyes: I couldn't find anything similar on the forum. :) And one more question: I saw something about this somewhere, but I'll ask anyway, how do you create chasms in the dungeon?:confused:
