So I've finally moved on to the lighting stage of my map, and I was wondering how to make the interior ceilings of my rooms lit. What I mean is, all my indoor lighting shines downward, and the roof is lost in total black. Also, my spotlights are too well defined; the map lighting looks like stage lighting. I've been using the lighting library I found on the site here. Any suggestions? Oh and also, I need a good roof texture for a building like the one in the center of Well. Recommendations, anyone?
