Basic Map and Light Improvements

[FlawlessHappiness]

Thanks for the good answers so far.

I'm (in my opinion at least) a bit more interested in the technical side on those things. Like: How to actually make it work in the game.

Because when i try to light a room, it often ends in either too small pointlights that shine through walls or too small ones that leave badly faded circles on floor/ceiling. When i try to use spotlights instead i end up with too narrow lighting that really looks unrealistic. Is there some trick to it?

I thought about a little darker pointlight around the original one to create some sort of "fade" effect.

I use spotlights as often as I can.
Shadows makes it more realistic IMO.
Spotlights are also able to fade, but anyway, always try to keep your colors low.
