Light leaking through walls

[FlawlessHappiness]

Also a very good way to make realistic lighting is:
1: To have a source of lighting which is lighting up around it, but not the whole room.
2: Have darker point lights (in the same color, say lightsource = yellow. Dark pointlights = dark red or brown)... This makes it feel like the light is fading out.

In some custom stories, people just place a light-entity (like a candle) and then does nothing to it... It looks very unrealistic that the light is just stopping in a sphere around the candle..
