Subject line says it. ive used mod repository and a few others, im looking for a tutorial or something along those lines to help me work on making more realistic lighting in world at war. my map is a more gloomy and horror based one, i want to work with light rays a lot and maybe add some sort of lampposts. but my lighting skills are shit to say the least.

You could check some of the prefabs provided with the mod tools. For example "see1_light_exp.map" in _prefabs folder.
