Lighting Effects

Didn't know where else to post this...perhaps we need a thread for techniques.

This stuff is mostly UnrealEngine3 specific, however, having looked at the article, I am almost positive these methods could all be reproduced with Unity. I am going to work on it today to see how the different sections can be moved to Unity; a lot of it is really cool stuff like particle fog, light beams, and things like accurate projected tree shadows and canopy/cloud shadowing, as well as some more advanced lighting techniques.
