I'm intrigued by this concept (and btw GothicX, that screenshot is droolworthy), but i've gotta say that i don't speak code, or chat manuscript for that matter. So, if someone could please explain in plain english (or direct me to a tutorial that does), i'd be grateful (sorry for hijacking, need help).

Does it reduce lag? Like if a large area is covered by fog?

Only if you combine it with a foghull.

Forsakahn, basically, you create a brush with a defined alphaMod, and cover the vertices of the brush you want to fade with it. The shaders of those brush surfaces have to have a vertex-defined value tho.
