I'm working on a map set in the far north and I know from experience that snow can cause lightning storms. So, as wind rolls down from the mountains and brings snow. it also brings down a storm of plasma. Anyway, spiel over so any way or tutorial to make the sky light up periodically?

We're talking about the skybox texture itself flashing in sync with the environment lighting getting brigher, yes? There's one way I know of that any manipulation of the 2D skybox could be achieved: By using custom materials for your 3D skybox's walls (which must be a six-sided box with only 90 degree angles) that reflect custom cubemaps, as I touched on here, and then using the MaterialModify proxy to toggle between the two versions. It's an insanely complicated process and if you're insanely lucky it might even work.
