This isn’t just war... Its an all out apocalypse!
In the old days skies in levels were made out of simple environment maps. These days, we can actually render a camera inside a volume and use that as a sky portal, to make levels look like they go on for miles. Inside the volume we can render effects, aniamtion, models, anything we want really. This sky portal is supposed to be used for high rise building battles. The idea is that you map close buildings, and then let the sky portal take care of the effect in the distance, thus making the level look larger than it actually is. A nice trick.
