Other post processing effects help add to that variety. You get visual tricks like lens flare and bloom from spotlights, all rendered in post. Equally impressive is the manner in which shadows shift across the world, based on a planet's rotation and position to a sun, creating a proper night-day cycle. Sadly, nearby moons stay in a fixed position regardless of this cycle - a bit of a cheat bearing in mind the mathematical precision and correctness found in the game. But it's a rare example of a title simulating planetary bodies for its lighting, while roaming on the ground.
