The bump maps on it looks outstanding though, especialy planets, I particularly like mars and the Intrepid in a picture on it.
See what i said? game engines are not able to use bump maps.
They use normal maps to fake the surface effects.
Both techs use maps to determine how the light should affect a surface in order to simulate relief effects.
Bump maps are a grayscale map (similar to speculars) where white stands to full height and black to deep inset, while average grey (125,125,125) stands for no surface change. Due to the way they are calculated, they are too slow to be used at game lighting calculation (real time)
Normal maps are RGB textures where the direction of the normal is stored at each pixel, so, the engine is able to simulate the lighting effects by simply using the normal variations, without any higher or lower effect. It's way faster, and in my opinion, also looks better even at renders.
As for normal maps at planets, i really don't think they should exist. Simply because you cannot notice that stuff from space. I've never seen a bump effect at a earth shot as example.
I'm looking forward for the atmosphere effects nano can add in the future more.
