I'm working on some more procedural planets. I've got a rocky world done and a terran planet is currently rendering. The terran one is built like this:
[-]Main power fractal gives continent shape and vegetation color. (Perlin mix 1, I think.)
|__Then another power fractal for deserts. (Perlin billows)
|__Finally, a power fractal for mountain ranges. (Perlin ridges)
[-]Sphere at center of planet just slightly larger than planet for oceans:
|__Default water shader.
Default cumulus clouds with scale somewhere around 1e+006.
I'll attach them when they're ready.
Looking forward to seeing them! ;D
