So, I created 2 procedural terrains in Vue. Everything you nooed to know is in the picture. Except the planets - I removed them later cause they sucked.
step 2 of 3
Bcs the planets sucked, I made my own in PS. I practically just followed this really good tut: http://gallery.artofgregmartin.com/tuts_arts/making_a_planet.html
step 3 of 3
Then I put the planet on a plane in 3ds Max (imported the vue scene, I have the xstream), and rendered it. Then I did some dodge/burn, brightness/contrast and color corrections in PS (really minor corrections, but add to the feel). =)
