From the alien environments collection, its Sporata. Sure to make everyones top 10 list of most hostile environments, Sporata's beautiful green color hides its sinister nature. The only living organisms on Sporata are tiny green spores that cover everything. When any organic material or living creature enters Sporatas atmosphere it is instantly attacked by the spores. Quickly roots grow and the organism is consumed causing millions of new spores to bloom, fall away, and settle to the surface of the planet. I'm working on some pics with characters in them, but in the mean time, here's SPORATA. Its a pure Bryce render with Bryce terrains and textures. Photoshop used to add some green fog and my name.
