FastTraxx just released an Earth .obp for Bryce. You can use that or study how it was made. If you don't wanna use that one just go here and dl the Earth and separate Cloud maps and place them on a sphere. Of course you'll have to adjust the layering yourself. The first link is FastTraxx's and the other are where the planetary maps are. http://www.chemicalstudios.com http://www.wam.umd.edu/~kamelkev/Ssystem/#Maps
