It is true I based my Osiris maps on NASA (?) data. Then I modified it trying to keep as much of the original data as possible (you wouldn't want mountains clumsily painted over with sand, would you?) and applied GIMP's Make Seamless filter. It simply made a chain of mountains covering where I painted over the seam. I then used it in a Celestia Addon and uploaded it from the textures/medres folder. If you're talking about the Aur map, I made it with a filter in Filter Forge (Photoshop) and modified it, changing colors and moving data. And if you're thinking that the POV-Ray TextureGen scene is a modified version of something copyrighted, you've got another think coming. I wrote that scene from SCRATCH and tested it, adding options and rendering it over and over. It is MINE, NOT someone else's scene. You need POV-Ray to use my texture generator. And worldbuilder is my screen name on another site.
