Ahh, I did a proggie that renders Skysphere textures like that.
Damn handy because you can use it to give people 3D screenshots of your game, like instead of uploading a JPG you make a little viewer (just a camera stuck in the middle of a sphere and rotating with the mouse, user mistakingly trying to WASD move innevitable
). With decent res skybox images you could make a viewer too, except the quality would be much better with Skyboxes. It's a neat trick to render a terrain in DB then use it as the backdrop, gives awesome continuity and makes things much easier for the less artistic (bryce terrain exported to DBPro and rendered vs drawing terrain by hand = no contest)
