its actually a lot easier than u would think. aside from some of the after effects, its all bryce. make sure u got a copy of it if ure gonna try this. for the latest 2 i did, i just had all the environmental settings off, just a completely black backdrop. i made the design i wanted, put the textures on i wanted, put the lighting in i needed. then i put it inside a giant sphere with a texture on it, usually the simple and fast textures produce the best results. zoom into the sphere, render and u got ureself that sort of picture
