Unity3D doesn't support volume textures. This makes procedural texturing of models using object or world space (instead of UV coords) very hard.
After much banging of head on keyboard, I think I've succeeded in using a 2D noise texture to fake 3D noise, and create a reasonable looking planet texture. Next step, atmosphere.

Are you willing to share or sell your procedural texturing shader (because I believe that's what you do - create texture on GPU, right?)?
Because I've managed to create procedural textures in realtime on CPU, with help of libnoise, but I'm a complete moron when it comes to shaders ;)
If you are willing to contact me about this matter, please, give me a shout on kaldrick@gmail.com
