I made this image a while ago and I can't remember quite how I did it. What I can remember is that I used rendering clouds and adding noise, channels, and changing the color at some point. I did most of it from this video: http://www.youtube.com/watch?v=nODaUXV6CVE
But I didn't do everything from it, I tweaked something, it may have been the lighting rendering.
The reason I want to recreate this is because I need a version of it in higher quality. It's supposed to have a rock texture look to it, and I made it look golden.
This would be such a huge help if anyone can figure out how to replicate this. Thanks!
