A cool cycles volume scatter node setup that I've been having fun with. I've also used it as a terrain when used on a plane. Render times arent too bad either if kept to direct lighting. I'm a serious noob, so dont judge too harshly :)
Editing my first post. Thank for the render I'll look into volume and scatter nodes to figure out how to come up with an outcome like this one day. If you ever get time and can remember some of what you did to make this please let us know.
