Excellent! Many many thanks, I'm currently beating my head off my desk trying to get anything resembling a cave. This is nice and simple and yet looks really good I'll go and give it a shot. The grey/height map is a nice guide as to how to get that nice flooring effect. Not sure if I'll use those aspect in this particular image but it's good all the same and one I'll bear in mind for the future. Thanks again. :o)
