The material is the chipped rock with paths. As of the making of that image I had not gone through the manual far enough to find out how to edit materials so that is a default setting. I wanted to add more small items to it but it was 2 AM and my poor eye's hadn't blinked in about 9 hours of playing with vue and reading the manual. I am still working on it this morning though, got a little more real looking water version but I still don't like it..
