This was a big project I tackled. I'm a huge tabletop miniatures enthusiast, and I felt there was a real lack of quality rocky terrain. All the rocks were sculpted by me in Zbrush, and printed on an FDM printer. All of the color photographs are of the real physical models I painted and detailed.
The old Kickstarter campaign is here:
