Here are a collection of ingame shots showing materials I developed during my time on the Avatar project. Initially being the only material artist on the team, these materials were created in conjunction with development of the terrain system and were designed to test different features of the system. I left part way through development so many of the materials you see here have had various refinements from the other material artists later in the project. Be sure to check out them out and the awesome work they did!
