20 various materials, from grounds (x15) to hedges (x5), made via photogrammetry. Each material uses 4k Diffuse, Normal & Specular (when needed) maps ; 2k Heights map and 1k Occlusion map. All materials are instances of a Master material which allows you to easily activate/deactivate parallax or tesselation for all of the instances or one instance at a time. By default parallax is off and tesselation is on.
