These two heavily-weathered and mishappen sidewalk materials were photoscanned and processed to have a very high level of texture detail, including 9K albedo maps, 9k normal maps, and 9k/16-bit displacement maps for displacing the mesh without appearing blocky. The Blender file is set up so that the sidewalks are extremely low-poly, and the simple-subsurf modifiers allow the customer to control the level of detail in the sidewalk meshes. The sidewalks are tileable and can be arrayed along a curve if the user so desires. The Simple Grass particles are included with the Blender file.
