This is a set of 8 Normal maps with Height maps included. The two together very quickly give good results for hilly, mountainous and other types of terrain. The Height maps displace the geometry while the normal maps give incredible detail without increasing the polygon count. The rendered thumbnails above were rendered with a low polygon count yet maintain good detail with the addition of the Normal maps in the bump channel. Some were rendered with only 7,200 polygons; a relatively low poly count for terrain generation. A detailed description of the process and one max file to demonstrate the process are included. The bluish, purple images are the Normal maps. Enjoy!
