Six planetary resolution tileable terrain heightmaps, provided as TIF and also incorporated in 12 example scenes which include materials specifically matched to the geometry of those maps.

Each example scene is also accompanied by a short video tutorial by either Horo or myself (depending on the author of the scene) drawing attention to various aspects of that scene.

Two 800 pixel diameter specular convolved HDR images (as used in his six examples) are also provided by Horo.
