In the Map Library you can archive your own heightmap/texture sets. They can be consistently used as a template or saved as an intermediate result. If an item of the library should be updated, it just has to be saved with the same name after editing and will be replaced automatically. In the same easy way, an item can be deleted from the library at any time.
Example maps set available for download
Additionally there are also some example maps available for download (see link in the included instructions PDF), that can easily be uploaded into the library. You can use them to just give it a try and see how a heightmap with texture and shape is built.
