Terrains SDOE also offers a wide variety of excellent user created or modified terrains. Due to the size of terrain files it is often difficult to find permanent and consistent online storage for them. As a result the files move around a lot and not all of the created terrains are always available for download. I will do my best to keep this page updated with the latest working links, but please be advised that if a link is dead it just may mean that file has changed location or is temporarily unavailable.
