Welcome !
This forum has been set up to provide a discussion arena for the worlds for the Outerra visualization application. If you need to know more about outerra then visit the main site of
www.outerra.com.
Your in the Middle Earth world where a group called the Middle Earth Digital Elevation Model Project is freely distributing the terrain data for Outerra's free demo application - Anteworld. Their aim is to model the terrain of M.E. in great detail and have some of the notable landmarks within the world as 3D models.
The Anteworld visualization demo and compatible M.E. terrain data for it can be downloaded from the main Outerra web site
here.
At present we have just released the first version of the terrain data and don't have any 3D models for it. We hope that will change and people can generate some models for it.
