In this amazing talk in the GDC Vault:

The developers used a tileable terrain to create a good sense of depth in the maps. They called that technique terrain skirts. In Battlefield:

They seem to use a similar technique, but instead of using tileable terrain, they constrain the gameplay area to a smaller part of the terrain, and then they use what appears to be low-poly versions of high-quality WorldMachine terrains in the horizon.

Do you guys have a similar technique? I have been exporting a low-poly OBJ from WorldMachine, including the normal map, diffuse and specular. I use that object as a decoration in the engine, but the result doesn't look very good. Maybe i should export a heightmap, import into MudBox, manually paint the textures, retopologize and then export?
