relief south america max - South America, High resolution 3D relief maps by AridOcean

The set contains three models: a relief map of South America with surrounding area, a separate relief cutout of the land area, and a separate plain cutout
of the land outline.

The map projection is Lambert Azimuthal Equal-Area -60/-13. Geographic extents: W:-107; E:-30; S:-55; N:18.

The 3D relief is taken from reprojected NASA shuttle radar topography data, with the elevation exaggerated.
The relief is baked into a 561x750 mesh with 846891 polys, 424782 vertices (for the main map).

An additional 16-bit bump texture is used for fine-grained detail.

The texture is rendered from color processed NASA satellite images. Included are borders, cities, rivers and water areas.

Separate b/w texture masks are included for:

- land/ocean areas
- rivers and inland water areas
- cities
- borders
- ocean floor depth

A multi-layered material (3ds Max version only) together with the provided texture masks allows extensive changes to the appearance of the map.
Possible customizations include different colorings or complete removal of separate features like cities or borders.

A description of the multi-layered material and texture masks can be found in the accompanying PDF-manual.

Previews are rendered with mental ray, but the project uses only standard materials.

The .obj and .fbx versions will require new texture assignments after import.      
The .obj format is exported as triangles.

The compass rose is included as a bonus.
