Exports data to other systems, such as polygon-based animation systems.
Triangles – The file is triangulated according to the subdivision values specified in Render > Editors > Render Stats unless the Quality Type is set to GLOBAL in the Render Globals Quality Parameters window (Render > Globals) . Then the global parameters are used.
Quads – Useful if you need to output quadrilateral geometry with texture maps attached.
Outputs extra information, such as hierarchy, per-vertex normals, and texture sub-samples. This option is useful with the alias_to_wave and alias_to_sgo conversion programs, as well as custom-written ones.
The number of U and V texture samples per polygon.
