2-Sided Materials

Export 2 sided

Enable the export of two sided polygons. If a triangle has a two-sided material assigned to it in 3DS Max, then it is exported with the two-sided flag set in Renderware.

Preserve normals

When a two sided triangle is exported, the normals will only be correct for lighting one side. If this option is checked then the normals will be duplicated for each side of the triangle.
