I imported a 3D model in obj format. It has 2 materials. One on front and other on back. Following are the files.
RectangleBackFaceColor.mtl (327 Bytes)
RectangleBackFaceColor.obj (514 Bytes)
When I export the same model in obj format only the front material is exported.
Also, in the material tab both the material can be seen.
How can I export both the materials?
