I'm not sure I follow. When I import the 3ds file I was hoping that the materials that I applied to the car from the original file would be attached to the car when I import it as a 3ds file? For instance, I apply a car paint material to the model in the max file, export it as 3ds then import the 3ds into another max file and voila the paint material is automatically attached. I'm not sure if I am making any sense here I just thought this could be done.
