I got a problem with writing 3ds max. There is no place to specify normal vectors for the vertices of my triangles. So I only write out the triangles but the results are not good looking. You see strangly gouroud shaded triangles:
I think the problem is not in my data structures, as I can export different other formats (e.g. STL, VRML and POV) and it works perfect.
Do I maybe have an old format description of 3ds where no normal vectors could be defined?
Any other suggestions?
