[Radiance-general] OBJ2MESH - Phong smooth shading and texture mapping

[Nicolas Roy]

This UV mapper tool is fantastic, I just made a test and both texture and
smooth shading was on. Thanks!

If your application (CAD) does not explicitly include vertex normal
info (vn) try this application:

http://www.uvmapper.com/

it gives you great flexibility in the .obj output and also does a
nice job at automatically unwrapping .obj's for a UV map that you can
then paint on, etc.

I use Lightwave for some modeling and it does not export vn's in
its .obj file exports.  I use UVMapper (Poser will also append vn's)
and then use obj2mesh and it works fine.  Remember also to subdivide
your mesh within your CAD program to a good level of detail to help
the smoothing along.
