Nicolas,

You've received some pretty good information. If you are not 
concerned with texture coordinates, you could use a small tool 
of mine to generate surface normal vectors on a OBJ file. The 
program is called "rocksmooth" and it is in my "rocktools" 
package, available at:

http://mark.technolope.org/rocktools/

If you find that your modeller does not output texture or normal 
indexes, rocktools can read it and create just the normal vectors 
and indexes.

Good luck!
