Blender Wavefront obj Export problem

Hi everyone,

currently i try to use blender’s wavefront obj exporter with an
tutorial for obj import in c++

the importer basically loads 3 informations from the obj:

  • coordinates(v), texture coordinates(vt) and vertex normals(vn)

well, i got it working, using the original files, which were includet in the tutorial.
but if im trying to export my own model or even import the original one and export it again
it isnt visible in the c++ programm.

hereis the source file for the programm and 2 model files, which work
(sorry, the c++ project is for psp, and you need pspsdk in order to compile it)
