I still have a question about the normal direction.
It's not that I'm completely stupid, but my english level don't help me sometimes to really undertand some technical thinks.

Let's say that an object looks right when I do the meshing, I mean I can clearly see the polygons, the backface curling work well ... however when I open
the .obj in my rendering software (actually modo), the normals are inverted. Is it something that happends sometimes and I have to deal with ? or it's also something
I can call a bug :) ... the problem actually is that I can't really flip the normals in modo because the vertex normal map is not inverted, so I still have something wrong.
I can only force to render everything in 'double side' mode, and that can be a problem later with some transparency surface.
