- Have you done something about UV on your metl_2 object that you haven't done on others ?
No, I proceded to same method for each of models !
- Do you have only one "material/texture" for each of your objects (dunno the correct terms for 3DS) ?
Yes, only one for each object in the model.
- If there's no way to make this working, have you tried the "alternative" solution, with DirectX files ? (see links about this a few posts above) ?
I didn't try, but let's try, maybe this will work
