How should I export finished models with textures in Maya? I'm guessing I should just export it as a .obj but will the texture be included or should I include the texture file with the model?
when you export in .obj you'll find the textures you used on it in the same directory where you exported it, after you'll just have to add them to the texture directory in Mount&Blade & create materials then apply them to the mesh after you import it in BRF editor.
ps:always make sure that the texture is loaded before the material & the material before the mesh.
