I created a simple monkey mesh in Blender and exported the obj file to load on my C++ application. Upon inspection of the file I see lines like this:
vt 0.900583 0.804677 vt 0.899781 0.626257 vt 0.898822 0.786233 vt 0.887842 0.636527
Now, as far as I know vt denotes texture coordinates, right? If so, shoudn't these be zero since I'm not using a texture at all?
