MTL materials are not being applied I have some free downloaded OBJ 3D objects like this cat (http://www.cadnav.com/plus/download.php?open=0&amp;aid=48009&amp;cid=3). It have its material MTL file to give the cat a real appearance. (http://img.cadnav.com/allimg/190709/cadnav-1ZF9121629.jpeg)
I have both files in same folder, of course. However, after I import the OBJ and press Alt + Z, it seems Blender ignores the texture. It happens with other OBJ/MLT imported. 

Please, could you help me? What am I doing wrong?
The problem is that the .mtl file is not assigning the texture. There is no map_Kd attribute saved.

If you append map_Kd cat.png as a new line, it will load the mesh with a texture. However the UV layout seems to be made with a mirror modifier applied which causes the texture to look very glitchy. This could be solved if you're willing to fix it.
