As Laszlo said, Mesh intentionally doesn't load in the material 
properties from an mtl file. This is so that you can specify your own 
Material. This is more flexible than the lighting models offered by mtl 
files (traditional Phong model).

The SceneLoader generates a Mesh and a Material component by using 
assimp to get hold of the properties.
