Bump mapping and normal mapping does not work in loaded scene

Hello!
I loads a 3d model in .obj format. Some materials have a field "map_Bump" or "map_Kn" with texture for "bump mapping" or "normal mapping" accordingly. But the mapping does not work.

I have attached examples. It shows that the tread pattern of the wheel remains flat and has no relief.

In both examples, after importing the scene, the tire material has the type DiffuseMapMaterial. As I understand it, for the "bump mapping" in Qt3D there is no appropriate type of material, but for "normal mapping" it is and this is NormalDiffuseMapMaterial.
