Implementing a reflective object in Qt 3D C++

[Orad]

Hi,

I am trying to implement a front mirror object for a car in Qt 3D and my code is based on C++. (car.obj)

I have added such a mirror to the car object in the Blender and it works there,, however, when I load the car into the Qt, that specific surface that should act like a mirror is not working and just shows a solid coloured surface without any reflection capability. I don't know if this is a ray tracing issue by the Qt or there is other way to add a reflective material?

I am using QSceneLoader for texturing the car in Qt c++.

Thanks for the ideas in advance!
