An other thing you may need to change is the material shine. Very polished material can't be set in Wings3d. Even you set Shiness to 1.0 the exporter will set the roughness parameter to 1.010000. In order to get a very polished material you need to change this value to something like roughness 0.010000 and the result you see in the image bellow - the light shine in the glass is smallest compared with the previous one that are looking like plastic:
