Hi Morat, the .obj file that MoI exports has the specular color channel set to white (rgb of 1.0 1.0 1.0), so that if you turn on specular highlights it would show a white highlight. But it has the specular exponent set to 0 so that should mean specular highlights are off.

What do you see when you open it in Blender, are specular highlights on or off there?

The only things MoI sets regarding specular is the r g b triplet value and specular exponent value. Neither of these maps to a single value of 100% so maybe that's something that Blender decides to do by default.
