Materials that are supposed to be shiny are diffuse and vice versa: Solution: For every "Ns" flip the value (newvalue = 1000.0 - value) or import with "Invert Specular Exponent" enabled, Explanation: The specification defines "Ns" to be the specular exponent, 0 is diffuse, 1000 is shiny (blender stops at 900).
