[Paraview] Diffusivity and Specular Properties

[Jon Wong]

I'm interested in using paraview as a replacement for tecplot. I can 
reproduce almost everything except that tecplot seems to be using 
different diffusivity/specular properties as their material is slightly 
shinier and more reflective than the default paraview material. Is there 
any way to access these properties via python or through the Object 
Inspector>Display>Style>Material settings?

I'm using Paraview 3.10.0 on linux 64-bit for reference.

Thanks
