Yes, I figured it out mostly. Once the dimension is set (120cm) the coordinates are centimeter based. I added several lights and played with the MTL file.

d 0.3After I manually changed the glass color to almost white in sh3d.
result so far (light is at 3% and a ambient light behind me to light the metal)
(still not the matt glass I want on top and still missing the "light source/bulb")
The light also needs to become "smoother".
