Question #642531 on Yade changed:
https://answers.launchpad.net/yade/+question/642531

Bruno Chareyre proposed the following answer:
Transparency and shades with openGL need specific models, not just turning transparency "on" (the models define e.g. how specular and ambient lights are transformed  when the rays from behind are crossing other surfaces before reaching the camera - just to give you an idea). Not extremely difficult to implement with some basic knowledge of openGL but nobody found it worth the effort yet, as it seems.
So it is not possible via the GUI now. I agree that paraview makes a nice (probably better) replacement.
