Back on topic, if DAZ keep this thing free then maybe this could become a nice option for rendering Poser scenes as well ? lux is slow and octane is expensive and high end renderers don't have much support for poser... Could scripts be written to allow scene setup in Poser and rendering in DS/iRay ?

I don't believe DS will read a pz3 scene file, so you're probably left with doing an obj export and applying materials to that. That's not to rule out someone being able to read the DS sdk to work around getting the scene into DS. But then you still have to learn all the material settings which are different from the dials used for the regular gloss/spec model.
