I hadn’t noticed that as of the end of September there’s now a DAZ to Blender Bridge 2.0, which now sends more than characters in A-poses (which was the state-of-play, last I heard). Still free, but still no manual installer.
Now in version 2.0 it apparently takes across whole scenes, and can also convert all the way back to the original Genesis figures. No longer works in Blender 2.79, apparently.
However, for artists rather than content developers, the only reason I can see that you’d want to take a full posed scene across is to run it in real-time in Blender’s Eevee or try to do some NPR. In mean, when you have native iRay rendering in DAZ Studio, why would you go to all the hassle of porting the scene over to Blender’s Cycles with the likelihood of broken or ‘off’ textures and suchlike?
