A lot of times the DUF files load fine for me in Carrara8.5, I don't have this set though so can't test it, but maybe will pick it up to give it a try...

In the meantime I just loaded up Stonemason's Contemporary Living scene which I added as a .duf Studio file to my 'My Daz Library' folder, just to test the theory. It loaded into Carrara fine, and I did a quick Octane render of the scene 'as is' without changing a single texture except to make the ceiling lights octane emitters. Seemed to work great for me, not sure why the Chinatown scene would be any different, but now that I'm curious I might have to pick it up and give it a try.

Sidenote: Duf textures and the texture translations of Studio textures into Carrara seem pretty good, right off the bat. I loathe Studio and up til now have loaded everything into Carrara usually from Poser, but the textures always require lots of changing. I think I could get away with duf version textures without much change.

...of course, being a Carrarist, I would still have to tinker with textures as that's now part of my nature :) But it is interesting to see that Studio textures apparently translate much better than Poser textures.
