I believe they're working on fixing both Snarly's and D3D's scripts to work in Poser 12.

One of the problems is that they were forced to upgrade to Python 3, since Python 2 reached its end of life. That broke all the previous Python scripts.

Another problem is that the way some shaders work in Poser 12 has changed, and I think it's still being fiddled with.

What a lot of us are doing is keeping Poser 11 so we can run the old scripts, then rendering in Poser 12. Poser 12 is much faster at Superfly renders. Though you may have to adjust the materials a little.
