Same here...

I tried a few of the supplied Poser 13 scenes.

They render fine in Firefly as well as CPU/Superfly, but are 100% black with GPU/Superfly.

Doesn't really bother me that much, as I'm sticking with Firefly for now, at least I until I have a proper GTR card.

And you can't expect a completely different render engine to work with a shader it doesn't understand, anyway.

(Although I noticed that some of my "optimized" Firefly skin shaders render nicely even with GPU/Superfly after some minimal modifications.)

Even the preview still looks "nice", too. (Unlike the "pure-breed" Superfly shaders that just show up white in OGL.)

So there might actually be a type of "hybrid" skin shader possible that works with both engines with none or just little modifications?
