I tend to use a lot of legacy content. I used to use Reality as it gives such great results but decided I should embrace SuperFly. However, I find my use of legacy content in Poser 11 needs Snarly’s EZ-Skin. And now it seems Poser 12 breaks SuperFly shaders resulting in EZ-Skin not working as it used to. So I can’t see me upgrading until Bondware fix the shader issues, which are frankly not acceptable. Creating a scene in Poser 11, opening that scene in Poser 12, it has to render pretty much the same or Poser 12 is dead in the water imho.
