Pitklad, I find many shader effects such as face_off's RealSkinShader do seem to function in Poser 7 even using the Poser 4 render option, just not raytracing effects such as reflections... Often I render the scene in with the Poser 4 option and then the FireFly and composit them in Photoshop... FireFly has better shadows and can do AO but the Poser 4 render does have that crispness. I have used the Poser 7 P4 render with fancy P7 lights as well as shaders and still gotten good results.
