"Did you set up any lights in the scene?  Not the default Poser distant lights, something else like a point light or spot light."

I loaded a lightset that came with Luscious curves morphs for V4, nothing, then tried the default lights and nothing...I know Lux likes objects as lights sources, havnt tried that yet. Ill play with the tonemapping and load some point lights in as advised and see what pans out . I was thinking maybe i needed to use some of the other scripts first to export cameras lights etc seperatly..but I guess I just need to tinker more and try different styles of lights, thanks guys!
I cant wait to post my first test image!!
