Hmmm.. I know that when you run the script it sets the bump map value to like 0.000097 - I usually go in and set that back to 0.0002, but now that you mention it, I ran the script again right before the render and forgot to do that, so there's extremely minimal bump-mapping (combined with the minimal granite displacement mapping) in this image. On the lights... Poser crashed not long after this render, so I can't check it, but I think I ended up with the IBL light set to like 65% and the Point light set to about 50%.
