thanks. i can't really remember the light set up for this one I'm pretty sure that I did two passes. That's how I used to do things when I used 3DL (the default renderer). One pas with just uber environment, and another with a sunlight and then I would blend them in photoshop. I hated playing with multiple lights at once in DS and trying to get the settings right so it was easier to do it this way.
looking at the image it doesn't have signs of one of my three light setups, so the method I described is most likely. I often use 3 light setups but I just think this one happens not to be one.
