This is what I am talking about. here I took the cloth_plains I used to do the reflections, and turned down the transperancy to .2. I also added the spheremap background image. as you can see the lack of reflection of the side of the car creates the dark area you are talking about, now all I gotta do is work out how to use this on the photo LOL
