I'll play around with it in the next day or so to see if I can fine-tune it. The spots are inhibiting the light all-together altough I hanv't played with any of the values to try & fix it, should be able to get there from here. The image was a pain to get, I photographed the "real thing" from several sides & then composited them in Photoshop. Mapped it to a cylindrical spline object & placed it inside a cube of glass. I'm "outa here" for now...good luck.
