To all who commented, thanks for the interest. To ockman, interesting test. In the past I have played around with the ambient material settings and that does make it possible to get some neat effects, but I would hope someone could still make this work like the lights do. That way you can have shadow effect and all the other cool effects of lighting, but just applied to that one object. Not familiar with P.C. Bos, but my hat is off to anyone who truly understand Poser lighting. :O)
