Hiya Richardson, I hate to dissappoint but I'm as stumped by this as anybody. I've seen a few threads about this and the reason I haven't posted before is that I haven't been able think of anything useful to say. This time when I saw that refraction value of 1.9 I thought that had to be it, but I guess not. I think Stewer is the most likely person to come up with an answer for this one. He knows the render engine and the way the material nodes work better than anyone else I know. It might help if I could duplicate the effect on my own machine, but I haven't encountered it at all yet. Do you think you'd be able to set up a simple pzz file (say a sphere and a plane) that has this effect and then send it to me so I can try it out?
