Hi Michael! Thanks for your file called BARTLE.ZIP which you uploaded to have us look at some artifacts in the shade of the RISER object. The problem was pretty easy to see, although confusing at first as to the cause. The problem goes away if you use Ray Tracing for LIGHT03, instead of Shadow maps. If you use shadow maps, the problem diminishes when you use a higher BIAS setting. However, I tried 8.0 and found that there was still evidence of those circular shadowy objects. There is a little about this in the 3DS Reference Manual – bottom of page 7-161. I hope this helps. Nik

Hi Nik, Thanks for getting back to me on that file with the shadow problem. I had tried changing the bias settings but not that high and didn't see any changes. As it turns out I did render with ray trace but never understood what actually produced the artifacts. Thanks again. Michael B.
