Nance, I tried the ShadowCam zoom change, with zero change in the shadow clipping. Another source of help said ECM (EMC?) conflicts could cause this. I was able to get a proper shadow by moving the LS closer to the model. Carolly, I was not too concerned about getting the science correct at this point. The shadow clipping was apparent with the LS where it was, so I rendered and posted. If I was finished with it, it would be in a gallery or delivered to the intended source. I may not even use that particular BG pic on the Cyc. thanks for the suggestions, -fritz
