Marigold, if you are using Bryce 4 open the Sky/Fog Lab (open the Sky/Fog Palette and click on the little cute cloud...) Then click on Sun and Moon to bring up those controls. In the lower right hand corner is a numerical control for setting the Azimuth and Altitude of the sun sphere in your shot. Azimuth is where on the horizon (angle) it is and Altidude is how high above the horizon (angle again). You can also use the track ball, but I use the numbers. Easier to control changes (to me at least). You can also control the size of the sun and the apparent size of the solar disk on the horizon on that screen too... Tom D
