Here's an example of how to aim lights in Bryce the easy way. Many people use the "grab and pull" method of aiming lights and camera. To me that method is imprecise and hard to control. Using the "Edit" menu is the best and most accurate way to move, rotate, scale and aim any light, object or camera in Bryce one axis at a time. You can even aim whole rows of lights as one (as shown in figure 4). I hope this helps eliminate your frustration and confusion. Good luck. ;-)
