Understanding Light Transform propertiesLike cameras, lights can be animated in 3D space. Use the light Transform properties to change the angle and distance of the light source. Lights have all the Transform properties that a layer has, except for scale and anchor point. Also, like cameras, the directional lights, Spot and Parallel, have a point of interest. The light's point of interest, shown by the point of interest icon ( If the light is auto-oriented toward the point of interest, it continues to point at that point as you change its position. When you change the light's position by dragging the light icon in the Composition window, or by changing the light's position value in the Timeline window, the point of interest remains stationary within the composition and, as the light moves along the motion path, it continues to point at the point of interest. When you adjust the light's position by dragging its axes in the Composition window, the point of interest moves with the light, but the light continues to be oriented toward it. You could use this option to depict a light falling on a single subject as the light source moves past the subject. You could also use this option to follow a moving element. If the light is auto-oriented toward the motion path, then the light points only in the direction of the motion path. You could use this option to the depict a driver's perspective in viewing his own headlights while travelling down a dark road. If the light auto-orientation is turned off, then the light rotates freely along the motion path independent of the orientation of the motion path or the location of a point of interest. To move a light or point of interest in the Composition window:
