Positioning a Distant Light
The distant light's transform can be edited in the Object tab. While positioning and scaling an infinitely far object makes little sense, adjusting the translation and scale can make manipulating a distant light in the Viewer easier. During rendering, only the rotation has an effect.
Adjusting a Distant Light Shape Visibility
A distant light can be made Visible to Camera in the Object tab. It will be represented as a disk in the image background.
Controlling the Light from a Distant Light
The Object tab allows specifying the Angular Diameter of the distant light (as is explained in more details below). The Material tab serves to control several light parameters. The effect of these are explained and illustrated in the next sections.
