The Sky Light is an environment light configured to use the 3Delight Sky shader, which can replicate various daylight lighting conditions.
Creating a Sky Light
A sky light can be created in the GafferThree's Object table by right-clicking in the light list section and selecting Add → Sky Light, or by pressing the A

key. Since they tend to interfere with object selection, sky lights are not shown in the Viewer.
