The Environment Light uses a user-specified image, often an high dynamic range one (HDRI), projected on an infinitely large sphere to light the scene.

Only one Environment Light may be rendered at a given time. An Environment Light and a Sky Light cannot be rendered together. |
Creating an Environment Light
An environment light can be created in the GafferThree's Object table by right-clicking in the light list section and selecting Add → Environment Light, or by pressing the E key. Since they tend to interfere with object selection, environment lights are not shown in the Viewer.

ControllingPositioning an Environment Light
The
objectObject tab serves to specify if the environment light is Visible to Camera (resulting in filling the rendered image background with the environment) and the light's Transform (only the rotation will have a visible effect in a rendered image).
Controlling an Environment Light
The Material tab serves to control several light parameters. The effect of these are explained and illustrated in the next sections.
