Adds a volume light to your scene.
A major advantage of using a volume light is that you have a visual representation of the extent of the light (the space within which it is bound).
Tip
You can use a volume light as a negative light (to remove or decrease illumination) or to lighten up shadows.

The falloff of light in the volume can be represented by the color ramp (gradient) attribute in Maya, which prevents the need for various decay parameters, and also provides additional control. The color gradient is also useful for volume fog.
You can achieve different effects with light direction. Outward behaves like a point light and Downward acts like a directional light. Inward reverses the light direction for shading, giving the appearance of inward illumination. When using shadows with Inward light direction you may get unexpected results. In all cases the light shape dictates the extent of the light.
