Turn on the light.

This plugin available only for After Effects

Is there a light on in the room where you are reading this? Notice how it behaves in just this way. Object appear dimmer the further away they are from the lights illuminating them.

Falloff Lighting provides an enhanced lighting system to After Effects built-in light. Falloff Lighting is much more like that of the real world where light naturally decays or “falls off” as surfaces increase distance from the After Effects light.

Key Features
Falloff Lighting offers the control and flexibility you need to properly light your scene. You can display the distance from the camera to the corners of the layers. Also, you can adjust the distance scale to account for the scale of objects in your scene. You can also control the intensity of light highlighting an object and the gradual falloff as the distance from the light increases.

Why not just use AE? Falloff Lighting offers a key feature missing in After Effects. With After Effects’ built-in lights, it doesn’t matter how far away a layer is from a light, it is still illuminated the same amount by that light.
