Reads or writes the factors of attenuation applied to the light. Attenuation mimics how the intensity of light diminishes as you increase distance from the light.

Attenuation is determined using the following equation:

Elements

Name	Description
Constant Attenuation	Indicates the constant factor of attenuation (kc) you apply to the light. The constant factor of attenuation does not change as distance from the light increases.
Linear Attenuation	Indicates the linear factor of attenuation (kl) you apply to the light. The linear factor of attenuation drops in a linear manner as distance from the light increases.
Quadratic Attenuation	Indicates the quadratic factor of attenuation (kq) you apply to the light. The quadratic factor of attenuation drops by the square of the distance from the light.
