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:

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.
