            };

enum EDecayType

Search for all occurrences

Decay types.

Used for setting the attenuation of the light.

- eNone No decay. The light's intensity will not diminish with distance.
- eLinear Linear decay. The light's intensity will diminish linearly with the distance from the light.
- eQuadratic Quadratic decay. The light's intensity will diminish with the squared distance from the light. This is the most physically accurate decay rate.
- eCubic Cubic decay. The light's intensity will diminish with the cubed distance from the light.
