Remarks

A light component which emits light from a single point equally in all directions.

Variables

  Type Name Description
Public variable uint32: 1 bUseInverseSquaredFalloff Whether to use physically based inverse squared distance falloff, where AttenuationRadius is only clamping the light's contribution.
Public variable float LightFalloffExponent Controls the radial falloff of the light when UseInverseSquaredFalloff is disabled.
Public variable float SoftSourceRadius Soft radius of light source shape.
Public variable float SourceLength Length of light source shape.
Public variable float SourceRadius Radius of light source shape.
