Name	Description
Enlighten::UE4::UE4InputLight::CachedData	Cached data for a UE4InputLight.

Name	Description
bool bSpotlight	True if the light should use spotlight falloff.
float CosOuterCone	Cosine of the outer cone half-angle. Used for spotlight falloff.
float CullAngle	Cone half-angle to use for culling the light, in radians.
Geo::v128 Direction	World space direction of the light.
const float * IESProfileTable	Pointer to lookup table for evaluating IES light profile.
Geo::v128 Intensity	RGB intensity of the light (linear space).
float InvCosConeDifference	cos(InnerConeAngle) - cos(OuterConeAngle). Used for spotlight falloff.
bool m_HasChanged	Whether the light has changed since it was last given to the extended direct lighting api.
const eLightType m_LightType	Type of input light corresponding to an eLightType enum value.
Geo::u64 m_Padding	Unused (this class is usually extended by one that starts with multiple v128s)
