class Enlighten::UE4::UnrealDirectionalLightFunction

A light type similar to DirectionalLight which uses an approximation of a 2D light function to control the intensity of the lighting.

Name	Description
Enlighten::UE4::UnrealDirectionalLightFunction::CachedData	Cached data for DirectionalLight.

Name	Description
const Geo::u32 LevelCountMax = 16	Max Level count of Clipmap for light function.
Geo::v128 m_Direction	World space direction of light.
bool m_HasChanged	Whether the light has changed since it was last given to the extended direct lighting api.
Geo::v128 m_Intensity	RGB intensity of the light (linear space).
const Geo::u8 * m_LightFunctionClipmap	Clipmap for light function.
Geo::u32 m_LightFunctionClipmapLevelCount	Clipmap level count.
Geo::u32 m_LightFunctionClipmapResolution	Clipmap resolution.
Geo::u32 m_LightFunctionClipmapScale	Clipmap scale for light function.
const eLightType m_LightType	Type of input light corresponding to an eLightType enum value.
float m_MaximumDistance	The maximum distance from the camera at which systems are affected by this light.
Geo::u64 m_Padding	Unused (this class is usually extended by one that starts with multiple v128s)
Geo::v128 m_ViewPosition	Clipmap view position for light function.
VisibilityFormat::Type m_VisibilityType	Visibility type.

Name	Description
DistanceFilter(float)	Return true if this light affects a system at the specified distance from the viewer.
EvaluateLightFunctionClipmap(const Geo::v128 &, const Geo::v128 &, const Geo::v128 &, const Geo::u8 *, const Geo::v128, const Geo::u32, const Geo::u32, const Geo::u32)	Evaluate light function clipmap.
InputLightBase(eLightType)	Constructor.
InputLightBase(eLightType, bool)	Constructor.
