const eLightType m_LightType	Type of input light corresponding to an eLightType enum value.
float m_MinimumDistance	Distance from the camera changing the light to another(Refer to UnrealDirectionalLight).
Geo::u64 m_Padding	Unused (this class is usually extended by one that starts with multiple v128s)
VisibilityBuffer m_VisibilityBuffer	Visibility buffer.
