struct Enlighten::UE4::UnrealDirectionalLight::CachedData
  └>Enlighten::InputLightBase
Cached data for DirectionalLight.
Variables
| Name | Description |
|---|---|
| Geo::v128 m_Colour | RGB intensity of the light (linear space). |
| Geo::v128 m_Direction | World space position of light. |
| bool m_HasChanged | Whether the light has changed since it was last given to the extended direct lighting api. |
| Geo::u32 m_HasVisibility | Has visisibility data? |
| 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) |
| const Geo::u8 * m_VisibilityData | Visibility data. |
| Geo::s64 m_VisibilityDataU64 | Visibility data. |
