struct Enlighten::UE4::UnrealDirectionalLightFunction::CachedData
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 Geo::u8 * m_LightFunctionClipmap | Clipmap for light function. |
| Geo::u32 m_LightFunctionClipmapLevelCount | Clipmap level count for light function. |
| Geo::u32 m_LightFunctionClipmapResolution | Clipmap resolution for light function. |
| 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 | Distance from the camera changing the light to another(Refer to Enlighten::DirectionalLight). |
| 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. |
| VisibilityBuffer m_VisibilityBuffer | Visibility buffer. |
