Cached data for a UE4InputLight.
Functions
Variables
| Name | Description |
|---|---|
| bool bFullSphere | Full sphere? |
| bool bLineLight | True if this light has line-based falloff instead of point. |
| Geo::v128 BoundsMax | Axis aligned bounding box. |
| Geo::v128 BoundsMin | Axis aligned bounding box. |
| bool bSpotlight | Is this a spotlight? |
| Geo::v128 CosOuterCone_InvCosConeDiff_CosCullAngle_NegSinCullAngle | Pack four floats into a single v128 to avoid bloat. |
| Geo::v128 Direction | World space direction of the light. |
| Geo::u32 HasVisibility | Has visibility? |
| const float * IESProfileTable | IES profile table. |
| Geo::v128 Intensity_SqrRadius | RGB intensity of the light, plus square-radius packed into the w component. |
| Geo::v128 LightPos | World space position of light. |
| 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) |
| RadialFalloffModelType::CachedData RadialFalloffModel | Cached data for radial falloff model. |
| const Geo::u8 * VisibilityData | Visibility data. |
| Geo::s64 VisibilityDataU64 | Visibility data. |
