Classes
| Name | Description |
|---|---|
| Enlighten::UE4::UE4InputLight::CachedData | Cached data for a UE4InputLight. |
Variables
| Name | Description |
|---|---|
| bool bSpotlight | True if the light should use spotlight falloff. |
| float CosOuterCone | Cosine of the outer cone half-angle. Used for spotlight falloff. |
| float CullAngle | Cone half-angle to use for culling the light, in radians. |
| Geo::v128 Direction | World space direction of the light. |
| const float * IESProfileTable | Pointer to lookup table for evaluating IES light profile. |
| Geo::v128 Intensity | RGB intensity of the light (linear space). |
| float InvCosConeDifference | cos(InnerConeAngle) - cos(OuterConeAngle). Used for spotlight falloff. |
| 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) |
| Geo::v128 Position | World space position of the light. |
| float Radius | Radius of the light. |
| float SourceLength | Length of light source shape (i.e. tube light). |
