Constructor & Destructor Documentation

◆ FSortedLightSceneInfo() [1/2]

FSortedLightSceneInfo::FSortedLightSceneInfo ( const FLightSceneInfo * InLightSceneInfo )

inlineexplicit

Initialization constructor.

◆ FSortedLightSceneInfo() [2/2]

FSortedLightSceneInfo::FSortedLightSceneInfo ( int32 InSimpleLightIndex )

inlineexplicit

Member Data Documentation

◆ bClusteredDeferredNotSupported

uint32 FSortedLightSceneInfo::bClusteredDeferredNotSupported

True if the light doesn't support clustered deferred, logic is inverted so that lights that DO support clustered deferred will sort first in list Super-set of lights supporting tiled, so the tiled lights will end up in the first part of this range.

◆ bHandledByMegaLights

uint32 FSortedLightSceneInfo::bHandledByMegaLights

Whether the light should be handled by Mega Lights, these will be sorted to the end so they can be skipped

◆ bIESProfile

uint32 FSortedLightSceneInfo::bIESProfile

Whether the light uses IES Profile

◆ bIsCompatibleWithLightFunctionAtlas

bool FSortedLightSceneInfo::bIsCompatibleWithLightFunctionAtlas

◆ bIsNotSimpleLight

uint32 FSortedLightSceneInfo::bIsNotSimpleLight

Whether the light is NOT a simple light - they always support tiled/clustered but may want to be selected separately.

◆ bLightFunction

uint32 FSortedLightSceneInfo::bLightFunction

Whether the light uses a light function.

◆ bShadowed

uint32 FSortedLightSceneInfo::bShadowed

Whether the light casts shadows.

◆ bUsesLightingChannels

uint32 FSortedLightSceneInfo::bUsesLightingChannels

Whether the light uses lighting channels.

◆ [struct]

struct { ... } FSortedLightSceneInfo::Fields

◆ LightSceneId

uint32 FSortedLightSceneInfo::LightSceneId

Mega Lights must be sorted by GPU Scene Light Index - this field will only be set for MegaLights which don't rely on ordering of the other fields

◆ LightSceneInfo

const FLightSceneInfo* FSortedLightSceneInfo::LightSceneInfo

◆ LightType

uint32 FSortedLightSceneInfo::LightType

The type of light.

◆ Packed

uint32 FSortedLightSceneInfo::Packed

Sort key bits packed into an integer.

◆ SimpleLightIndex

int32 FSortedLightSceneInfo::SimpleLightIndex

◆ [union]

union { ... } FSortedLightSceneInfo::SortKey
