EShadowDepthRenderMode

enum EShadowDepthRenderMode

Enumerator
ShadowDepthRenderMode_Normal	The render mode used by regular shadows
ShadowDepthRenderMode_EmissiveOnly	The render mode used when injecting emissive-only objects into the RSM.
ShadowDepthRenderMode_GIBlockingVolumes	The render mode used when rendering volumes which block global illumination.

EShadowDepthType

enum class EShadowDepthType

Enumerator
None
VSM
Directional
Point
OnePassPoint

EShadowMeshSelection

enum class EShadowMeshSelection : uint8

strong

Used to select what meshes to draw into what shadow infos. Each mesh selects the support it has, and the shadow info stores a mask of what types it collects. This makes it easy to allow regular SMs to collect both types if VSMs are disabled.

DrawStencilingCone()

void DrawStencilingCone ( const FMatrix &  ConeToWorld, float  ConeAngle, float  SphereRadius, const FVector &  PreViewTranslation  )

extern

Renders a cone with a spherical cap, used for rendering spot lights in deferred passes.

GetOnePassPointShadowProjectionParameters()

void GetOnePassPointShadowProjectionParameters ( FRDGBuilder &  GraphBuilder, const FProjectedShadowInfo *  ShadowInfo, FOnePassPointShadowProjection &  OutParameters  )

extern

GetShadowMeshPassType()

OverrideWithDefaultMaterialForShadowDepth()

void OverrideWithDefaultMaterialForShadowDepth	(	const FMaterialRenderProxy *&	InOutMaterialRenderProxy,
		const FMaterial *&	InOutMaterialResource,
		ERHIFeatureLevel::Type	InFeatureLevel
	)

Overrides a material used for shadow depth rendering with the default material when appropriate. Overriding in this manner can reduce state switches and the number of shaders that have to be compiled. This logic needs to stay in sync with shadow depth shader ShouldCache logic.

SetupTranslucentSelfShadowUniformParameters()

void SetupTranslucentSelfShadowUniformParameters ( const FProjectedShadowInfo *  ShadowInfo, FTranslucentSelfShadowUniformParameters &  OutParameters  )

extern

Translucency shadow projection uniform buffer containing data needed for Fourier opacity maps.

UseCachedMeshDrawCommands()

bool UseCachedMeshDrawCommands ( EShadowDepthType  ShadowDepthType )

extern

GEmptyTranslucentSelfShadowUniformBuffer

TGlobalResource< FEmptyTranslucentSelfShadowUniformBuffer > GEmptyTranslucentSelfShadowUniformBuffer

extern

Global uniform buffer containing the default precomputed lighting data.
