Syntax

static TRefCountPtr< FShadowMap2D > AllocateInstancedShadowMap
(
    UObject * LightMapOuter,
    UInstancedStaticMeshComponent * Component,
    TArray< TMap< ULightComponent *, TUniquePtr< FShadowMapData2D >>> && InstancedShadowMapData,
    UMapBuildDataRegistry * Registry,
    FGuid MapBuildDataId,
    const FBoxSphereBounds & Bounds,
    ELightMapPaddingType PaddingType,
    EShadowMapFlags ShadowmapFlags
)

Remarks

Allocates texture space for the shadow-map and stores the shadow-map's raw data for deferred encoding. If the shadow-map has no shadows in it, it will return NULL.

Parameters

Parameter	Description
Component	The component that owns this shadowmap
InstancedShadowMapData	The raw shadow-map data to fill the texture with.
Bounds	The bounds of the primitive the shadow-map will be rendered on. Used as a hint to pack shadow-maps on nearby primitives in the same texture.
InPaddingType	the method for padding the shadowmap.
ShadowmapFlags	flags that determine how the shadowmap is stored (e.g. streamed or not)
