Variables

Type	Name	Description
TStrongObjectPtr< UUsdAssetCache2 >	AssetCache	Where the translated assets will be stored
bool	bAllowInterpretingLODs	If true, prims with a "LOD" variant set, and "LOD0", "LOD1", etc.
bool	bAllowParsingGroomAssets	If true, means we will try generating GroomAssets, GroomCaches and GroomBindings
bool	bAllowParsingSkeletalAnimations	If true, we will also try creating UAnimSequence skeletal animation assets when parsing Skeleton prims
bool	bAllowParsingSparseVolumeTextures	If true, means we will try generating Sparse Volume Textures
TSharedPtr< UE::FUsdGeomBBoxCache >	BBoxCache	Bounding box cache used for the USD stage in case we have to spawn bounds components
bool	bCollapseTopLevelPointInstancers	If true, will cause us to collapse any point instancer prim into a single static mesh and static mesh component.
bool	bIsBuildingInfoCache	True if we're building the InfoCache assigned to this context.
bool	bIsImporting	True if we're a context created by the USDStageImporter to fully import to persistent assets and actors
UsdUtils::FBlendShapeMap *	BlendShapesByPath	Where we place imported blend shapes, if available
bool	bMergeIdenticalMaterialSlots	If enabled, when multiple mesh prims are collapsed into a single static mesh, identical material slots are merged into one slot.
bool	bReuseIdenticalAssets	If true, whenever two prims would have generated identical UAssets (like identical StaticMeshes or materials) then only one instance of that asset is generated, and the asset is shared by the components generated for both prims.
bool	bSequencerIsAnimating	True if the Sequencer is currently opened and animating the stage level sequence.
bool	bTranslateOnlyUsedMaterials	Skip the import of materials that aren't being used by any prim on the stage
TArray< FHairGroupsInterpolation >	GroomInterpolationSettings	Groom group interpolation settings
TSharedPtr< FUsdInfoCache >	InfoCache	Caches various information about prims that are expensive to query
EUsdDefaultKind	KindsToCollapse	Whether to try to combine individual assets and components of the same type on a kind-per-kind basis, like multiple Mesh prims into a single Static Mesh
ULevel *	Level	Level to spawn actors in
FName	MaterialPurpose	The material purpose to use when translating material bindings
TMap< FString, TMap< FString, int32 > > *	MaterialToPrimvarToUVIndex	When parsing materials, we keep track of which primvar we mapped to which UV channel.
FUsdMetadataImportOptions	MetadataOptions
int32	NaniteTriangleThreshold	If a generated UStaticMesh has at least this many triangles we will attempt to enable Nanite
EObjectFlags	ObjectFlags	Flags used when creating UObjects
USceneComponent *	ParentComponent	The parent component when translating children
EUsdPurpose	PurposesToLoad	We're only allowed to load prims with purposes that match these flags
FName	RenderContext	The render context to use when translating materials
EUsdRootMotionHandling	RootMotionHandling	Describes what to add to the root bone animation within generated AnimSequences, if anything
UE::FUsdStage	Stage	Pxr::UsdStage we're translating from
int32	SubdivisionLevel	Subdivision level to use for all subdivision meshes on the opened stage. 0 means "don't subdivide"
TMap< UTexture , TSet< UMaterialInterface > >	TextureToUserMaterials	Sometimes we must upgrade a material from non-VT to VT, and so upgrade all of its textures to VT (and then upgrade all materials that use them to VT, etc.).
float	Time	The time at which we are translating
TArray< TSharedPtr< FUsdSchemaTranslatorTaskChain > >	TranslatorTasks

Constructors

	PRAGMA_DISABLE_DEPRECATION_WARNINGS	FUsdSchemaTranslationContext ( const FUsdSchemaTranslationContext& Other )	Explicitly declare these defaulted special functions or else the compiler will do it elsewhere and emit deprecated warnings due to usage of bCollapseTopLevelPointInstancers
	PRAGMA_ENABLE_DEPRECATION_WARNINGS	FUsdSchemaTranslationContext ( const UE::FUsdStage& InStage, UUsdAssetCache2& InAssetCache )
