TSet< UE::FSdfPath >	GetAuxiliaryPrims ( const UE::FSdfPath& MainPrimPath )	The inverse of the function above: Provide it with the path to a Material prim and it will return the set of paths to all Shader prims that need to be read to translate that Material prim into material assets
TArray< UE::FSdfPath >	GetChildren ( const UE::FSdfPath& ParentPath )	Retrieves the children of a prim from the cached information.
TSet< UE::FSdfPath >	GetKnownPrims ()	Returns a list of all prims we have generic info about
TSet< UE::FSdfPath >	GetMainPrims ( const UE::FSdfPath& AuxPrimPath )	Returns the paths to prims that, when translated into assets or components, also require reading the prim at 'Path'.

TOptional< TArray< UsdUtils::FUsdPrimMaterialSlot > >	GetSubtreeMaterialSlots ( const UE::FSdfPath& Path )
TOptional< uint64 >	GetSubtreeVertexCount ( const UE::FSdfPath& Path )	Provides the total vertex or material slots counts for each prim and its subtree.
bool	IsEmpty ()
bool	IsMaterialUsed ( const UE::FSdfPath& Path )
bool	IsPathCollapsed ( const UE::FSdfPath& Path, ECollapsingType CollapsingType )
bool	IsPotentialGeometryCacheRoot ( const UE::FSdfPath& Path )	Returns true if Path could potentially be collapsed as a Geometry Cache asset
bool	IsPrototypeTranslated ( const UE::FSdfPath& PrototypePath )
void	LinkAssetToPrim ( const UE::FSdfPath& Path, UObject* Asset )
void	MarkPrototypeAsTranslated ( const UE::FSdfPath& PrototypePath )

void	RemoveAllAssetPrimLinks ()
TArray< UE::FSdfPath >	RemoveAllAssetPrimLinks ( const UObject* Asset )
void	ResetTranslatedPrototypes ()	Marks/checks if the provided path to a prototype prim is already being translated.
bool	Serialize ( FArchive& Ar )
void	UnlinkAssetFromPrim ( const UE::FSdfPath& Path, UObject* Asset )
UE::FSdfPath	UnwindToNonCollapsedPath ( const UE::FSdfPath& Path, ECollapsingType CollapsingType )	Returns Path in case it represents an uncollapsed prim, or returns the path to the prim that collapsed it.
