Functions

  Type Name Description
Public function void

Clear ()

  
Public function Const bool Returns whether we contain any info about prim at 'Path' at all.
Public function Const bool

ECollapsingType CollapsingType
)

  
Public function Const TMap< UE::FSdfPath, TArray< TWeakObjectPtr< UObject > > >

GetAssetsForPrim ( const UE::FSdfPath& Path
)

  
Public function Const 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
Public function Const TSet< UE::FSdfPath > Returns a list of all prims we have generic info about.
Public function Const 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'.
Public function Const TSet< UE::FSdfPath >

GetMaterialUsers ( const UE::FSdfPath& Path
)

 Returns the set of paths to all prims that have a material:binding relationship to the particular material at 'Path', if any.
Public function Const TArray< UE::FSdfPath >  
Public function Const T *  
Public function TOptional< uint64 >  
Public function TOptional< TArray< UsdUtils::FUsdPrimMaterialSlot > >  
Public function TOptional< uint64 > Provides the total vertex or material slots counts for each prim and its subtree.

IsMaterialUsed ( const UE::FSdfPath& Path
)

  
Public function Const bool

IsPathCollapsed ( const UE::FSdfPath& Path,
ECollapsingType CollapsingType
)

  
Public function Const bool Returns true if Path could potentially be collapsed as a Geometry Cache asset.

Public function Const UE::FSdfPath

UnwindToNonCollapsedPath ( const UE::FSdfPath& Path,
ECollapsingType CollapsingType
