Variables

Protected

Name Type Remarks Include Path Unreal Specifiers
Bounds FBoxSphereBounds The bounds of the stored mesh, here so that users can quickly query this information without having to unpack the entire mesh. Engine/SkeletalMeshSourceModel.h  
CachedHasVertexColors TOptional< bool >   Engine/SkeletalMeshSourceModel.h  
CachedMorphTargetNames TArray< FName > List of all morph targets stored on the mesh. Engine/SkeletalMeshSourceModel.h  
CachedSkinWeightProfileNames TArray< FName > List of all alternate skin weight profiles stored on the mesh, NOTE: The default value is single-entry array with NAME_None to mark that this value has not been initialized yet / TOptional does not work with containers. Engine/SkeletalMeshSourceModel.h  
CachedVertexColorGuid FGuid   Engine/SkeletalMeshSourceModel.h  
MeshDescriptionBulkData TObjectPtr< USkeletalMeshDescriptionBulkData > Bulk data containing mesh description from imported or modeled geometry. Engine/SkeletalMeshSourceModel.h  
MeshDescriptionBulkDataMutex FCriticalSection Accessor mutex for the bulk data, since it can be accessed from any thread. Engine/SkeletalMeshSourceModel.h  
RawMeshBulkData TSharedPtr< FRawSkeletalMeshBulkData > The old mesh bulk data. Engine/SkeletalMeshSourceModel.h  
RawMeshBulkDataLODIndex int32   Engine/SkeletalMeshSourceModel.h  
TriangleCount int32 The number of triangles on the mesh, stored here so that users can quickly query this information without having to unpack the entire mesh. Engine/SkeletalMeshSourceModel.h  
VertexCount int32 The number of vertices on the mesh, stored here so that users can quickly query this information without having to unpack the entire mesh. Engine/SkeletalMeshSourceModel.h  

Functions

Public

Name Remarks Include Path Unreal Specifiers
Call this to clear all geometry from this source data. Engine/SkeletalMeshSourceModel.h  
Clears the currently stored mesh description objects, leaving the bulk data as-is. Engine/SkeletalMeshSourceModel.h  

bool CloneMeshDescription ( FMeshDescription& OutMeshDescription
) const

 Clones the current mesh description into the output object. Clones it from bulk storage if needed. Engine/SkeletalMeshSourceModel.h  

void CommitMeshDescription ( bool bInUseHashAsGuid
)

 Commits the currently cached mesh description (as retrieved via GetMeshDescription or TryGetMeshDescription) into bulk storage so that it will be persisted. Engine/SkeletalMeshSourceModel.h  
Create a new mesh description object on this container, obliterating whatever mesh might have been there before. Engine/SkeletalMeshSourceModel.h  

const FBoxSphereBounds & GetBoundsFast()

 Returns the bounds of the stored mesh description, without having to load it up from bulk storage. Engine/SkeletalMeshSourceModel.h  
Gets the cached mesh description, if there was one, otherwise tries to load it from the bulk data. Engine/SkeletalMeshSourceModel.h  

const FMeshDescriptionBulkData * GetMeshDescriptionBulkData()

 Return a read-only version of the bulk data. Engine/SkeletalMeshSourceModel.h  

TConstArrayView< FName > GetMorphTargetNames()

 Returns the list names of morph targets stored on the mesh, if any. Engine/SkeletalMeshSourceModel.h  

TConstArrayView< FName > GetSkinWeightProfileNames()

 Returns the list of names of alternate skin weight profiles stored on the mesh, if any. Engine/SkeletalMeshSourceModel.h  

int32 GetTriangleCountFast()

 Returns the number of triangles on the stored mesh description, without having to load it up from bulk storage. Engine/SkeletalMeshSourceModel.h  
Get the vertex color GUID as an optional value. Engine/SkeletalMeshSourceModel.h  

int32 GetVertexCountFast()

 Returns the number of vertices on the stored mesh description, without having to load it up from bulk storage. Engine/SkeletalMeshSourceModel.h  
Returns `true_ if there is mesh description data available on this bulk data object. Engine/SkeletalMeshSourceModel.h  

void Initialize ( USkeletalMesh* InOwner
)

 Initialize all sub-objects and other owned data that depends on knowing the skeletal mesh owner Engine/SkeletalMeshSourceModel.h  

Static

Name Remarks Include Path Unreal Specifiers

static void UpgradeMorphTargets ( FMeshDescription& InOutMeshDescription
)

 If necessary, convert morph targets from the old FVector3f[2] storage to the split representation where we store position per vertex, and normal per vertex instance Engine/SkeletalMeshSourceModel.h
