static void AppendSkinWeight ( const FMeshDescription& SourceMesh,
FMeshDescription& TargetMesh,
FSkeletalMeshAppendSettings& AppendSettings
)

   SkeletalMeshOperations.h  

static void ApplyRigToGeo ( FMeshDescription& RigMeshDescription,
FMeshDescription& GeoMeshDescription
)

 Applies the Rig / Skinning found in RigMeshDescription to the Geometry found in GeomeshDescription Desired behavior of this function was targeting FSkeletalMeshImportData::ApplyRigToGeo. SkeletalMeshOperations.h  

static void ConvertHardEdgesToSmoothMasks ( const FMeshDescription& InMeshDescription,
TArray< uint32 >& OutSmoothMasks
)

 A simpler variant of FStaticMeshOperations::ConvertHardEdgesToSmoothGroup that assumes that hard edges always form closed regions. SkeletalMeshOperations.h  

static bool CopySkinWeightAttributeFromMesh ( const FMeshDescription& InSourceMesh,
FMeshDescription& InTargetMesh,
const FName InSourceProfile,
const FName InTargetProfile,
const TMap< int32, int32 >* SourceBoneIndexToTargetBoneIndexMap
)

 Copies skin weight attribute from one mesh to another. SkeletalMeshOperations.h  

static void FixVertexInstanceStructure ( FMeshDescription& SourceMeshDescription,
FMeshDescription& TargetMeshDescription,
const TArray< uint32 >& SourceSmoothingMasks,
TArray< uint32 >& TargetFaceSmoothingMasks
)

 Helper function to follow behavior generated in FSkeletalMeshImportData::GetMeshDescription, just straight on FMeshDescriptions. SkeletalMeshOperations.h  

static bool GetPosedMesh ( const FMeshDescription& InSourceMesh,
FMeshDescription& OutTargetMesh,
TConstArrayView< FTransform > InComponentSpaceTransforms,

 Returns a mesh in the pose given by the component-space transforms passed in. SkeletalMeshOperations.h  

static bool GetPosedMesh ( const FMeshDescription& InSourceMesh,
FMeshDescription& OutTargetMesh,
const TMap< FName, FTransform >& InBoneSpaceTransforms,
const FName InSkinWeightProfile,
const TMap< FName, float >& InMorphTargetWeights
)

 Returns a mesh in the pose given by the bone-space transforms passed in. SkeletalMeshOperations.h  

static bool GetPosedMeshInPlace ( FMeshDescription& InOutTargetMesh,
TConstArrayView< FTransform > InComponentSpaceTransforms,
const FName InSkinWeightProfile,
const TMap< FName, float >& InMorphTargetWeights,
bool bInSkipRecomputeNormalsTangents,
bool bInWriteBonePose
)

 Returns a mesh in the pose given by the component-space transforms passed in. SkeletalMeshOperations.h  

static bool GetUnposedMesh ( const FMeshDescription& InPosedMesh,
const FMeshDescription& InRefMesh,
TArray< FTransform >& RefBoneTransforms,
FMeshDescription& OutUnposedMesh,
TConstArrayView< FTransform > InComponentSpaceTransforms,
const FName InSkinWeightProfile,
const TMap< FName, float >& InMorphTargetWeights
)

 Returns the unposed version of the provided posed mesh SkeletalMeshOperations.h  

static bool GetUnposedMeshInPlace ( FMeshDescription& InOutTargetMesh,
const FMeshDescription& InRefMesh,
TArray< FTransform >& RefBoneTransforms,
TConstArrayView< FTransform > InComponentSpaceTransforms,
const FName InSkinWeightProfile,
const TMap< FName, float >& InMorphTargetWeights,
bool bInWriteBonePose
)

 Returns the unposed version of the provided posed mesh SkeletalMeshOperations.h  

static bool RemapBoneIndicesOnSkinWeightAttribute ( FMeshDescription& InMesh,
TConstArrayView< int32 > InBoneIndexMapping
)

 Remaps the bone indices on all skin weight attributes from one index to another. SkeletalMeshOperations.h  

static void ValidateAndFixInfluences ( FMeshDescription& MeshDescription,
bool& bOutInfluenceCountLimitHit
)

 Function will do the following steps on the MeshDescription (SkeletalMeshDescription) : SkeletalMeshOperations.h  

static void ValidateFixComputeMeshDescriptionData ( FMeshDescription& MeshDescription,
const TArray< uint32 >& FaceSmoothingMasks,
int32 LODIndex,
const bool bComputeWeightedNormals,
const FString& SkeletalMeshPath
)

 Helper function to follow behavior generated in FSkeletalMeshImportData::GetMeshDescription, just straight on FMeshDescriptions It will do the following steps: SkeletalMeshOperations.h
