Functions

Public

Name Remarks Include Path Unreal Specifiers

bool DoMerge ( TArray< FRefPoseOverride >* RefPoseOverrides
)

 Merge/Composite skeleton and meshes together from the list of source meshes. SkeletalMeshMerge.h  

bool FinalizeMesh ()

 Creates the merged mesh from the 'SrcMeshList' (note, this should only be called after MergeSkeleton()). SkeletalMeshMerge.h  

void MergeSkeleton ( const TArray< FRefPoseOverride >* RefPoseOverrides
)

 Create the 'MergedMesh' reference skeleton from the skeletons in the 'SrcMeshList'. SkeletalMeshMerge.h  

Static

Name Remarks Include Path Unreal Specifiers

static void BuildReferenceSkeleton ( const TArray< USkeletalMesh* >& SourceMeshList,
FReferenceSkeleton& RefSkeleton,
const USkeleton* SkeletonAsset
)

 Builds a new 'RefSkeleton' from the reference skeletons in the 'SourceMeshList'. SkeletalMeshMerge.h  

static bool OverrideReferenceBonePose ( int32 SourceBoneIndex,
const FReferenceSkeleton& SourceSkeleton,
FReferenceSkeletonModifier& TargetSkeleton
)

 Override the 'TargetSkeleton' bone pose with the pose from from the 'SourceSkeleton'. SkeletalMeshMerge.h  

static void OverrideReferenceSkeletonPose ( const TArray< FRefPoseOverride >& PoseOverrides,
FReferenceSkeleton& TargetSkeleton,
const USkeleton* SkeletonAsset
)

 Overrides the 'TargetSkeleton' bone poses with the bone poses specified in the 'PoseOverrides' array. SkeletalMeshMerge.h
