Syntax

static bool UpdateAlternateSkinWeights
(
    USkeletalMesh * SkeletalMeshDest,
    const FName & ProfileNameDest,
    USkeletalMesh * SkeletalMeshSrc,
    int32 LODIndexDest,
    int32 LODIndexSrc,

    bool ShouldImportTangents,
    bool bUseMikkTSpace,
    bool bComputeWeightedNormals
)

Remarks

This function apply the skinning weights from asource skeletal mesh to the destination skeletal mesh. The Destination will receive the weights has the alternate weights. We extract the imported skinning weight data from the SkeletalMeshSrc and we save the imported raw data into the destination mesh. Then we call UpdateAlternateSkinWeights without the SkeletalMeshSrc

Parameters

Parameter	Description
SkeletalMeshDest	The skeletal mesh that will receive the alternate skinning weights.
SkeletalMeshSrc	The skeletal mesh that contain the alternate skinning weights.
LODIndexDest	the destination LOD
LODIndexSrc	the Source LOD index
