FSmoothDynamicMeshVertexSkinWeights

Subclass of [TSmoothBoneWeights](API\Plugins\DynamicMesh\TSmoothBoneWeights) for dealing with smoothing of bone weights stored in the FDynamicMeshVertexSkinWeightsAttribute.

API > API/Plugins > API/Plugins/DynamicMesh

Subclass of TSmoothBoneWeights for dealing with smoothing of bone weights stored in the FDynamicMeshVertexSkinWeightsAttribute.

Example usage:

// Mesh whose bone weights we are smoothing FDynamicMesh SourceMesh = ... ;

// Setup the smoothing operator FSmoothDynamicMeshVertexSkinWeights SmoothBoneWeights(&SourceMesh, FSkeletalMeshAttributes::DefaultSkinWeightProfileName);

// Array of vertex IDs to apply smoothing to TArray VerticesToSmooth = ... ;

// Run the operator const float SmoothStrength = 0.2; if (SmoothBoneWeights.Validate() == EOperationValidationResult::Ok) { for (const int32 VertexID : VerticesToSmooth) { SmoothBoneWeights.SmoothWeightsAtVertex(VertexID, SmoothStrength); } }
