Name Type Remarks Include Path Unreal Specifiers
bHardEdges bool Creates vertex instances per triangle to be able to have per-face vertex colors. Operations/TransferDynamicMeshAttributes.h  
BiasRatio float Ratio used to blend a vertex between its position and the center of the face (0 = vertex position, 1 = face centroid) Operations/TransferDynamicMeshAttributes.h  
bUseIntrinsicLaplacian bool If true, will use the intrinsic Delaunay mesh to construct sparse Cotangent Laplacian matrix. Operations/TransferDynamicMeshAttributes.h  
bUseParallel bool Enable/disable multi-threading. Operations/TransferDynamicMeshAttributes.h  
ForceInpaint TArray< float > Optional mask where if ForceInpaint[VertexID] != 0 we want to force the colors for the vertex to be computed Operations/TransferDynamicMeshAttributes.h  
LayeredMeshSupport bool If true, when the closest point doesn't pass the normal threshold test, will try again with a flipped normal. Operations/TransferDynamicMeshAttributes.h  
MatchedVertices TArray< bool > Outputs MatchedVertices[VertexID] is set to true for a target mesh vertex ID with a match found, false otherwise. Operations/TransferDynamicMeshAttributes.h  
NormalThreshold double Maximum angle (in radians) difference between target and source point normals to be considered a match. Operations/TransferDynamicMeshAttributes.h  
NumSmoothingIterations int32 The number of optional post-processing smoothing iterations applied to the vertices without the match. Operations/TransferDynamicMeshAttributes.h  
Progress FProgressCancel * Optional Inputs Set this to be able to cancel the running operation. Operations/TransferDynamicMeshAttributes.h  
SearchRadius double Optional Inputs for ETransferMethod::Inpaint method Radius for searching the closest point. Operations/TransferDynamicMeshAttributes.h  
SmoothingStrength float The strength of each post-processing smoothing iteration. Operations/TransferDynamicMeshAttributes.h  
TargetToWorld FTransformSRT3d Transform applied to the input target mesh or target point before transfer. Operations/TransferDynamicMeshAttributes.h
