Abstract
We propose a method to transfer skin weights and helper joints from a reference model to other targets. Our approach uses two types of spatial proximity to find the correspondence between the target vertex and reference mesh regions. The proposed method first generates a guide weight map to establish a relationship between the skin vertices and skeletal joints using a standard skinning technique. The correspondence between the reference and target skins is established using vertex-to-bone projection and bone-to-skin ray-casting using the guide weights. This method enables fully automated and smooth transfer of skin weight between human-like characters bound to helper joint rigs.

1.Load plugin
1.move built .mll to plugin directory [your Maya devkitBase2020.4 plug-ins location]
2.open your maya project and load .mll
2.Prepare three sets of models
1.a reference model with main joints
2.a reference model with main joints and helper joints
3.a target model with main joints
*Note that the joint names of the three sets of models must be the same, and use different namespaces to distinguish them.*
3.Transfer
1.Select meshes in order prompted above
2.Select root joints in order prompted above
3.run command "De [sample numbers] [cone angle] [alpha] [if debug 1 or 0]"
Ex: De 128 30 3 1
