KMJ DUPLICATE COPYWEIGHT

In MAYA, if you edit the mesh after skinning by adding edges or merging vertices, you will get a history.

And when you try to adjust the weights as they are, I'm like, "Non-linear? Can I eat it? It won't work because the vertex order will change.

This is a script to organize the history while keeping the skin weight in such a case.

FEATURES

● Delete history while retaining weight 

● Duplicate while keeping the weight 

● Delete non-deformer histories while keeping the weight 

● Copy weight to an unbound mesh 

● And freeze translate, rotation, scale, and pivot

PRECAUTIONS 

● Multiple meshes selection is supported, but hierarchical selection is not done. 

● Meshes without skinCluster will be ignored (you can use "Copy to Non-Weight Meshes" to copy the weights separately) 

● The "Delete Non-Deformer and Keep Weight" is broken when undoing it. 

● Vertexes with different weight values cannot be successfully copy-weighted if they overlap.

UPDATE

2023/10/10　Reverted due to a bug

• Changed copy method for duplicate and history delete copy weights.Weight copying of vertices at the same position has been improved.

2022/08/10

• Fixed to work with Maya2022 (Python3).

2022/07/08

• Fixed a bug that sometimes prevented attributes from being unlocked.

2020/05/27

• Fixed that the freeze setting did not work.
• Fixed skin clusters disappearing when applying a deformer such as Lattice to multiple meshes.

MAYA Versions

You can use this script for both commercial and non-commercial work.
