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
• Delete unwanted shapeOrig nodes

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.
• We are not liable for any issues or damages arising from the use of this script.

UPDATE

2024/10/25

• Fixed errors in models created with older versions of Maya.

2024/09/12

• Changed to return to bind pose once before execution

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.
