Скачать или смотреть Maya - Paint Smooth Skin Weights

Download:
https://gum.co/maya-skinning-tools

Installation:
Extract the content of the .rar file anywhere on disk.
Drag the skinning-tools.mel file in Maya to permanently install the script.

Note:
The paint tool calls a script that find the surrounding vertices and its skin weights. These skin weights are then blended with the skin weights of the original vertex based value of the paint tool.
*Undo-able / Redo-able

Based on the settings on the skinCluster the following attribute will be respected while smoothing the weights:
Max Influences
Normalize Weights
Locked Influences

I would like to note that the idea for this script came from Tom Ferstl, he developed a script where the end results is very simular. I did use the original script as an inspiration, but what happens under the hood is completely different.
