Maya Proxy Attribute Tool

Proxy Attribute Tool is a simple Python tool for Autodesk Maya that allows you to quickly create proxy attributes—a smart way to link attributes between two objects, like a face control and your main rig controller.

Clean, user-friendly UI.
Select source & destination easily.
Add proxy attributes with one click.
Visual feedback directly in the viewport.

Tested in Maya 2024.2
Should also work in Maya 2020 and later (possibly earlier versions, but not officially tested).

Includes a README file with all the instructions.
