Key Copier

A Key Copier tool for Maya.
This tool is designed for loops, allowing you to set a start and end range then copy keys from one end to the other.

With the UI enabled you can choose whether to use the selection, all animated objects or a specified selection set, as well as some other options. Once you have the settings to your liking, you can use the tool as a shelf button without UI to quickly copy one end of your loop to the other, in order to ensure they match.

Tested on Maya 2020 and 2023. Should work on most versions, but if you encounter any errors or bugs please reach out to me and I'll provide a fix.

Key Copier is free because tools should be accessible. However, if you wish to support the development of future tools and find this one useful for your workflow, please consider setting a price to cover a coffee or two :) Thanks
