Alternatively, if you supported its development on Ko-Fi, you will receive a download link in the confirmation email.

Updates to the Rigging Toolkit are released on a monthly basis, around the 5th of each month. If your version has expired there are two ways to get an update.

If you are an antCGi Club Member simply check the members only Discord channel or the YouTube community posts for the new link.

If you donated via Ko-Fi then you will need to donate again to receive the new link, via the confirmation email.

This error basically means that you are using the script in the wrong version of Maya, so a Maya 2022 script in Maya 2023 for example.

The solution is to source an updated version of the script.

Alternatively, if you have downloaded the Maya Script Pack, which is no longer supported, you can use the scripts found inside the “Source Scripts” folder as these aren’t compiled so should run in any version of Maya.
