Hello, I’ve recently submitted a pull request for adding a new tool in the Rigbits that sets up gimmick joints easily. We have already had a Gimmick Joints menu to generate blend or support joints. but they can’t be regenerated with a new build rig. because of the lack of stored information. like its parent target, its side, and its gimmick type. This tool is designed to import/export them as a JSON file and include other utility stuff. Could you test it out if you have time? 
Thanks,
Here are the features of this tool.
-
Create gimmick joints
This feature allows you to generate “gimmick joints,” which can be either blend or support joints. These joints come with stored information in an extra attribute, enhancing their functionality and utility in your rig. -
Mirror gimmick joints (L → R).
With this tool, you can easily mirror existing gimmick joints from the left side to the right side.
This simplifies the process of ensuring symmetry in your rig. -
Select gimmick joints by side.
You have the option to select gimmick joints based on their side (left, right, or center).
This feature helps you work on specific sides of the rig more efficiently. -
Delete gimmick joints by side.
-
Import / Export gimmick joints in a JSON file
You can import and export your gimmick joints in a JSON file format.
This feature facilitates easy sharing and backing up of your rig setups, or call in customStep scripts
To access this tool, you can find it conveniently located under the “Gimmick Joints” submenu within the “Rigbits” menu.
