I developed a rigging tool box to help in repetitive and menials tasks while rigging such as : renaming, creating customs controllers, inserting joints, matrix constraints, FK/IK biped and quadruped rigging, space swap constraints, ribbon creation, and adding dynamics.
I made the UI in QtDesigner, and developed the script in python.
The project overall took two month on and off, and I intend to keep adding features.
The video demo is coming soon.
