Rigi-All is a suite of tools dedicated to the building of a quick & easy Rigify rig from an existing model and rig. From game assets, for example. Every model deserves a great rig that animators deserve to use.
Rigi-All does not replace Blender's built-in Rigify add-on, but rather elevates its functionality with macros to make generating a Rigify rig as fast as possible. Therefore, Rigi-All requires Rigify to be enabled to use its rigging tools.
