Re-Drive is an add-on that automates the creation of drivers between custom properties and shape keys. When a custom property and a shape key share matching or similar names, the tool automatically generates a driver linking the two. This allows the custom property to control the shape key's value directly without manual setup.

The add-on supports multi-object setups. By selecting multiple objects with a primary active object, it will drive shape keys across all selected items that share the target names. It is particularly useful for recovering lost expression drivers in character rigging workflows, such as those caused by exporting through the Daz to Blender Bridge or using Rigify.
