ShapeKey Sync is an add-on that links the values of identically named shape keys across multiple objects in a scene. Located in the Object Data properties tab, the tool allows users to select a primary object and adjust a shape key, automatically applying the same transformation value to other objects sharing that key name.

The synchronization scope can be limited by selecting a specific collection, or left empty to affect the entire scene collection. An additional toggle controls whether objects within nested sub-collections are included in the synchronization. The add-on safely ignores objects that do not contain the matching shape key name.
