Shapekey Cleaner Pro - Fix & Clean Shape Key Deformations

ShapeKey Cleaner Pro supports Blender 3.0 and up, and the listing covers versions 3.0 through 5.0. It requires a mesh that already has shape keys, since the addon works by cleaning existing shape key deformations and resetting selected areas back to the Basis shape. Make sure the shape keys you want to clean are in place before running it. Within that version range, the listing marks the addon as compatible throughout, which helps if your project spans multiple Blender releases.

ShapeKey Cleaner Pro includes a Batch Cleanup Mode that cleans the selected area on all shape keys at once, which suits fixing broken facial regions across an entire morph system. For working with large libraries, a Shape Key Search field filters by name in real time and is aimed at projects with 50 to 200 or more shape keys. You can also build reusable masks from vertex groups to clean the same area across multiple shape keys without redoing the selection each time.

ShapeKey Cleaner Pro lets you select a region of a shape key and reset its deformation back to the Basis shape with a single click, so you avoid manually editing vertices or recreating shape keys. You can preview a shape key's deformation before cleaning it, and every action works with Blender's undo system. Reusable masks made from vertex selections let you apply the same cleanup across multiple shape keys, which helps when managing large facial rig systems.

ShapeKey Cleaner Pro is listed as free here, and the source lists it under the GPL license. Because pricing and terms can change over time, check the developer's page for the current licensing details before downloading. The addon works on any mesh that already has shape keys, using selection, mask, and batch tools to reset unwanted deformations back to the Basis shape. It requires Blender 3.0 or newer, with the listing covering versions up to 5.0.
