Shapekeys Extended earns its place in the superhive library by reworking Blender's shapekey panel into a hierarchy-based system and folding in tools like Pose to Shapekey and face tracking presets that the default panel doesn't provide.
Shapekeys Extended is a full overhaul of Blender's shapekey system, keeping every default option while layering on new functionality and quality-of-life changes. The UI moves to a hierarchy layout with collapsing groups, lets you move and reorganize groups of shapekeys, and adds new shapekeys below the current selection rather than at the bottom of the list. All features work in edit mode, and a Copy Shapekey button duplicates the data from the selected shapekey into a new one.
Extra menu options include Invert Shapekey, Copy and Split Shapekey, Remove Empty Shapes, Clear Shapekey Weights, and Normalize Shapekey for remapping a modified range back to 0-1. Additional tools cover Pose to Shapekey, Remove Shapekey Influence for selected or all vertices, applying modifiers on meshes that already have shapekeys (optionally keeping the armature modifier), and an Add Facetracking Shapekeys section with presets for Vive, ARKit, Meta, UnifiedExpressions, and MMD. An N-panel gives quick access to the tools.
The add-on is released under the GNU GPL 3.0 license and is actively in development. It's listed here as free, and a demo video is available.
Shapekeys Extended is best for blender artists organizing large sets of shapekeys and building face tracking setups for standards such as Vive, ARKit, Meta, UnifiedExpressions, and MMD.
Shapekeys Extended is completely free to download and use.
Shapekeys Extended installs like a standard Blender add-on. Open Blender and go to Edit > Preferences > Add-ons, then use the install option in the upper-right corner and select the downloaded ShapekeysExtended-CasTools .zip file. Once installed, find it in the add-on list and enable it. To use it, select and make active an object, then open Properties > Data > ShapekeysExtended, which sits in the same location as the normal shapekey panel. You may need to scroll down and drag the panel higher in the list to reach it.
Shapekeys Extended includes an Add Facetracking Shapekeys section that lets you choose from a list of common face tracking standards. The supported options are Vive, ARKit, Meta, UnifiedExpressions, and MMD, with MMD offered in both Japanese and English versions. You pick a standard from the list to add its face tracking shapekeys. This section sits with the add-on's other tools, reachable once the ShapekeysExtended panel is open under the Data properties of a selected object.
Shapekeys Extended makes all of its features, both the older standard options and the newly added ones, work in edit mode. Alongside this, new shapekeys are added below the current selection rather than at the bottom of the list, and a Copy Shapekey button copies the data from the currently selected shapekey into a new one. These sit within the reworked interface, which uses a hierarchy layout with collapsing groups and lets you move and reorganize groups of shapekeys for cleaner organization.
Shapekeys Extended is listed here as free, and it's released under the GNU GPL 3.0 license. For the current terms of use and any licensing details, check the developer's page, since those terms can change over time. The add-on is also noted as being actively in development, so bugs may exist; the developer asks that any issues be reported through Discord or Blender Market so they can be fixed.
