GeoNode Shape Keys stands out in the blender_extensions library for a specific workflow gap: sculpting corrections directly on linked and overridden characters. It's part of the Blender Studio pipeline scripts and released under the GPL v2.0 or later.
GeoNode Shape Keys is a Blender add-on from Mets that lets you deform linked and overridden meshes with sculpt mode, aimed at small corrections on an animated character. Its interface only shows on linked and overridden meshes, under Properties > Object Data > Shape Keys > GeoNode Shape Keys.
When you add a shape key you're prompted for a UVMap, which must have no overlapping areas within the object, and you can name the shape or let it default to the current frame number. You don't sculpt the original mesh: the add-on creates a duplicate and hides the original, and a button switches you back. The UVMap lets the GeoNodes set-up match the vertices of the real object with the local copy you sculpt on. Removing a GeoNode Shape Key entry also removes its modifier and object.
Selecting several objects before pressing the add button builds a sculpt object covering all of them, and an included operator creates non-overlapping UVMaps across an asset's objects. It's released under the GPL v2.0 or later and requests Files permission to load its GeoNodes from a .blend file.
GeoNode Shape Keys is best for making small sculpted corrections to animated characters on linked and overridden meshes in Blender.
GeoNode Shape Keys is completely free to download and use.
GeoNode Shape Keys is listed as compatible with Blender 4.2 LTS and newer. Version 1.0.0 was released on July 24th, 2024. One reviewer noted it was broken on a newer Blender build and hoped for an update, so if you're on a very recent release it's worth checking the developer's page for the current status before relying on it in production.
GeoNode Shape Keys shows its interface only on linked and overridden meshes. You'll find it under Properties > Object Data > Shape Keys > GeoNode Shape Keys, where an Add button starts the process. If you're working on a regular local mesh rather than a linked or overridden one, the panel won't be visible, since the add-on is built specifically for correcting linked assets.
GeoNode Shape Keys uses a UVMap so its GeoNodes set-up can match the vertices of the real object with the local copy you sculpt on. The UVMap must have no overlapping areas within the object; if your existing UVs overlap, you should create a separate UVMap for the add-on. For multi-object work, an included operator generates non-overlapping UVMaps across all of your asset's objects at once.
GeoNode Shape Keys installs the way other Blender extensions do: drag and drop the downloaded file into Blender, or download it and use Install from Disk. It requests one permission, Files, which it needs to load its GeoNodes from the add-on's .blend file. The download comes from the Blender extensions platform, and the developer's page links to the Blender Studio pipeline repository for the source.
GeoNode Shape Keys is released under the GNU General Public License v2.0 or later. It's listed as free here, and the add-on is part of the Blender Studio pipeline scripts maintained on the developer's repository. The GPL covers how you can use, modify and redistribute the code, so for the full terms, the source, and any redistribution details, check the developer's page linked from this catalog.
