Earns its place in the Blender extensions library as a focused utility for the gap between Geometry Nodes and glTF, wrapping the duplicate, apply and merge steps into a few clicks.
Geonode To Shapekey is a Blender add-on from Jan-Hendrik-Müller that converts animated Geometry Nodes setups into shape key animations. The main use case is exporting Geometry Nodes animations to glTF, a format that supports shape keys but not Geometry Nodes.
The conversion runs in a few clicks. You select a GeoNodes object, generate duplicates at specific time steps, apply the modifiers, then merge everything into shape keys. The add-on can automatically keyframe either absolute or relative shape keys, and it renames and cleans up the scene as part of the process.
One constraint applies: you cannot add or delete vertices in the geometry nodes, since merging into shape keys requires the same number of shape keys at every time step. The add-on is compatible with Blender 5.1 and newer, requires no special permissions, and is distributed under the GNU General Public License v3.0 or later.
Geonode To Shapekey is best for blender users who need to export animated Geometry Nodes to glTF, a format that supports shape keys but not Geometry Nodes.
Geonode To Shapekey is completely free to download and use.
Geonode To Shapekey lists compatibility with Blender 5.1 and newer, and version 1.2.0 added support for Blender 5.1 specifically. If you run an earlier Blender release, the add-on may not function as intended, so checking your version before installing is worth doing. It installs by dragging and dropping the extension into Blender, or by downloading the file and using Install from Disk. The add-on also requires no special permissions when you enable it in your preferences.
Geonode To Shapekey cannot add or delete vertices within the geometry nodes setup. This is because the merge into shape keys step requires the same number of shape keys at every time step, so the vertex count has to stay constant across the animation. If your Geometry Nodes graph changes topology over time, the conversion will not work as expected. Keeping the mesh vertex count stable throughout the animated range is the way to stay within this limitation.
Geonode To Shapekey can be installed by dragging and dropping the extension directly into Blender, or by downloading the file and choosing Install from Disk in Blender's extension settings. Once enabled, it works on a selected GeoNodes object and requires no special permissions. The add-on is small at under five kilobytes, and it is distributed under the GNU General Public License v3.0 or later, with the source available on the developer's page.
Geonode To Shapekey is listed as free here in the catalog. It is distributed under the GNU General Public License v3.0 or later, and the source code is available on the developer's page for anyone who wants to review or build it. For the most current licensing details, checking the developer's page directly is the best approach. The add-on requires no special permissions when enabled in Blender.
