Blender-to-ShapeKeys - Blender Animation Export Script

This Python script is a utility for 3D artists, web and game developers enabling export from Blender to other 3D packages.
Convert Blender-specific animations — like GeoNodes, Modifiers, Armatures — to more often supported animated shape keys.

Supported Platforms

Useful for platforms and formats that support shape keys, like:

• .fbx: Unity, Unreal Engine, Godot
• .gltf, .glb: WebGL, Three.js, Babylon.js

Key Features

• Mesh State to Shape Keys: Transfer Blender-native mesh modifications such as GeoNodes, Modifiers, Armatures.
• Set Stepsize: Choose number of generated shape keys, proportionate to the resulting mesh data size.
• Automated Keyframing: Effortless keyframe generation.
• Non-Destructive Workflow: Generates a duplicated object, leaving your original artwork untouched.

Limitations

• Consistent Vertex Count Required: Animations must maintain a consistent vertex count for every frame.
• File Size Increase: Exports to GLTF or FBX may result in substantial file sizes.
• Consider Efficient Engine Solutions: Explore more efficient engine-specific solutions or formats where applicable.

Installation & Usage

1. Choose your 3D object.
2. Open the script in Blender Text Editor.
3. Hit run.
