I have been experimenting with this demo for a few years now. Maybe you've seen it in YouTube. The first time I did it, the old Blender Render engine was still around, and every time something new popped up in the release notes that could help me to make this demo better, I ended up making the sculpts, the animations, the textures and the hair from scratch again.

This version uses the newly released hair in geometry nodes, and it's quite more stable than the old particle-based hair system.

The rig has been remade again, and everything, shapekeys, UV layers, vertex groups and bones, have a properly english name (I started this project for myself and everything was in spanish)

Hope you can use it to understand how to integrate a rig with shapekeys and drivers to achieve an organic transformation effect.
