Splitting weights

Now that we've succesfully assigned the main brow shape keys to the face mesh, it's time to use these main shapes and split them into smaller regions by using the 3 curve principle. For this we want to use a geometry nodes setup in order to create 'linked' shape keys.

For Splitting the weights, we're using a geometry nodes setup to emulate 'linked shapekeys'.

You can simply append this setup by going to the top left menu:
