1. Select master mesh within the plugin using eyedropper, all meshes selected next will link and create drivers using this mesh as the master mesh

2. Select all objects to be linked to master mesh (eyes, eyebrows, etc..) then click Create and link ARKit shapes within the plugin

3. All ARKit blend shapes are now created on master mesh and linked meshes. You only need to animate the master mesh, and the rest of the meshes will follow.
