2D Facial Rigging


Hi everybody,
Can anyone explain to me please how to achieve this type of rigging of the video below? Control curves that control textures?

I don’t know if the rigger of the video used textures. Basically, how to control textures and control textured imaged sequences to make the eyelids open and close for example.

Thank you


Sorry, your video seems to be private? Can you link it instead of imbedding it?
