Following today’s tutorials I was able to play a bit with using blend shapes which is super fun! The animation itself is pretty bad but this was more for the purpose of learning.
I made a little Nurbs controller and limited the movement so it couldn’t move outside of the parameters of the blinking.
It also seems as though you do not need to use the sculpt tools solely for blend shapes and can manipulate by moving faces, vertices and edges. however extruding is not a good option.
Its also cool to note you can add in-between targets if the eyelids go into the eyeballs for example.
