Join Jason Baskin for an in-depth discussion in this video Working with eyelids, using in-between blend shapes, part of Rigging a Face in Maya.
…The linear nature of blend shape transitions can be…limiting, when working on certain regions of a facial rig.…For example, eye lids are often…problematic, especially for characters with larger eyes.…But Maya's in between blend shape option can…be a great solution for blend shape transitions.…Which require a carefully controlled path.…So I've created a left blink morph target for this character, and…you can see that it's sculpted so that it looks reasonably natural.…The eye is not cutting through the lid, or anything like that.…
And I've connected this target to the face.…And when I activate the target you can see that the blink works pretty well, but…in the midpoint of the blink the eyelid…actually cuts through the eyeball just a bit.…So, in order to correct this, I'm going to create an in-between…blend shape and plug it into this transition for a more natural deformation.…I'll select the Face Mesh and go to Edit > Duplicate.…And then I want to move it off to the side, since…this mesh has already been bound, I'm going to unlock the channels.…
