ZV Radial Blend Shape is a deformer node particularly useful for facial animation.
Through the use of shapes it gives you complete control over your character deformations and enhances shape blending by adding two extra shape-driven parameters.
ZV RBS makes eyelid and eyebrow deformations extremely easy to setup!
The radial blend shape node in this video uses one shape target per eyelid (4 in total).
The target weights are left unpainted, since I didn't find the need for that.
