XSI Eyelid Rigging

XSI : eyelid rigging

This tutorial shows you how to easily rig any kind of
eyelid. It allows you to get a perfect shape that follows
the eye.

Here is a simple sphere for the eyeball and another one for the eyelid.
This technique is based on shapes, so we'll create a shape. We don't create the shape in a closed eyelid pose, no, we just push points forward without any deformation.
To give the eyelid the shape we want, select the corresponding points and apply a lattice.
Now you can deform the lattice to get the shape you want for the eyelid.
Here we are ! Try to animate the shape slider from 0 to 1 and see what happends, the eyelid closes perfectly. You can see an intermediate position on this image. To get different eyelid shapes, you can also create Clusters With Center on the lattice to animate it, or create shapes.
