I started working on an eye rig solution based on Marco Giordano’s work. All credit goes to him for coming up with it. I had seen it once before, but learned the technique through Wade Ryer’s course. The setup works by having locators ride a curve and joints pointing towards those locators. When you then deform the curve, the locators move, which in turn move the joints, which in turn moves the skin. The beauty about this set up is that it really feels like the eye lids are sliding over the eye ball. I’ve added some driven behavior for looking up, down, left and right and the whole things feels really good when you move it.
Because this is something I’d like to add to more of my rigs, I started scripting out the process. I’m still working on it, but wanted to add a little update on the whole thing anyway 🙂
