Photorealism isn’t always the goal with 3D animation. In fact, stylized looks are very popular- the sketchy look, cartoon renders, the list goes on and on.  But occasionally we need something to look totally real. That’s really rather easy with most non-organic textures, although it can still be costly to create because of the render times and equipment required.  But eyes, hair, skin… truly believable faces- now that’s a challenge.  But we have just about locked these hurdles up.  Check out this eye animation after the break.  It’s crazy realistic.
