We did not plan on eye-movements or blinking eyelids, but still we wanted to include separate eyes in our Santa model. While real eye models would contain several layers and deformations, we opted for simple balls upon which we would later paint the iris. At the very least this would enable os to applye a separate more shiny surfaces to the eyes in a simple way. And should we later want to animate the eyes, this option would still be open for us...
