OK, here's what I came up with. Turns out I was off on the hierarchy I posted before; if you child the eyelid to the eye, then you can't rotating the eye without rotating the eyelid. What worked better was a variation on Geek's "Pac Man" technique, I parented the eye and top lid to another EyeLid object that functions as the back of the eye. I also ended up using more than 3 keyframes, but I think if I understand how the tweener controls worked better, I would have done it with fewer keyframes. Anyway, these are me experiementing with slow and fast blinks, with different pupil sizes. According to the book I'm reading, fast blinks are supposed to make a character look more intelligent and alert. Slow blinks make a charcter look dumber or sleepier. The book also suggested that slow blinks work better if the pupil moves down with the eyelid. Also according to the book, the larger the pupil the more friendly and open a character looks, while smaller pupils make the character seem more detatched. Dunno. What do you think?
