I wasn’t in class today as I am coming down with a cold and didn’t want to infect anyone but I will catch up on work.
we learned about using shape keys and drivers. shape keys can be used to make facial expressions, they are kind of like blend shapes in Maya. and drivers are kind of like controls in they are bones that are adjusted to look different (used circles in the video) Then you put a limited location constraint on it and link it to a shape key so you can just adjust the driver, instead of going into the shape key menu and adjusting it there.
