When I create an eye that is a perfect sphere everything is easy, the eyelids and iris move around the surface without issue. But when the eye is more flat or oblong, it confuses me on how to animate it. One trick I’ve found is if I start out with a sphere and then scale just the bones until the eye is the desired shape, it will still animate as if it were a sphere as long as I don’t apply Rotation & Scale.
My question is, can I animate like this and import it into a game engine somehow? I have only a basic understanding of rigging, but from past experience trying to animate it seems as if not applying rotation and scale to your bones causes issues.
