I don’t have much experience rigging, but I was able to throw together a simple eye rig. The eyes are set to aim towards a null, and the eye lids are set to dynamically orient themselves to the pupil. The problem is this: when the null that drives the eyes crosses the XZ plane, there is a little popping of the eye lid rotation as it crosses the threshold from 1 to -1 on Y.
I know that this may be due to the “priority” of the constraints and XPresso, but did not know where to start.
Any and all help would be much appreciated.
