Eye Rig Popping

[Mark Walczak]

Hi everyone,

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.

Thank you!
