Hi! I’ve detected small flips in the eyelid small circular controls on our animations, only on the right side. The cause seems to be the parentConstraint of those control parents (eyeR_R_lowOutMid_npo, although it happens on the 4 of them), which flips its rotationY value from 0 to 180 at random when playing the animation.
Setting the parentConstraint to ‘noFlip’ instead of the default ‘average’ seems to fix the issue, but I’m looking into where this could come from, because each of them are constrained between 2 other controls whose orientation is consistent across all frames.
Has any of you experienced anything similar? I’m using Maya 2019.3.
