Can I improve the sensitivity of the Eye Tracking?

CA just gets better and better, but I have always had a problem with the eye tracking.

I've tried different lighting arrangements, getting closer and I just can not get a good consistent tracking of the eyes.

Even though I reset the Pose, when I look straight at the puppet, the eyes will move on their own. It is like auto blink for the pupils.

I've tried every, Eye Gaze setting I can, but never managed to get that constant following movement.

I have to pull a really weird, exaggerated face to get the movement anyway!

I do find a larger pupil works best, but that doesn't solve the issue.

Does anyone else have this?

Can anyone help with a solution?

Still a great app!
