Pupils never recognizing eyeball/pupil range

Question

I'm still a novice, and I've been struggling with the pupils on multiple puppets where the pupils stray off. I was previously trying to make a pupil range layer and cover it with a different shaped eye, but only once I reduced the camera strength to 2% did it stay in the eye ball. I decided to just make literally the most basic one from scratch with regular identical white eyeballs and black pupils but still the pupils keep running off. I thought I was getting the hang of rigging and tagging all the parts correctly!

Also, while I'm sharing it, is there anything special I need to do with puppets that share the same head and body? Thanks for reading!

First, I restructured the puppet in Photoshop. You should have a root group for the whole puppet. I also did some little adjustments about independent layers etc. I started introducing the mouth in case you want expressions later, etc.

Notice I deleted the background layer as well. Otherwise it was just regrouping.

After that, I was still pulling out my hair. It was going crazy and I could not work out why. The pupils were going in the opposite direction, which told me it was a pupil range / pupil size problem (the size of the pupil was larger than the range causes this), but I could not spot it.

I finally worked it out. There are some stray pixels somewhere in the eye pupil layers. I don't know how to find them in photoshop, but I clicked on the Left Pupil layer, used quick selection to select the pupil, inverted the selection so it selected everything except the pupil (Select / Inverse from the menus), and hit DEL. This deletes any stray pixels outside the pupil artwork in the pupil layer. Repeat for both pupils and save it.

I then imported the PSD file to make sure I was starting a new, clean puppet with no stray tags. The eyes started working properly. (I normally test by turning off the "Snap Eye Gaze" property of the "Eye Gaze" behavior, and turn on mouse and touch input so I can look straight at screen and move pupils with mouse instead.)

So my guess is there are some stray pixels somewhere in the layer getting CH confused. I have no idea where, but if you follow the above it starts working. And yes, it was horrible and confusing to find because CH was showing the yellow outlines for everything was correct and appropriate... but it was lying.
