Where can I find a actual 'owners manual' for Character Animator?

You can create a separate layer with say an oval on it that you make invisible Make it bigger than the eyeball. Then put the pupil range tag on that layer Instead of the eyeball layer.

The idea deal is to give the pupil more freedom to move. My eye debugging blog had an ecample

Okay alank, I have corrected the problems of labels but the eyes still move inexplicably to the right or left corners.

But I still get the eyeball going to extremes for no reason. (The left eye has the exact layout.)

Pupil size goes on a layer to tell CH how big the pupil is. (Might actually be the iris, but lets not worry about that!). Pupil Range defines the bounding area the pupil can go in. So if Pupil Size is on the same layer as Pupil Range, the eye will not move (there is no space for it to move around in).  E.g. if you have a white circle with a black dot in it, the white could be the Pupil Range, the back dot would be tagged as Pupil Size. You can also fiddle with strength to limit it a bit.

If however you want the pupil to go outside the white area (e.g. its a large colored iris), then it can be helpful to create a separate circle for the Pupil Range and make it invisible. Gives you more control.

If you have excess tags - multiple objects with “Left Pupil Range” and “Left Pupil Size” then CH can go crazy. Same problem if you have non-contiguous artwork in those layers. CH does it best to work out what the eye is, but the eye can sort of jump between the areas. So you need to get those tags exactly right. Pupils can start going backwards for example if wrong. I think the internal maths goes negative at times or something. So I would strongly encourage you to make sure there is only one Left Pupil Size and only one Left Pupil Range tag in your puppet (And same for Right). Multiple tags can cause lots of problems.

I could not post the puppet here as it is not allowed to go this way. I could do it on a cloud system.

I have taken my glasses on and off but it doesn't have any effect on the puppet. The eyes still get really hyper-active with looking out the corners. The one oddity I could find was that both the right and left eyes there was a marking of 'right pupil size' 'left pupil size' on both pupils and pupil ranges.

I don't have any idea what pupil size means but I don't think I want it in there, do I?

This is the closest thing we have to a manual. It is quite frustrating when things aren't working the way you expect. If you post your puppet here(or PM me), I'm happy to take a look. My best piece of advice is to look at the behavior in the *Puppet* Properties panel. Here you can see the handles that the behavior is currently seeing. You cannot see these handles when using the *Track* Properties panel.

I help customers with puppets all the time and one of the most common problems is too many tags(e.g., multiple head handles fighting, often because a face background layer is named head as well as the head group) or layers/handles that are untagged, but should be(e.g., Eye Gaze not working because the pupils are untagged, maybe because they're named lpupil and rpupil)

Do you wear glasses? It might be light reflecting from your glasses causing problems. Or poor lighting on your face.

To test this out, go to the face behavior and disable the camera and enable the mouse as input for eye gaze. then try dragging the mouse around the scene window - do the eyes move reliably? If yes, its something about camera tracking. If no, read up on the crazy eyes section at the end of the blog post.

There are sensitivity and snap settings you can experiment with as well.

Books are normally note done by the platform - they are normally written by people trying to make a name for themselves in an area, or if a popular area they might make a profit from book sales. The probability of profit for CH is near zero because the audience is so small.

So what resources are there?

• The User Guide. Terse, but lists all features available.
• The video tutorials. Useful, includes examples.
• Udemy I believe has an online video course with tutorials (never seen it)
• Adobe MAX had a training session, but its a once a year conference
• The forums here - feel free to ask specific questions and see if others know an answer
• Blogs, videos, etc by community members (my blog is at https://extra-ordinary.tv/behind-the-scenes/ ; I have a YouTube channel linked from one of the latest blog posts)

But no books that I know of. The best way I can suggest is to ask questions here in the forum. A number of people jump on to help and the Adobe staff are here as well answering questions.

Regarding eyes, if you are having the problem, my blog has how I debug eyes (my most commonly referenced blog post).

That's all well and good but what can I do when the head won't tilt to the side? Ever! Or the eyes don't follow what you do? Perhaps when you buy a vacuum they put a list of the possible problems you might have and offer a few reasons why. If there were a book I could follow but this latest version is in a whole new ballgame.

At the top of the forums there are links to tutorials etc, including documentation. Otherwise try some Google searches! ;-). But there is a “User Guide” for character animator which sounds like what you are after. It lists each feature and the various properties.
