Currently making a school project for youtube with vtuberisk style using adobe ch, and well, i've had a lot of issues with the eyes of this model, lots of research, learning and so on, but for the life of me i can't seem to figure this one out, i followed this simple written tutorial page, done everything as told also above and beyond of whats told, my current 2 problems are
1) For whatever reason my animated blink doesen't work when im facing directly the camera, also the closed blink state gets stuck every now and then
2) How do i make seperate eyelids behaviour from eachother, for example only closing one eye partially etc.?

 

-i have attached a gif of my blink problem below.

I am not sure, but some suggestions. 

I would try adjusting the light on your face. In the video one side is a bit darker than the other - I was wondering if that is confusing it (in which case you will find nothing i. the puppet itself!)

 

Blink layers normally fire instead of using eyelids to close eyes. I wonder if actually you don't want blink and just use eyelid closing instead, so you have finer control. But that would require different artwork.

 

I was not sure why you had the cycle layers pause tag on one of the layers in a screenshot. I don't think you need that.

 

You could but a keyboard trigger on the blink layers and try turning off the camera. Does it behave correctly then? If not, then it's not the webcam. Might help narrow down the problem.

 

I personally would go through every layer in the rigging hierarchy and check all the tags. A stray tag or a Left tag on the right side can causes havoc.

 

There is nothing wrong with that page you mentioned, but here is a blog i wrote a few years ago in case anything useful in it. https://extra-ordinary.tv/2018/04/21/debugging-character-animator-eyess/

 

But the fact that things work better for one eye than the other makes me think lighting or stray/wrong tags.

    For g*** sake adobe let me post this, i just want to learn and work, how can a multimillion dollar platform be this badly bugged in every program and even on their own msg boards.

     

    Alrit, so i got it almost completely working, the eyelids layers are just acting quite whacky, is there a way to make them less responsive or harder to trigger, for example, currently im practically not making eny expression, yet the eyelids wander around? Tried to adjust eyelid strenght, but all it does is limit how close they can get to each other. And with default value of 100% it deems me as chinese and almost keeps my eyelids perma shut. Also the blink seems to work only occasionally or every other blink, i have a 6w 2600K led bulb almost pointed at my face and yet it can't seem to pinpoint my eye movement normally -.-.... Damn racist piece of code xd.

    Personal opinions here. I don't use the eye tracking from a web cam for anything (eyelids, pupil direction, etc) because of jitter. It does work, but I like more reliable control. Note: i use it for recordings, not live streaming, so i care more about recording with precision than live ease of use. So I use keyboard triggers whenever possible, with autoblink, then cycle layers for blink sequences. I use the mouse to control where eyes are looking. It is less flexible, but you can have multiple triggers for different eye expressions. 

     

    There are other features you can use - like clipping. At the end of the video your eyelids were coming out the top of the head. You can use clipping masks to stop this if you want to. But if you want live with eyelid web cam control, you can livestream etc, but the quality will be less. I think you just have to chose between the two.

     

    Note I see this jitter with many such tools, not only Character Animator. The technology is getting better, but it is not perfect.


    Oh, actually one question more, is there a way to make these bottom eyelids not come on top of the eye's by default, without adjusting the eyelid strenght?
