Ways to fix glasses-related issues

[TrueChaoS]

Hey everyone, sorry I've been inactive recently (Steam related issues)

I've noticed that while I way away, there have been a number of people having issues with glasses causing eye tracking bugs, so I thought I'd make a thread specifically to address this.

Keep in mind, these fixes are only work-arounds and will not fix the core problem, but it's better than nothing. If you have glasses and don't have any issues with eye tracking, this is unnecessary for you to do. This is just for people who have issues.

Disable Blinking

One of the major issues that glasses can cause is the program misreading your eyes (often because of glare) and assuming that you are blinking when you aren't. To fix this, go to "Customize Avatar", click on the "Special Actions" tab, and then scroll all the way to the bottom. There will be a box ticked with "Enable Blink" beside it. Untick this box.

By doing this, FaceRig will not attempt to make the character blink every time it thinks you do, which can drastically improve your experience if you have glasses.

Widen your eyes

Another thing that make cause issues, such as a "lazy eye" appearance, is that FaceRig misreads your face thanks to your glasses obscuring your eyes a little. This can result in the program thinking your eyes aren't open properly.

To fix this, go to "Advanced Face Tracking Calibration", click on the "Expression Units" tab, then adjust the parameters for "Left Eye Closed" and "Right Eye Closed" to compensate for the tracking errors your glasses are causing.

If adjusting the parameters doesn't fix the issue, you can also completely disable these two tracking options, though this will make it impossible for your eyelids to move.


Ultimately, there's only so much that can be done if your glasses reflect too much light from your monitor, but these steps should help compensate for these problems.

If the tracking affect the eyes position you can enable look at the camera option.

This will likely help as well, thanks for mentioning it :3

Also when you look at the videos that folks have posted online using glasses, you will notice that where it works best, one of two things is happening (or both)

- they are using rimless glasses ( or very thin rim glasses)
- the lens reflections are not strong ( wither the ambient light level is high enough so the monitor reflections on the lenses cannot compete with the ambient light, or the angle of the camera is set-up as to avoid monitor reflections).

Oh this is awesome. Thanks so much for this! I lucked upon another post that linked to this. My first time using this program, I noticed one of my eyes was droopy and weird or something. I didn't realize it was because of my glasses.

Is this something that can be fixed in the software or is it another stupid affect of having to wear glasses? They've annoyed me most of my life. I don't blame ya guys or anything. Lots of stupid glasses issues!

I wear glasses, and I do have to change a few settings described in the part about "Widen your eyes" but after that it works perfectly for me.

One tip though, after you have calibrated, make sure to save it, so you can re-load the settings quickly next time.

For Widening Eyes, how exactly do the interval input and smoothing options work? What do the bars mean?

The three bars indicate the two "key" steps in the animation, and your current position in it based on how the program is tracking your face.

The Red bar and Green bar are the two stages. For your eyes, the Red bar indicates "completely closed", and the Green bar indicates "wide open".

If you watch the bars when you open and close your eye, you should see the third one move left and right. What you want to do is close your eye, then move the Red bar so that it is above where the indicator is. Now, whenever your eye is closed enough that your "current" position is past the Red bar, the character's eye will closed.

When you widen your eye, you should see the indicator move to the right side. If you move the Green bar under it, the character's eye will be completely open whenever your eye is open far enough for it to push your current "indicator" over where you set the Green bar to be.

If you want to force the character's eye to always be open besides when you close your eye completely, you can set the Green and Red bars to be right next to each other. That way, your default state will be wide open, and whenever you close your eye, your character will close them.

As for the Smoothing, I'm not entirely sure >< haha.
Someone else will have to answer you on that one.


I'm sorry if that was a little hard to understand ^^
Don't have the time to take screenshots and crop them down right now (lots of messages to read). If I lost you anywhere on that, just let me know and I'll make some spare time to get pictures.

Smoothing is the speed between transitions.
For example, without smoothing, the would "snap" from one state to the other, and the more smoothing, the longer it will take to get to that state.
For eyes you usually want a low amount of smoothing, to be able to blink fast
For mouths, you want a larger amount of smoothing, since those movements are usually a lot slower.


edit by TrueChaoS: fixed that quote error for you~

Excellent. Thanks so much!

Also this guide may further help you :) http://steamcommunity.com/sharedfiles/filedetails/?id=315322209

It is worth mentioning that there are users with glasses for which FaceRig does work ok (could it be the photochromatic lenses that prefect lens reflections?)

I could just do without my glasses but my problem is that my eyes are naturally kinda squinty and take a lot of effort to actually keep them wide enough to register. and when i try to wink with just one eye it doesnt even register my eye even closes. idk what to do.

A proper initial calibration with your eyes in a relaxed position should be enough to solve all the above :). The fact that you need to make an effort to keep them wide enough to register typically means you didn't really do a good initial calibration :)

If that is not it, just make a thread with a detailed description for your issues, or even capture a short face-cam video that start with a few seconds of neutral expression and send a link to us at info[at]facerig[dot]com , we'll take a look let you know what you are doing wrong :)

well I thought I did the calibratios right like they showed me in the video but I guess what I mean is my eye in a natural way look closed. I'll do as you said though and make my own thread

Remember if you can to send us that face-cam video, there may be other aspects that you are not considering important to describe to us, but they might be and they will become apparent from the video.
