Question

I've Got Dreamy Eyes....

I'm just working on the eyes... getting to know what impacts on them...

But, I'm now stuck with dreamy eyes.. if you watch the video, you'll notice that I reset the pose... but the eyes start wondering up... even though I keep a fix position!?

It could be something I'm doing, but the up and down movement of the eyes is certainly more noticeable .. It seems that the Tracking is more in tune with the up and down movement of the eyes, than the side to side? Is there any adjustment for up and down and the right to left axis?

I've tried making several adjustments... but even if I just stare straight... the eyes start moving up... any suggestions welcome?

    What eyeball shape do you have below the eye cutouts? Changing that might change the pupil bounds. I'd also play with the eye gaze camera strength. Worst case scenario, I usually do one camera pass with camera tracked eyes and then add/blend some mouse-tracked eye movement over top.

    Hi Dave...

    The Eyeball shape I started with, was a circle, but the Pupil was going too high, or too low, so I made it more oval, as in the image...

    and this help restrain the pupil.

    As the Eye Gaze and Face behaviors impacted on the eyes.. I tried adjusting them.... I found that setting Eye Gaze Smoothing at 25% and Camera Strength to 59%... seemed to work best... What does the camera strength do?

    With the Face settings, it was more hit and miss... I didn't really know which behaviors was having an effect unless I adjusted them quite a lot.

    I take it the smoothing just slows the transition from one state to the next?

    As there is only one Smoothing option for the Face Behavior.... I assume this impacts on all the setting within the face?

    When I move up and down, or in and out.. the eyes do tend to bounce... I suppose this could be something to do with latency from picking up the single to outputting the result, or just an aligning issue between the camera and head position?

    I hoping to get to point where having to do additional takes will be the exception, rather than the norm!?

    Camera strength changes how much the eyes should move based off of the camera. So if you're not getting enough movement, bump this up. If you're still not getting enough left/right movement, you could also try making the eyeballs longer (since they're hidden below anyway). That will give them more space. A test I like to do is arming Eye Gaze > Mouse & Touch Input and then dragging to see the full range.

    Yes, smoothing makes the animation less jittery; at max it will feel more slow and floaty. And yes, the Face smoothing will affect everything in those Face properties.
