Face Lens Clipping
In the midst of creating a selfie lens experience and have run into some clipping issues, tracking around the head and hair of users, as well as face tracking. It doesn't make for a smooth experience, as of yet. Have shared the information and files with account representatives of Snap and they directed me here, as you are a great source of knowledge and should be able to assist here.
There is a lot of interference around the hair, as referenced below and video playback here.
Hi Miles, it looks like you are using segmentation in the video example you gave.
Can you please try adjusting the segmentation texture settings? It's not going to be perfect especially when factoring in long hair, different people and different lighting conditions. But you might be able to tune the segmentation to better match your experience. To tune the segmentation texture, select it in the Resources panel. Then, in the Inspector panel, try using the feathering mode instead and tune the feather amount. Review the segmentation reference here:

Unfortunately, beyond those settings, there won't be much you can do to improve the segmentation results.
Finally, in the screenshots you've attached, I'm a little confused what I'm seeing in comparison to the video. Can you explain how the screenshots differ from the video?
