Hi nice and smart people. I get crashes when the Face Tracker SOP loses tracking when my face exits the frame. Geometry freaks out and freezes.

Thanks for the report. Unfortunately I wasn’t able to reproduce the crash using your file and hiding my face - did you get a dump file as well when it crashed? If you could send that over we might be able to get a better idea of what happened on your machine.
As far as the behaviour when there is no face available: generally the face mesh should just freeze in the last pose when it cannot detect a face. However, the AI model can get confused when there isn’t a clear face in the image and try to lock onto things in the background (photographs or just random stuff) which can cause the mesh to jump around. You can use the “face1:valid” channel in the chop to determine if the current mesh is valid.
