I more or less followed this tutorial -https://www.youtube.com/watch?v=VkVq8gm73SE
It entails adding an AR Face Manager to the Session Origin along with a face mesh prefab.
Hi, I’m trying to do face capturing on Xiaomi Mi9T and with the same setup you have it’s opening by default the rear camera instead of the front camera. Did you solved this problem?
[EDIT] Ok so I solved It by switching from Position and Rotation to Don’t Care in the Ar Session Script:), I’m using ArFoundation 4.1.5
