Using two different AR Sessions Type at the same time

Hi there,

I am working on a personal ios app where I would like to have a character tracked in space and at the same time using the face AR for facial mocap.
Is it possible to use two different AR Sessions Type (like World and Face) at the same time?
At the moment I have this basic setup, but it’s not working. Each AR Session is working fine if I use one alone.

Thank you,
Francesco
