    The Livelink connection in the FaceAR sample project is not linking?

    We have followed the instructions for setting up the FaceAR Sample project ( and have everything running.

    However the Livelink does not seem to be activated: the Windows 10 app does not show any updates the iOS app should be sending out.
    iOS does detect the face and updates within the app.

    -> Both machines are on the same network and should be able to see each other. (Check with a small setup using OSC communication)
    -> Tried this in 4.20.3 and 4.22.1
    Do we need to add any special rules to the (Windows default) firewall?

    In the docs ( it says:
    "Launch your Project, and in Project Settings set Supports AR to On."
    Searched back and forth but I cannot find this setting in the project settings, can this be the cause?

    Thanks in advance for any tips which will push us in the right direction towards a working setup.

    (cross posted here as I didn't know where to place this)

    For those ending up in this subject: one thing we found out: when the iOS app is build in 4.22, the Windows side also need to be running 4.22. A project running in 4.20 will not (properly?) receive any Live link input.


      If you go on settings in the FaceAR app on the iPhone and choose the LiveLink connection, then with the correct ip-address, tap connect.

      So, every time it doesn't connect just tap connect again on the phone. I have to do it all the time.
