Unity Face Tracking - No Data - Orbbec Astra Pro

We followed the recently published tutorial from the NUITRACK blog -including the steps of enabling facetracking in the config file.
However, when we run the application in unity the JSON data only has a timestamp, no face data.

Any ideas why this might be the case?
Is it possible to get a functional Unity project for the face tracking example?

Hi ondatabc,

You have to enable RGB stream for Astra Pro: set “CameraID” value in the nuitrack.config file (usually it’s 0, but if it doesn’t work, try 1, 2, …).
