Tracking More Than One Face

You can add more than one face tracker to a scene, to create an effect that responds to more than one face.

The first face tracker added will track the first face that's detected by default. You'll need to assign a face to every other face tracker:

  1. Select the face tracker in the Scene tab.
  2. In the Inspector panel, change the Tracked face.

For example, set Tracked face to Face 2 for a face tracker to track the second face that's detected by the camera.

Adding more face trackers can have an impact on performance, so it's good idea to test your effect as you build it using the Spark AR Player app.
