Tracking More Than One Face

Tracking More Than One Face

You can add more than one face tracker to a Spark AR Studio project, to create an effect that can be used by more than one person.

Adding a second face tracker

The first face tracker you add will track the first face that appears in the scene.

You'll need to assign a face to every other face tracker you add. To do this:

  1. Select the face tracker in the Scene panel.
  2. In the Inspector, change Tracked face. For example if you've added a second face tracker, you'd change the Tracked face to Face 2.

Adding more face trackers

Each time you add a face tracker, an additional Face will be added to the Tracked face dropdown list.

Assign each new face tracker to a different Face.

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