Face Tracker

The face tracker tracks a single face in a scene and controls the position, scale and rotation of its children. It can also be used to drive a face mesh. You can have more than one face tracker in a scene.

You'd use a face tracker if you wanted to make another object move with or respond to a person's face. For example, if you inserted a 3D model of glasses, you'd need a face tracker to make sure that the glasses fit onto and moved with your face.



Uncheck this box to stop the face tracker and any children from being rendered in the scene.

Tracked Face

Choose the face in your scene that you want this face tracker to track. To add the ability to track multiple faces, edit the Face Tracking Capability (see below).


You can't change the transformations for a face tracker because it isn't an object.

Texture Extraction

Turn the points being tracked on the face into a texture.


Insert simple combinations of patches involving the face tracker into the Patch Editor.

Enable For

Choose the camera or cameras on a mobile device that you want to render the face tracker and its children in. Note that for the camera(s) enabled, the Find a face! instruction will appear whilst a face is not detected, but disappear while a face has been detected.

Face Tracking Capability

When you insert a face tracker into your scene, this capability is added automatically. Without this capability, you wouldn't be able to track a face in your project.

Multiple faces

You can edit the face tracking capability to include more than one face in a scene.

To add the ability to track multiple faces in your project:

  1. Click Project in the menu bar
  2. Select Edit Properties... > Capabilities
  3. Expand Face Tracking
  4. Edit the box next to Max Faces
