Pet Head Tracker
Use Head Tracker to attach an object to your pet’s face.


In the Demo Effect sections, you will learn how to add a head accessory to your pet and wear hats with your pet. Start by downloading the following files:
Add a Head Tracker Object
Add a Head Tracker object by clicking the Add button [+] > AR Tracking > Head Tracker in the Hierarchy panel. The Face Binding component is included when a Head Tracker object added.
Adding a Head Tracker object will add a Head object by default. The Head is parented under the tracker object so that it follows the head movement.

Cat Head Occluder Model
The Head object is a head-shaped mesh with Occluder material that allows you to mask the onscreen head. You can download the head occluder model for 3D scale reference here:
Configure a Face Binding Component
Click the Face Binding object in the Hierarchy panel. Locate the Face Binding component in the Inspector panel.
Configure the Face Binding component:
- For Which Face, select the number of faces you want to attach to the effect.
- Change the Tracking Target to Cat.


- Learn more about Face Binding.
- Face Binding does not currently support dog face tracking. However, the algorithm may sometimes consider a dog as a person, so some human face tracking features may also work on a dog’s face.
Put a 3D Object on the Head
Navigate to the Hierarchy panel and click + > 3D > Sphere. To ensure that the object follows the head, you need to parent the sphere object under the Head Tracker. Then it will follow the tracking head movement.
