Making dynamic face meshes with a variety of materials

To show an augmented face that matches your real-life expressions, Unity AR Foundation lets you generate a face mesh dynamically at runtime. On this mesh, you can apply different materials, giving the effect of you wearing arbitrary face masks. To add this to our project, we'll first look at the default face game object given by AR Foundation. Then we'll create several different materials to use. To integrate this feature into our project, we'll extend the ChangeableFace script to switch materials, add a similar function to the FaceMainMode script to update the face trackables, and then add menu buttons to switch materials.

Exploring AR Default Face

You can create a dynamic face game object for AR Foundation from the Unity menu at GameObject | XR | AR Default Face. The object includes an AR Face Mesh Visualizer component that generates a face mesh at runtime that matches your facial expressions, including moving...
