Face Mesh

The face mesh is a 3D model of a face. It works with the face tracker to create a surface that reconstructs someone's expressions.

Once you have a face tracker and face mesh, you can apply a material with a texture to it - to create effects like masks or retouching, or to change the shape of the face.

The face mesh has to be the child of a face tracker. If you add a face mesh without a face tracker, a face tracker will be added automatically.

Including multiple faces meshes in a scene will impact the performance of your effect. If you're layering simple face meshes, for example using our default material and a texture, it's best to avoid layering more than 5.

Inserting a Face Mesh

To add a face mesh:

  1. Click Insert in the Toolbar.
  2. Select Face Mesh.

When you select a face mesh in the Scene tab, you can make changes to it by adjusting its properties in the Inspector panel.

Face Mesh - Properties


Uncheck this box to stop the face mesh from rendering in the scene.

Face Tracker

You can have more than one face tracker in the scene. Choose which face tracker will drive the face mesh.


Choose whether you want the face mesh to have an opening for someone's eyes, or not.


Choose whether you want the face mesh to have an opening for a mouth, or not.


Edit the position, scale and rotation of the face mesh.


Choose the material you want to apply to the mesh, or create a new one.


Make changes to the shape of the face, using blend shapes you've created in 3D modeling software. Find out more about deforming the face mesh.

Morph Object

If you want to deform the shape of the face, you'd apply the blend shape here.

Blend Shapes

Use the slider to change the appearance of the face, if you've applied a blend shape to your face mesh.


Insert simple combinations of patches into the Patch Editor, like tap gestures.

Enable For

Choose the camera or cameras on a mobile device in which you want to render the face mesh
