Using the texture in an effect

The texture can be applied to any material channel. It's a good idea to use a flat material. Or, drag it into the Patch Editor to combine with other visual shader patches.

If you select the texture in the Assets panel, you'll be able to see and edit its properties in the Inspector.

Copy Mode

There are 2 options to choose from here.

3D Direct

Use this option to create a 3D representation of the user's face. You'd generally use this mode when applying the texture to a face mesh, for example in a face swap effect.

2D Bounding box

This mode will create a flat cutout of the face. You could use this mode to create 2D animations featuring the user's face.

Enable Opening and Alignment

If the texture is applied to a face mesh, check the boxes next to Eyes and Mouth. This will make sure the texture aligns properly with the face mesh.

Creating a face swap effect

Start by adding the face trackers:

1. Add two face trackers to your scene.
2. To help keep track, rename the face trackers - name the first face_1, and the second face_2.

Then, edit the second face tracker so that it responds to the second face to appear in the scene:

1. Select face_2 in the Scene panel.
2. In the Inspector, set Tracked Face to Face 2.

Next, create the face mesh, textures and materials:

1. Extract the face tracker texture for each face tracker.
2. Create 2 face meshes, each as a child of one of the face trackers.
3. Create a material for each face mesh, and set the Shader Type to Flat.
4. Apply each face texture to the material applied to the opposite face tracker in the scene.

The face mesh will have hard edges. To blend these with the face, use the face mesh mask included in the face reference assets.
