Use the video of someone's face when they're using the effect as a texture in your scene, by extracting the face tracker texture. You can then apply the texture to a material and object - for example, to create a face swap effect.
To use the video captured of the entire scene, extract the camera texture instead.
You'll see an asset called facetracker0 Texture in the Assets panel:
The texture can applied to any material channel. Or, drag it in to the Patch Editor to use the texture in a visual shader.
The texture can be used in 2 different ways, depending on the effect you're creating:
To select either of these options:
3D Direct lets you create a 3D representation of the users face. You could then use this, for example, in a face swapping effect.
In this image below, we've extracted the face tracker texture and set the Copy Mode to 3D Direct. We've then applied it to a material, and applied the material to a face mesh:
If you want to create a face swap effect:
The face mesh will have quite hard edges. To blend these use the face mesh mask included in the face reference assets
In this example below, we've extracted the face tracker texture and set the Copy Mode to 2D Bounding Box. We've then applied it to a material, and applied the material to a plane:
You could use the 2D Bounding box mode to create 2D animations, featuring the user's face.
