Study Notes

Face Tracking and Effects

Use face mesh mode for applying textures in face swap effects.
2D bounding box mode creates a flat face cutout for 2D animations featuring users.
Enable opening and alignment by checking Eyes and Mouth for proper texture alignment with face mesh.

Creating a Face Swap Effect

Begin by adding two face trackers to the scene; rename them face_1 and face_2.
Set the second face tracker to respond to the second face by selecting "Tracked Face" to Face 2 in the Inspector.
Extract textures for each face tracker, create two face meshes as children of the trackers, and develop materials with Flat shader type.
Apply each face texture to the material of the opposite face in the scene.
Blend hard edges of the face mesh with a face mesh mask from reference assets.

Segmentation Types

Person segmentation: Isolates the person with the effect from the background.
Hair segmentation: Distinguishes a person's hair from other scene elements.
Skin segmentation: Isolates skin detected by the camera.

Hand Tracking

Use hand tracker effects that react to hand movement and position.

Types of Effects in Meta Spark Studio

People effects: Responsive to movement and involve capabilities like face, hand, body tracking, and person segmentation.
World effects: Introduce virtual objects to real environments; typically utilize rear-facing cameras through plane or target trackers.

Face Tracker and Face Mesh

Face tracker detects position and orientation of a person's face; combines with a face mesh for tracking facial movements.
The face mesh is a 3D model reconstructing facial expressions.
To add a face mesh, use the Scene panel to insert it; a face tracker will be added automatically if missing.

Applying Materials to Face Mesh

Create a mask effect by applying a material to the face mesh; do this through the Inspector to attach a new material.
Face mesh mask texture aids in fading material edges for better blending with the face.

Texture Creation and Usage

Use grey-toned templates (faceFeminine.jpg, faceMasculine.jpg) to create custom textures for face effects.
Extract a video of a user’s face as a texture in the scene using face tracker texture extraction for face swap effects.
Texture can be applied to any material channel, ideally as a flat material or in the Patch Editor for additional visual options.

Copy Mode and 3D Representation

Two copy mode options available; choose 3D Direct for a three-dimensional user face representation.
