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.
