Facial capture uses the camera to capture facial movements and reflect them on the 3D virtual character in real time.

1. Go to【Tracking】-【Webcam】;
   
2. Turn on the corresponding switch to control face capture, and the system will automatically link the camera and sensor after turning it on.
   

The description of the tracking configuration options is:

• Facial Tracking: Whether to turn on the face capture detection, after turning it on, you can intelligently capture facial expressions through the camera;
  
• Head Tracking: Whether to turn on head detection, after turning it on, you can intelligently capture head behavior through the camera;
  
• Upper Body Tracking: Whether to enable upper body detection, after enabling it, you can capture upper body movements through the camera;
  
• Display Webcam Feed: Whether to turn on the camera feedback, after turning it on, you can view the capture effect in real time;
  
• Tracking Auto-Calibration: Whether to enable the automatic calibration of the camera, after enabling, the system will recalibrate the anchor's surface capture position to make the capture more accurate.

When you make facial expressions, the avatar will make the same expression in real time. If head capture is turned on, while shaking your head, your avatar will also shake your head at the same time; if upper body capture is turned on, while your upper body is moving, the avatar will do the same movement.

1. Select the camera driver currently in use.
   Look! I have three cameras, and this time I chose "USB Camera" to use.
   
2. Please confirm whether the camera driver you are using is occupied by other applications. If it is already occupied, please release it first.
   
3. If you don’t have a camera, you can use your phone as a PC camera. The recommended software is ivCam[www.e2esoft.com].
