The creatures on Pandora, the Na’vi, were created using motion capture to animate bodies and faces. At the same time, Weta linked the facial animation to the bodies, allowing Cameron to see the Na’vi’s facial expressions and lip-sync to match the actors’ performances. As soon as the actors started moving on the motion capture stage, Cameron was able to use the virtual camera to coordinate the shots while seeing the Na’vi in their environment with body movements and facial expressions.
