In the past, CG characters were always hard to escape from stiff movements and false expressions. This can be said to have been greatly improved in "Shrek 2". The "facial animation system" developed by DreamWorks is the hero behind the scenes. Its complex layering system can express the inner emotions conveyed by the characters' facial expressions.
The modeler first creates a skull for the character on the computer, then adds a piece of muscle, and finally skin. After skinning, the facial skin echoes the muscle control handles, allowing the animator to capture the desired expression. Shrek’s muscles have increased a lot compared to the first episode. There are 218 pieces on the face alone, and a controller called "megacontrols" is also applied to make complex expressions such as clenching the teeth and making subtle changes to the entire face. Achieved.
