This course explains how to create a model that supports the “lip sync function” that responds to voice and speaks realistically.
We’ll explain in detail how to model a mouth that corresponds to the vowels “aiueo,” how to integrate it with existing tracking mouths, how to configure the tracking software, and even the physics calculations that make the movements look rich.
If you’re interested in singing covers or creating detailed lip movements, be sure to check this out!
