In this course, we will explain how to create VTuber models that support PerfectSync!
Perfect Sync is a feature that recognizes even the smallest facial expressions when tracking with the iOS camera.
nizimaLIVE, the official Live2D tracking app, supports Perfect Sync, so we will also show you how to set it up!
This is a must-see live lecture for those who want to take the facial expressions of their VTuber models to the next level.
Since blendshapes are mainly used in the creation process, this lecture is also recommended for those who want to know more about this feature!

For more detailed information on how to create facial expressions, please refer to the “Tips and Tricks for Creating Facial Expressions” video course, which you can watch together for a better understanding of the process.
