These are saved deformations of your 3D mesh representing different expressions or mouth shapes (e.g., 'A', 'E', 'O', 'M', 'F'). What are you animating

The auto lip sync blender software offers numerous benefits to 3D animators and video producers, including:

Assign your custom shape keys to the corresponding Rhubarb letter fields (A, B, C, etc.). Select your audio file in the panel drop-down menu. Click . If you are looking to take this further,
