What's difference between LIVE FACE (iPhone) for CTA3 and CTA4?

LIVE FACE (iPhone) function in CrazyTalk Animator 3 is only a facial mocap solution for iPhone X.
LIVE FACE (iPhone) profile combines with the Motion LIVE 2D Plugin for Cartoon Animator 4 for a total mocap platform which has more possibilities(for body or others) in the future. Cartoon Animator 4 has a 360 Head Creator function, allowing the facial mocap data through LIVE FACE (iPhone) to Cartoon Animator 4 to be displayed in 360° angle definition.
