CC Project Library in Project (New for v. 4.2)
You will have access to the new "2. Susan Expression Wrinkles Demo" project (Content > Template > All > Project > CC Project) after installing the "CC4 Projects" pack.
Both characters in "1. Talking Kevin" and "2. Camila Facial Demo" have expression wrinkles applied, but the latter contains animation to specifically demonstrate the expression wrinkles in action.
