Character Library in Actor (New for v. 4.2)

After you have updated the Characters pack, you can find three templates: "CC4 Camila", "CC4 Kevin" and "CC4 Susan" with expression wrinkle effects under Content > Template > Item > Actor > Character.

The icon on the top-left corner indicates that the character has wrinkle effects.

Three templates for expression wrinkles can also be found under Content > Template > Item > Actor > Character > Clothed.
