Cute Pin-Up is a pack of expressions organized in three folders (FullFace, UpperFace and LowerFace) for The Girl 6, a premiere 3D model.
With them, you can apply an expression that moves all the facial muscles, or partial expressions that move only the upper or lower portions of the face.
You can apply a full face expression and then customize it applying the partials. This gives you more possibilities: change your idea on the go, leave the lips that you like and choose different eyes for the expression, use the parts of the expressions that you like more or even choose similar partials to subtly change the mouth or eyes in an animation, just like what happens in real life.
Natural expressions for real faces, with subtle asymmetries to enhance realism equates to good taste expressions with no grimaces.
Although they were made especially for The Girl 6, they also work on Genesis 2 Female(s) and figures based on her, such as Victoria 6.
