4 Rename the duplicate face as smilingFace.
This duplicate face will be modified so it can be used to influence the
original.
Creating a cluster deformer on a target object
In the next steps, you create a cluster deformer on the duplicated face (target
object) to reshape the expression into a smile. The cluster deformer on the
target object will be used to change the unsmiling baseFace (base object) into
a smiling face.
A cluster deformer creates a set whose members consist of selected points (CVs,
vertices, or lattice points). You assign a percentage weight to each point,
indicating how much you want each point to be affected by any translation,
rotation, or scale of the cluster set. When you transform the cluster, the points
are transformed according to the percentages you have specified. A cluster is
useful for stretching, moving, or compressing part or all of a surface.
To create a cluster deformer
1 Position the mouse pointer over the face. Right-click to select Vertex,
then select the smilingFace vertices shown in the following illustration,
which are roughly the vertices at the chin, cheeks, and lips (but not the
nose):
