Puppet Overlap controls
When you are distorting one part
of an image, you may want to control which parts of the image appear
in front of other parts. For example, you may want to keep an arm
in front of the face as you make the arm wave. Use the Puppet Overlap
tool to apply Overlap pins to the parts of an object for which you
want to control apparent depth.
You apply Puppet Overlap pins
to the original outline, not to the deformed image.
 Overlap pin with negative In Front value (top), and Overlap
pin with positive In Front value (bottom) Each
Overlap pin has the following properties:
- In Front
- The apparent proximity to the viewer. The influence of Overlap
pins is cumulative, meaning that the In Front values are added together
for places on the mesh where extents overlap. You can use negative
In Front values to cancel out the influence of another Overlap pin
at a specific location.
An area of the mesh that is not influenced
by Overlap pins has an implicit In Front value of 0. The default
value for a new Overlap pin is 50.
 When animating
the In Front value, you should usually use Hold keyframes. You do
not usually want to interpolate gradually from an element being
in front to an element being in back. - Extent
- How far from the Overlap pin its influence extends. The influence
ends abruptly; it does not decrease gradually with distance from
the pin. Extent is indicated visually by a fill in the affected
parts of the mesh. The fill is dark if In Front is negative; the
fill is light if In Front is positive.
