810 Chapter 8: Modifiers
Procedure
To use Skin Wrap (basic method):
1.
Create a high-resolution base object and one or
more low-resolution control objects, which will
deform the base object. In general, each control
object should have an overall s hape similar to
the part of the base object that it will deform,
and be positioned near that par t of the base
object.
2. Apply Skin Wrap to the high-resolution base
object. The modifier transfers animation or
modeling from the control object to the base
object.
3. On the Skin Wrap > Parameters rollout, use
Add to assign the control object(s).
4. Choose a deformation engine: Vertex or Face.
5. Set global parameters as desired. These
parameters affect all control vertices, and
include Deformation Engine, Falloff, Distance
Influence, and Face Limit.
6. To set local parameters, including strength and
influence distances, access the Control Vertices
sub-object level of the Skin Wrap. Select one
or more control vertices, and then change the
settings as necessary.
7. Edit or animate the control object with
modifiers and/or sub-object transforms;
the hig h-resolution (base) object deforms
accordingly.
8. Repeat steps 5, 6, and 7 as necessary.
Occasionally you might need to reset the
modifier as well, by clicking the Reset
button. Before doing so, always return to a
non-deformed point (or “skin pose”) in the
animation; typically, frame 0.

Control V ert ices sub-object level At the Control
Ver tices sub-object level, you can view and select
vertices on the control object(s), and set
local
parameters (page 1–812)
for any selected vertices.
By default, each selected vertex is sur rounded
by
loops
that depict its volume of influence.
This sub-object level also uses color coding on
affected points in the base object to show each
selected vertex’s relative effect on p oints within
the volume of influence. Colors range from orange
for the strongest influence to blue for the weakest
influence. Red is for vertices that are within its
range of influence but that it’s not influencing.
By default, at this level, control vertices appear
as small orange squares. To prevent this, turn
off Display Parameters rollout > Display Control
