These settings determine w hether or not the
software displays different elements in the Skin
Wrap modifier.
Display Loops—Displays volumes of influence for
selected control vertices as red loops. Default=on.
Display A xis —Displays t he axis t ripods for selected
control vertices. Default=on.
Display Face Limit—Shows all base-object points
that the selected control vertex or vertices can
affect. This is a visualization of the Face Limit
setting.Default=on.
Display Unassigned Points—Draws a red circle
around each base-object point that the system
did not find a closest face for and draws a red b ox
around each point that has a closest face but is not
weighted by any control vertex. Default=off.
Unassigned points: Th e circled points (bottom) have no closest
face, while the points w ith red boxes (center) have a closest
face but aren’t weighted by control vertices.
This is an import ant debugging tool because any
vertex that is not assigned a closest face will never
be weighted. To do so, you need to increase the
Threshold value and click Reset, or turn on Weight
All Points. Any points that are not weighted to a
control vertex can be fixed by increasing the Local
Scale of a control vertex near that point.
Display Control V er ts—Toggles display of all control
vertices. Default=on.

Skin Wrap Patch is a simple modifier that allo ws
apatchobjecttodeformameshobject. It’svery
easy to use: just assign the modifier to a mesh
object, and then use the modifier to specify a
deforming patch object. Each point on the patch
object influences a su rrounding volume of points
on the mesh object.

Pick Patch—Click this button, labeled “None” by
default, and then select a patch object to deform
the mesh object. After picking the patch object, its
name appears on the button.
Sample Rate—Determines the accuracy with which
the modifier samples the patch object. The higher
therate,themoreaccuratetheresultinganimation
will be, but the longer it w ill take to calculate.
Resample—Forces the system to resample the date.
This should be done at a point in the animation at
which no deformation takes place; typically, frame
0.
