Mirror Offset—Movesthemirrorplaneaswellasall
mirrored vert ices.
Mi r ror Thr eshold—Sets the distance, in system
units, that Skin Wrap uses to find a control vertex
near a projected vertex. Increase this if vertex
locations are not the same on either side of the
mirror plane.
Mirror Selected—Copies the local settings from
each selected control vertex to any control vertices
w ithin the threshold distance of its projected
location on the other side of the mirror plane.
BakeControl Ver ts—Stores the Local Strength/Scale
and the global Falloff, Distance Infl., and Face
Limit settings on the control objects for later
retrieval with Retrieve Control Vertices.
Note: This data is static; any changes to the
base-object topology invalidates it.
Retr ieve Control Ver ts—Take s a ny cont rol -ve r t ex
data stored on the control objects with Bake
Cont rol Ver tices and copies them into the mo difier.
Display Parameters rollout
These settings determine whether 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 Ax is—Displays the a xis tripods for selected
control vertices. Default=on.
Display Face Limit—Shows all base-object points
that the selected control vertex or vertices can
affect. Thisisavisualizationofthe

.Default=on.
Display Unass igned Points —Draws a red circle
around each base-object point that the system
did not find a closest face for and dr aws a red box
around each point that has a closest face but is not
weighted by any control vertex. Default=off.
Unassigned points: The circled p oints (bottom) have no
closest face, while the points with red boxes (center) have a
closest face but aren’t weighted by control vertices.
This is an important debugging tool because any
vertex that is not assigned a closest face will never
be weig hted. 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 b e fixed by increasing t he Local
Scale of a control vertex near that point.
Display Control V er ts—Toggles display of all control
ver t ices. Default=on.
