Pack UVs Dialog 909
Rot ate Cluster s—
Controls w hether clusters are
rotated to m inimize the size of their bounding
box. For instance, the bounding box of a rectangle
rotated 45 degrees occupies more area than one
rotated 90 degrees.
Align B y W idth—Controlswhetherthewidthorthe
height of the clusters is used to control the layout
of the clusters.
OK —Accepts the sett ings, closes the dialog, and
performs the mapping as specified.
Cancel—Undoes any changes and closes the dialog.
Set As Default—Makesthecurrentsettingsthe

Pack UV s Dialog

Object-Space Modifiers > Unwrap UVW > Edit button (on
Parameters rollout) > Tools menu > Pack UVs
The Pack UVs dialog contains controls for clusters.
Inter face
(dro p-down)—Sets the p acking metho d :
•
Linear Pack ing—Uses a linear method to lay
out the faces. This method is fast but not very
efficient, and tends to leave a lot of unused UV
space.
•
Recursive Pack ing—Slower than the Linear
method, but packs the faces more efficiently.
Spacing —Controls the amount of space between
clusters.
The higher this setting, the larger the gap that
appears between cl usters.
Normalize Clusters— Controls whether the final
layout will be scaled down to 1.0 unit to fit within
the standard editor mapping area. If this is turned
off,thefinalsizeoftheclusterswillbeinobject
space, and they’ll probably be much larger than
the editor m apping area. For best results, leave this
turned on.
Rot ate Cluster s—Controls whether clusters are
rotated to minimize the size of their bounding
box. For instance, the bounding box of a rectangle
rotated 45 degrees occupies more area than one
rotated 90 degrees.
Fill Holes—When tur ned on, smaller clusters will
be placed in empty spaces within larger clusters to
take the most advantage of the available mapping
space.
OK —Accepts t he settings, closes the dialog, and
performs the packing as specified.
Cance l—Undoes any changes and closes the dialog .
Set As Default—Makes the current settings the
defaults for the current session.
Pelt Map Parameters Dialog
Unwrap UVW Modifier > Face sub-object level > Map
Parameters rollout > Pelt > Edit Pelt Map
The primary function of the P elt Map Parameters
dialog is to let you stretch out the UVW
coordinates into a flat, unified map t hat you can
then use for texturing. When the d ialog is open,
the stretcher appears in the Edit UVWs dialog
window as a circle of points, each of which is
attached to a vertex on a pelt seam. You can
manipulate these vertices exactly as any other
ver tex in the editor, selecting, rotating, moving ,
etc. Other special funct ions available on the dialog
