The Pack UVs dialog contains controls for clusters.
Inter face
(dro p-down)—Sets the packing method:
•
Linear Pack ing—Uses a linear method to lay
out t he faces. This method is fast but n ot very
efficient, and tends to lea ve 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 sp ace between
clusters.
The higher this setting, the larger t he gap that
appears between clusters.
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 mapping area. For best results, leave this
turned on.
Rot ate Clus ters —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 turned on, s maller clusters will
be placed in empty spaces within larger clusters to
take the most advantage of the available mapping
space.
OK —Accepts the 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 s ettings the
defaults for the cu rrent session.
Pelt Map Parameters Dialog
Unwrap UVW Modifier > Face sub-object le ve l > Map
Parameters rollout > Pelt > Edit Pelt Map
The primary function of the Pelt Map Parameters
dialog is to let you stretch out the UVW
coordinates into a flat, unified map that you
canthenusefortexturing. Whenthedialogis
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 functions available on the dialog
let you straighten out stretcher vertices, snap them
to the pelt seams, and so on.
