Edit UVWs Dialog 883
Unw rap UVW modifier and the Selection Modes
group. When you choose a sub-object level in one,
it’s also act ivated in the other. Similarly, selecting
sub-objects in a viewport s elects them in the e ditor
and vice-versa.
Expand S election—Adds sub-objects to the
selection.
Ver tex and face expansion proceeds outwards in
all available directions. Edge expansion proceeds
along available UV paths. For example, to select
a cluster outline, select one outer edge, and then
click Exp and S elect ion repeatedly.
Contra ct S e l e cti o n—Shrinks the selection by
deselecting the outermost sub-objects.
Pai nt S elect Mode—Lets you “paint” a
sub-object selection by drag ging in the editor
window. After activating this mode, move the
cursor into the editor window, and then drag to
select sub-objects. To exit Paint Select mode,
right-click or choose a transform tool.
P aint mode selects only sub-objects that are fully
insidetheselectionbrush. Thedottedcircle
attached to the mouse shows the size of the brush.
Use the +/- buttons next to the paintbrush button
to change its size.
+/-—Increases and decreases the size of the Paint
Select mode “brush”: the circle attached to the
mouse cursor.
Edge Loop—Expandsanexistingedgeselectionto
select all edges in the loop attached to the selected
edges. Select one or more edges, and then click
Edge Lo op.
Edge Loop uses a “center-path” method to
calculateloopselection. Tobeabletoexpand
a selection, there must be an odd number of
edges attached to either end of a selected edge
intheeditorwindow.Thesoftwarethenselects
the m iddle connected edge, a nd then continues

edge. Whenitencountersanedgeconnectedto
an even number of edges, or to which the middle
edge is already selected, it stops.
Sel ect El ement—Select ing a sub-object in a cluster
causes the entire cluster to become selected. Works
in al l sub-object modes.
Sync to Viewpor t—Causes any sub-object selection
in the viewports to be reflected in the editor
window.
Note: For this feature take effect, you must be at
the Select Face sub-object level of the Unwrap
UVW modifier. Also, for face and edge sub-object
selections to b e visible in a shaded v iewport, turn
on Shade Selected Faces (F2)and/orEdgedFaces
(F4).
Rot(ate) +90—Rotates the selection 90 degrees
about its center.
Rot(ate) -90—Rotates the selection -90 degrees
about its center.
Bitmap Op tions group
Click the Options Button to make this group
available.
Use Custom B itmap S ize—When turned on, scales
the bitmap texture to the values specified by Width
and Height. You can adjust these settings to scale
andreproportionthebitmaptextureinrelationto
the texture coordinates. This scaling doesn’t affect
the bitmap in the material, but only as viewed in
the editor.
Tip: When working with large textures, reduce
the bitmap size for faster feedback. And when
working w ith disproportionate textures, sett ing
the dimensions closer to each other in the editor
can m ake it easier to work.
Width—Scales the bitmap along the horizontal
axis.
