together and the mesh contains many different
areas to map.
Affect Center T ile—When turned on, the Brightness
setting affects all tiles equally. When off, the center,
or “home,” tile always remains at full brightness,
so you can easily distinguish t he home tile from
the copies.
Co nstant Update in Viewports—Affects the
adjusting of UVW vertices in the viewport while
youmovethemouse.Default=off(theeffectof
adjustingtheUVWverticesdoesnotappearinthe
viewport until you release the mouse).
Show Image Alpha—Displays the alpha channel
of the background i mage in the editor, if it exists.
Show Hidden Edges—To g g l e s t h e d i s pl ay o f f a ce
edges. When turned off, only faces appear. When
turned on, all mesh geometry appears.
Blend Tile to Background—Affects the color to
which tiles set to Brightness less than 1.0 blend.
When turned off, tiles blend to black. When
turned on, tiles blend to the
background color
.
Misc. Preferences
Center P ix el S nap—When turned on, snaps to the
center of pixels of the background images instead
of pixel edges.
Gri d S nap—When on, snaps to gr id edges and
intersections.
Vertex Snap—When on, snaps to
texture-coordinate vertices.
Edge Snap—When on, snaps to
texture-coordinate edges.
Weld Thr es hold —Sets the radius within which
welding using
Weld Selected
takes effect. The
setting is in UV-space distance. Default=0.01.
Range=0 to 10.
Grid Size—Sets the spacing of hori zontal and
vert ical grid lines. Default=0.1.
Setting Grid Size to 0 effectively turns off the gr id.
At the highest value, 1.0, the gr id is the same size
as the texture.
Snap Str(ength)—Sets the
grid snap
strength.
Default=0.2. Range=0 to 0.5.
Setting the strength to 0 effectively turns off
snapping. At values less than 0.3, grid snapping
tendstogotogridedges.Atthehighestvalue,0.5,
grid snapping goes only to grid intersections.
Selection Preferences
Soft Selection Edge Distance—When
Soft Selection
(page 1–882)
is turned on, limits the falloff region
by the specified number of edges between the
selection and the affected vert ices. The affected
region is measured in terms of "edge-distance"
space rather than absolute distance. Default=16.
Single Click Hit Size—Sets how far away you can
click from a sub-object to select it. Default=4.
Range=1 to 10.
Selected Tick Size—Setsthesizeofthesquare
icon the editor window uses to indicate selected
vertices.Default=2.Range=1to10.
OK /Cancel/D ef au lt s—Click OK to accept, or Cancel
to cancel the changes in the dialog. Click Defaults
to restore all settings in this dialog to default values.
