Combine this w ith Center Pixel Snap to snap to the
center of pixels rather than the corner.
Note: With multiple vertices selected, all vertices
snap to the near est pix el, relatively; this can slightly
alter the spatial relationships among them.
Options panel
By default, the Options panel, docked to the
bottom of the Edit UVWs dialog, provides
cont rols for using soft select ion, specifying
selection modes, and rotating the selection. The
Options button lets you toggle the display of
additional settings for bitmaps, viewports, and
the editor.
Soft Selection group
The Soft Selection controls mak e a sub-object
selection behave as if surrounded by a "magnetic
field." Unselected sub-objects within the field
are drawn along smoothly while you transform
the sub-object select ion, the effect dim inishing
with distance. You can adjust this distance, or
“falloff,” whether it applies to object space, texture
space, or edge space, and the formula by which it
diminishes.
First, set a va lue that encompasses sub-objects
to be moved or scaled, and then transform
sub-objects w ith a falloff effect.
On—Ac t ivates or deactivates soft selection.
XY/UV —Specifies object or texture space for the
falloff distance. XY selects object space, UV selects
texture space.
Fa lloff—Sets the falloff distance. As values increase,
unselected vertex colors change gradually from the
selected vertex to reflect the area of influence.
Edge Distance—Turn on to limit 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"
spaceratherthanabsolutedistance.
Fa lloff Type—Transforming with soft selection
affects non-selected vert ices within the falloff area
based on the falloff type.
The icons depict how t heir buttons affect falloff.
The options are:
•
Smooth
•
Linear
•

Note: Selected sub-objects are colored red by
default. Also, in Edge and Face sub-object modes,
any shared edges are blue by default. A shared
edge is one both of whose endpoints are shared
by a selected edge or face; thus, it is, in effect,
also selected. You can change these colors using
Customize User Int erface > Colors panel (page
3–799).
The three sub-object levels are synchronized
