Edge Dista nce—When on, limits the soft-selection
region to the specified number of edges between
where you select and the maximum extent of the
soft selection. The affected region is measured in
terms of "edge-distance" space, along the surface,
rather than real space.
This option is usef ul in cases where you want to
select only contiguous sections of geometry. For
example, if a bird’s wing is folded back against its
body, selecting the wing tip with Soft Selection
would affect body vert ices as well. But if you turn
on Edge Distance, set the numeric value to the
distance (in edges) along the wing that you wish to
affect, and then set Falloff to an appropriate value,
selectingandthenmovingthewingtipwould
move only the wing geometry.
A ffect Backfacing — When on, deselected faces
whosenormalsfaceintheoppositedirectionto
the ave rage normal of the selected sub-objects are
affected by the soft-selection influence. In the case
of vertices and edges, this applies to the normals
of faces to which they’re attached. Turn off Affect
Backfacing when you want to m anipulate faces of
athinobject,suchasathinbox,butdon’twantto
affect faces on the other side of the object.
Note: Affect Backfacing is not available when
editing splines.
Fa lloff—Distance in cur rent units from the center

slopes, depending on the scale of your geometry.
Default=20.
Note: The region specified by the Falloff setting
is depicted graphically in the viewports as a
color gradient in vertices and/or edges (or, with
editable polys and patches, optionally in faces).
The gradient ranges from the select ion color
(normally red) to the non-selected sub-object
color (normally blue). In addition, this gradient

Pinch—Raises and lowers the top point of the
curve along the vertical axis. Sets the relative
"pointedness" of the region. When negative, a
crater is produced instead of a point. At a setting
of 0, Pinch produces a smooth transition across
this axis. Default=0.
Bu bble—Expands and contracts the curve a long
the vert ica l axis. Sets the relative "fullness" of
the region. Limited by Pinch, which sets a fixed
starting point for Bubble. A setting of 0 for Pinch
and 1.0 for Bubble produces the smoothest bulge.

Soft Selection will work. You can experiment with
a cur ve setting, undo it, and try another setting
w ith the same selection.
Sha ded Face Toggle—Displays a color gradient
corresponding to the soft selection weights on
faces within the soft selection range. Available
only when editing p atch and poly objects.
If the
Vertex Color display property
of an editable
poly or editable patch object is off, clicking the
ShadedFaceTogglebuttonwillturnonSoft

an active Vertex Color setting, pressing the Shaded
FaceTogglewilloverridetheprevioussettingand
change it to Soft Selection Color.
Note: Use the Undo command if you do not want
to change yo ur vertex color shading properties.
