and the Weight setting are available for all
sub-objects at all levels. The Crease setting is
available only at t he E d ge sub-object level.
Cr e ase —Creates a discont inuity on a surface so
you get a hard edge, such as a wrinkle or lip. You

Crease setting; the crease appears in the surfaces
associated with the selected edges. Available only
attheEdgesub-objectlevel.
Weigh t—Sets the weig ht of selected vert ices or
edges. Increasing a vertex weight "pulls" the
smoothed result toward that vertex. Edge weights

manner in some respects. They aren’t really
"weights" as such, but "knot intervals," in NURBS
terminology. Consequently, increasing an edge
weight tends to push the smoothed result away.
Kinks will form in the result if weights of 0 are
used.
Isoline Display—When on, the software displays
only isolines: the object’s orig inal edges, b efore
smoothing. The benefit of using this option is
a less cluttered display. When off, the s of tware
displays all faces added by MeshSmooth; thus,

Show Cage—Toggles the display of a two-color
wireframe that shows the modified object before
subdivision. The cage colors are shown as

color represents unselected edges at the Vertex
sub-object level, and the second color represents
unselected edges at the E d ge sub-object level.
Change a color by clicking its swatch.
Soft Sele ction rollout
Soft Selection controls affect the action of
sub-object Mo ve, Rotate, and Scale functions.
When these are on, 3ds Max applies a spline curve
deformation to unselected vertices surrounding
the t ransformed selected sub-object. T his provides
a m agnet-like effect with a sphere of influence
around the transformation.
For more information, see Soft Selection Rollout
(page 1–963).

These settings are available only when
MeshSmooth Type is set to Classic or Quad
Output. Also, Project To Limit Surface is available
only in Classic mode.
Strength—Sets the s ize of the added faces u sing
arangefrom0.0to1.0.
• Va lues near 0.0 create small faces that are ver y
thin and close to the original vert ices and edges.
• Values near 0.5 size faces evenly between edges.
• Va lues near 1.0 create large new faces and make
the original faces very small.
Relax—Applies a positive relax effect to smooth
all vertices.
Project to Limit Sur face—Places a ll points on the
"limit sur face" of the MeshSmooth result, which
is the surface that would be produced after an
