Soft S ele ction rollout
Soft Selection controls affect the action of
sub-object Move, Rotate, and Scale functions.
When these are on, 3ds Max applies a spline curve
deformation to unselected vertices surrounding
the transformed selected sub-object. This provides
a magnet-like effect with a sphere of influence
around the transformation.

MeshSmooth Type is set to Classic or Quad
Output. Also, Project To Limit Surface is available
only in Classic mo de.
Strength—Setsthesizeoftheaddedfacesusing
arangefrom0.0to1.0.
• Values near 0.0 create small faces that are very
thin and close to the original vertices and edges.
• Values near 0.5 size faces evenly between edges.
• Values near 1.0 create large new faces and make
the original faces ver y small.
Relax—Applies a positive relax effect to smooth
all vertices.
Project to Limit Sur f ace—Places all points on the
"limit surface" of the MeshSmooth result, which
is the surface that would be produced after an
infinite number of iterations. The topology is still
controlled by the number of iterations.
Parameters rollout > Surface Parameters gro up
Ap plies smoothing groups to the object and
restrict the MeshSmooth effect by surface
properties.
Smooth R es ult—Applies the same smoothing
group to all faces.
Separ ate by M ateria ls—Prevents the creation of
new faces for edges between faces that do not share
Material IDs.
Sepa rat e by S moothing Gr oups—Prevents the
creat ion of new faces at edges between faces that
don’t share at least one smoothing group.
