Right: Crease=0.0
Cr e as e—Specifies how much creasing is performed
on the selected edge or edges. At low sett ings, the
edge is relatively smooth. At hig her settings, the
crease becomes increasingly visible. At 1.0, the
highest setting , the edge is not smoothed at a ll.
Default=0.0. Range=0.0 to 1.0.

Force Q uad s—When on, the modifier converts all
non-quadrilateral faces or polygons to four-sided
polygons. When off, converts all polygons
to triang les. Available only when the object
contains any non-quadrilateral faces or polygons.
Default=off.
When you change the status of Force Quads, any
edits made in the HSDS modifier are lost. A
message appears warning you of this, and asking
you to confirm the change.
Because the modifier works best with four-sided
polygons, it’s recommended you confirm the
conversion if an object contains non-quadrilateral
facesorpolygons. Thesphereprimitiveisan
example of such an object; the uppermost and
lowermost faces are three-sided.

Material ID—Displays the material ID assigned to
the c urrent selection. Available only in Polygon
and Element sub-object modes. If multiple
sub-objects are selected and they don’t share an
ID, this field is blank.
You can change the material ID assigned to
selected sub-objects at the cur rent and higher
levels of detail by changing this setting.
Material IDs are used primarily with
Multi/Sub-Object material (p age 2–1403) .
Hide—Hides the current polygon selection.
Available only at the Polygon and Element
sub-object levels. Use Unhide All to reveal hidden
polygons.
Tip: Use Hide to i s olate part of an object you want
to work on. The Select Invert command on the
Edit menu is useful in this case. Select the faces

then click the Hide button.
Unhide All —Reveals hidden polygons.
Delete Polygon—Deletes the current polygon
selection, creating a hole or holes in the surface.
Available only in Polygon sub-object mode.

encompass the entire object surface, you cannot
delete polygons at the border of the control grid;
that is, polygons that do not share all edges with
other polygons in the grid.

best used for smoothing subdivided and edited
portions of the mesh when you’re finished using
the HSDS functionality.
Soft Se lection rollout
These controls let you set a gradual falloff of
influence between selected and unselected vertices.
