triangles, rather than joining together more than
two tr iangles into pentagons, hexagons, and so on.
Max Size—The maximum number of sides to a
polygon.
Require P lanar Polygons—Cr eates polygons
comp osed of flat planes. Does not join faces
togetheracrossanedgeiftheedgehasasharper
angle than the threshold listed.
Threshold—Controls the threshold of the angle
between polygonal planes.
Remove Mid-Edge Vertices—Eliminates divisions
that result from intersections with invisible edges.
Sub-object Selections group
These options control the selection of sub-objects.
Preserv e—Passes the sub-object selection up the
stack. For example, if you have an object that you
have converted to an editable mesh, and you’ve
selected a polygon, then when you apply a Turn
To Poly modifier, the polygon remains selected.
Default=on.
Cle ar —Clears the sub-object selection so that
nothing is selected. Default=off.
Inver t—Inverts the sub-object selection. All
sub-objects not currently selected are selected, and
all sub-objects currently selected are deselected.
Default=off.
Include S of t S electi on—Affects 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 magnet-like effect, with a sphere of influence
around the transformation. Use this when you
want to preserve the soft selection from beneath.
Forexample,ifUseSoftSelectionisonwhenyou
select vertices on an editable mesh, and you apply
Turn To Poly with Include Soft Selection on, then

ver t ices. Default=on.
For more information, see Soft Selection Rollout
(page 1–963).
Selection Level group
These options set t he sub-object selection level for
passing up t he rest of the stack.
From Pipeline—Uses the equivalent of whatever
the input object uses (patch level becomes face
level, and so on). For example, if you create a box,
convertittoaneditablemeshinfacemode,and
apply a Turn To Poly modifier to it, 3 ds Max passes
a sub-objec t selection in face mode up the stack.
The Turn To Poly mo difier ta kes the sub-object
face selection into account and selects the polygons
that derive from the face selection.
Object—Uses object as the selection level for
passing up t he rest of the stack.
Edge—Uses edge as the sub-object selection level
for passing up the rest of the st ack.
Vertex—Uses vertex as the sub-object select ion
level for passing up the rest of the st ack.
Face—Uses face as the sub-object selection level
for passing up the rest of the st ack.

The Twist modifier produces a twirling effect (like
wringingoutawetrag)inanobject’sgeometry.
You can control the ang le of the twist on a ny of
three axes, and set a bias that compresses the twist
effect relative to the pivot point. You can also limit
the twist to a section of the geometry.
