The Smooth modifier provides
auto-smoothing based on the angle of adjacent faces. You can apply
new smoothing groups to objects.

At render time, faces in the same smoothing group appear as a smooth

As of 3ds Max Design 4, patch
objects coming up the modifier stack are not converted to a mesh
by this modifier. A patch object input to the Material modifier
retains its patch definition. Files that contain patch objects with
the Material modifier from previous versions of 3ds Max Design will
be converted to meshes to maintain backward compatibility.
- Auto Smooth
If Auto Smooth is selected,
the object is auto-smoothed using the (animatable) threshold specified
by the Threshold setting below it. Auto Smooth sets the smoothing
groups based on the angle between faces. Any two adjacent faces
are put in the same smoothing group if the angle between their normals
is less than the threshold angle.
- Prevent Indirect Smoothing

'leaks" when using Auto Smooth. If you apply Auto Smooth to an object,
and portions of that object that should not be smoothed become smoothed,
then turn on Prevent Indirect Smoothing to see if it corrects the

Smoothing Groups group
The grid of 32 buttons
shows which smoothing groups are used by the selected faces, and
are used to assign smoothing groups manually to selected faces.
