Normal M odifier
The Normal mo difier allows you to unify or flip
the normals of an object without applying an Edit
Mesh modifier .
For example, if you wanted to fly inside of a
procedural object, such as a sphere or a cylinder ,
and wanted to retain control over the radius and
number of segments, you couldn’t collapse the
object to an E ditable Mesh and m aintain the
procedural nature of the primitive.
Flipping the normals of a sphere creates a sky dome over
acity.
Tip: If you are animating the creation of a complex
object such as a nested Boolean or a loft, and you
think t he operation might result in inconsistent
faces, apply Normal to the result and turn on Unify.
Tip: The Lathe modifier sometimes creates an

Normal modifier w ith both Unif y and Flip turned
on to fix "inside-out" lathe objects. The Normal
modifier allows whole-object manipulations of
normals to be performed quickly w ithout using
an Edit Mesh modifier.

As of 3ds Max 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 the software will be
converted to meshes to m aintain backward
compatibility.
