2-Si ded (Double S ided)
Renderin g of a box with a double-sided material, and same
box with a single-sided material
In 3ds Max, faces are one-sided. The front is the
side with the surface norm al (page 3–980).The
backsideofthefaceisinvisibletotheRenderer;
meaning the face appears to be missing when
viewed from the back. Objects are usually created
w ith the surface normals facing outward, but it is
possible to create objects with the faces flipped
or to import complex geometry in which the face
normals are not properly unified.

Either turn on the Force Two Sided option in the
Render dialog, or apply a two-sided material to
the geometry.
Usually, you want two sided rendering turned off
since it slows rendering time. However, if you
wanttorendertheinsideaswellastheoutsideof
objects, or if you’ve imported complex geometry
(for example, from A utoCAD) in which the face
normals are not properly unified, you can use
one of the metho ds above to render each face
regardless of its normal’s orientation. You can
also unify normals explicitly by using the Normal
modifier (page 1–746).
2D Map
A two-dimensional image or p attern. A 2D map
requ ires mapping coordinates to render and
appear in view ports. See 2D Maps (page 2–1624).
3D DWF
From Design Web Format. A highly compressed
file format that is created from a MAX file. DWF
files are easy to publish and view on the Web using
the Autodesk DWF Viewer.
