2-Si ded ( Double S ided)
Rendering of a box w ith a double-sided material, a nd same
box with a single-sided material
In 3ds Max, faces are one-sided. The front is the
side w ith the surface
normal (page 3–1074) .The
backsideofthefaceisinvisibletotheRenderer;
meaning the face appears to be missing when
viewed from the back. Objects are usually created
w ith the sur face nor m als 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 AutoCAD) in which the face
normals are not properly unified, you can use
one of the methods above to render each face
regardless of its normal’s orientation. You can
also unify normals explicitly by using the
Normal
modifier (page 1–738)
.
2D Map
A two-dimensional image or pattern. A 2D map
requ ires mapping coordinates to render and
appear in viewports. See
2D Maps (page 2–1434) .
