Faceted
Vase on the right us es a faceted material.
Faceted shading provides a constant shading
across each facet, or co-planar surface of the
object. The result has the appearance of so-called
"flat" shading, except that it provides specular
high lights.
Turn on Faceted to provide a faceted look to your
geometry without having to explicitly change the
smoothing g roups in the object w ith the Edit Mesh
modifier.
Both Standard (page 2–1465) and Raytrace (page
2–1512) materials provide a Faceted toggle.
Note: This feature was known as “constant
shading” in versions of 3ds Max prior to v5.
FFD
FFD stands for free-form deformation.Itisusedin
computer animation for effects like dancing cars
and gas tanks. You can use it as well for mo deling
rounded shapes such as chairs and sculpture.
An FFD modifier (page 1–683) surrounds the
selected geometry with a lattice box or cylinder.
By adjusting the control points of the lattice, you
deform the enclosed geometry.
Note: Yo u c a n u s e Physique (page 2–1076) to
control an FFD space warp. Physique actually
deforms the space warp’s control poin ts, which in
turn deform the model.
FGM File
An FGM file (.fgm) is a final gather map file. It is
used by the mental ray renderer (page 3–78) to save
the results of a final gathering p ass. Generating
and saving an FGM fi le can speed up subsequent
renderings.

Above: Narrow field of view
Below: Wide field of view
Field of View defines the width of your view as an
angle with its apex at your viewpoint and the ends
at the sides of the v iew. The effect of changing FOV
is s im ilar to chang ing the lens on a c amera. As the
FOV gets larger you see more of your scene and
the perspective becomes distorted, simi lar to using
awide-anglelens. AstheFOVgetssmalleryou
see less of your scene and the perspective flattens,
similar to using a telephoto lens.
A Perspective view uses an imaginary camer a
with only one setting, FOV. The FOV angle
for the active Perspective view is displayed in
the Rendering Methods panel of the Viewport
