A value of 0.0 is a special case: When the
Change value is 0.0, no tiles appears in that row,
and the underlying material shows through.

tile height. Values greater than 1.0 increase the
height of tiles, and values less than 1.0 decrease

3D
3D maps are patterns generated procedural ly in
three dimensions. For example, Marble has a g rain
that goes through the assigned geometry. If you

as its texture, the grain in the cutaway p or tion
matches the grain on the object’s exterior. T he
following3Dmapsareavailablein3dsMax:
Cellular (page 2–1664): Generates a cellular
pattern that’s useful for a v ariety of visual effec ts,
including mosaic tiling, pebbled surfaces, and
ocean surfaces.
Dent (page 2–1667): Generates three-dimensional
bumps over a surface.
Falloff (page 2–1670): Generates a v alue from
white to black based on the angular falloff of
thefacenormalsonthesurfaceofthegeometry.
The Falloff map provides greater flexibility when
creating opacity falloff effects. Other effects
include Shadow/Light, Distance Blend, and
Fresnel.
Marble (page 2–1673): Simulates the grain of
marble with two explicit colors and a third
intermediate color.
Noise (page 2–1674):Noiseisaturbulencepattern
in three dimensions. Like Checker in 2D, it is based
on two colors, either of which can be mapped.
Particle Age (page 2–1675):Altersthecolor(or
map) of a particle based on the particle’s life.
Particle MBlur (page 2–1676):(MBlurisshortfor
Motion Blur.) Alters the opacity of the leading
and trailing ends of par ticles based on their rate
of movement.
Perlin Marble (page 2–1677):Analternative,
procedural marble map with a turbulence pattern.
Planet (page 2–1678): Simulates the contours of a
planet as seen from space.
Smoke (page 2–1679): Generates fractal-based
turbulence patterns to simulate the effects of
smoke in a beam of light, or other cloudy, flowing
mapping effects.
Speckle (page 2–1680): G enerates a speckled
surface for creating patterned surfaces that can
simulate granite and similar materials.
Splat (page 2–1681): Generates a f r ac t a l pattern
similar to splattered paint.
