Cloth Modifier 567
Bend Map group
The Bend Map option lets you use a texture map,
map channel, or vertex colors to modulate the
target bend angles. The value of this is that you c a n
paint deformations onto your cloth, or use some
kind of noise map to add irregularity to the cloth.
Bend Map—Toggles the use of the Bend Map
option.
Set the st rength of the modulation with the
numeric value. In most cases, the value should be
less than 1.0. Range=0.0 to 100.0. Default=0.5.
[map ty pe]—Choose the map ty pe for the Bend
map:
•
Vertex Color—Uses the Vertex Color channel for
modulation.
•
Ma p Channel—Uses a map channel other than
Vertex Color for modulation. Set the channel
w ith the spinner.
•
Texture Map—Uses a texture map for
modulation. To specify a texture map, click
thebutton(labeledNonebydefault)andthen
use the Material/Map Browser to choose the
map. Thereafter the map name appears on the
button.
Simulation Parameters rollout
The Simulation Parameters rollout settings let you
specify general properties of the simulation such as
gravity, start and end frames, and sewing-spring
options. These settings apply to the simulation
onaglobalscale,thatis,toallobjectsinthe
simulation.
cm/unit—Determines how many centimeters there
are per 3ds Max unit. Size and scale are important
when doing cloth simulation because a 10-foot
curtain behaves much differently from a one-foot
square handkerchief, even if they are made of the
same fabric. The default is set to 2.54 centimeters
for each 3ds Max unit. This makes each 3ds Max
unit equal to about an inch. You may set this to
1 which will make each 3ds Max unit equal to a
cent imeter, or 30 which will equal a foot for each
3ds Max unit.
Ear th—Click this button to set the Grav ity value
to that of planet Earth.
Grav ity —When on, the Gravity value (see
following) affects cloth objects in the simulation.
[Gr av it y va lu e]—The force of gravity in cm/sec
2
.
A negative value applies g ravitational force
downward. A positive value (i.e., no sign) means
grav ity w ill act to move cloth objects upward.
