isolating dynamic effects.

settings to interpolate
or animate between the sets. The Use Cloth
Depth/Offset, Use Edge Springs, Use Solid
Friction, and Keep Shape options can be set only
for Property 1 because Property 2 uses the same
settings.
Clo th—Sets the object or objects highlighted in
the Objects In Simulation list to cloth objects and
allows you to define parameters for them in the
Cloth Properties section of the dialog.
Use Pa nel Properties—When on, tells Cloth
to use the Cloth Properties from the Panel
sub-object level of the Cloth modifier. This allows
you to define different cloth properties on a
panel-by-panel basis.

Preset s—Sets the Cloth Properties parameters to
the preset chosen from the drop-down list. Any
presets that are built into t he system or that have
been previously saved and loaded will show up
here.
Loa d—Loads presets from your hard drive. Click
this button and then n avigate to the directory with
your presets to load them into Cloth Properties.
Save—Sav es Cloth Properties parameters to a file
to be loaded at a later time. By default, all Cloth
preset fi les are saved to your
\scenes\cloth
folder .

bend. A cotton fabric might bend more easily than
leather, so a value of 15.0 for both U and V Bend
might be good for cotton, while 50.0 would work
well for leather.
By default, the U Bend and V Bend parameters
are locked together so that changing one sets the
other to the same value. You c an set different
values for the two only when

Thickness— Defines the virtual thickness of a
fabric for the purp ose of detecting cloth-to-cloth
collisions. This value is irrelevant if cloth-to-cloth
collisions are disabled. Larger values keep the
cloth separated by greater distances. Be careful
not to use too large or small values in this field.
Very large values wil l interfere with the natural
behavior of the cloth. Very small values will cause
the simulator to take too long to calculate. This
distance is measured in cm (centimeters) and
should be smaller than the size of the triangles that
make up the cloth object. A setting of 0.0 w ill let
Cloth automatically assign a reasonable value for
thickness.
