instabilities. A good value is 0.01 (note: the default
is 0.1, but in practice, it seems that this value is
too high).
Air Res.— Resistance to Air. This value w i l l
determine how much the air will effect the cloth. A
higher amount of air resistance would be useful for
a tightly woven fabric, while a lower amount would
be suitable for a loose-knit garment.
Dyn. Fric.— Dynamic f riction between the cloth
and solid objects. A larger va lue w i ll add more
fric tion and cause the fabric to slide less across
an object. A lower v alue will allow the fabric to
slip off an object very easily, similarly to how si lk
would react.
Static Fric. — Static friction between the cloth and
solid objects. When t he cloth is in st ationary
position, this value will cont rol its ability stay
where it is, or slip away.
Self Fric.— Friction between the cloth and itself.
This is similar to dynamic and static friction, but
applies to cloth-to-cloth or self-collisions. A larger
value will cause more friction between the cloth
and itself.
UScale—Controls how much to shr ink or expand
the cloth along the U direction (as defined by
Garment Maker. For non-Garment Maker meshes,
this applies a uniform sc aling to the cloth along
both axes, and the V Scale par ameter is ignored).
Avalueoflessthan1willshrinkthefabricat
simulation time, while a value of more than 1 will
stretch it.
VScale—Controls how much to shrink or exp and
the cloth along the V direction (as defined by
Garment Maker). A va lue of less than 1 will shrin k
thefabricatsimulationtime,whileavalueofmore
than 1 will stretch it.
Seam Force—Notpresentlyusedandonlykeptfor
backward compatibility with older versions of the
former product called Stitch. This was a global
seam st rength, but seam strength is now defined
on a seam-by-seam basis at the Seams sub-object
level.
Plasticity—The tendency of the cloth to keep its
current deformation (that is, the bend angles).
This is different from
Keep Shape
,which
determines the extent to which the cloth tends to
keep its original deformation (or the one defined
by the Target State). If you set Plast icity to 100.0,
the cloth will not attempt to change the angles
between triangles. If you want stiffer cloth, but you
don’twanttheclothto"balloon"up,increasethe
Plasticity value.
Depth—Collision depth. If a portion of cloth
reaches this depth inside a collision object, then
the simulation will no longer try to push the cloth
out of the mesh. This value is measured in 3ds Max
units.
Offset—The amount of distance kept between the
cloth and the collision object. A very low value
can cause t he collision mesh to protrude out from
under the cloth. A ver y high value will cause
thefabrictolookasifitisfloatingontopofthe
collision object.
Use Cloth Dep th/Offs et—Uses the Dept h an d Offset
values set for the panel (see preceding). When on,
the cloth object ignores the collision object D epth
and Offset values.
Based on—Lists the preset that the panel properties
are based on. When you modify parameters and
save a preset, Cloth u ses the name of the last preset
you loaded as the “Based on” name.
Anisotropic—When on, you can set different U
andVvaluesfortheBend,B-Curve,andStretch
parameters. T he U and V directions are defined
by
Garment Maker (page 1–587)
and do not apply
to non-Garment Maker meshes, for which setting
different U/V va lues might result in unexpected
behav ior.
