Cloth Modifier 589
The numeric sett ing specifies the extent to which
Cloth tends to avoid self-colliding cloth objects,
at the cost of simulation time. Range=0 to 10.
Default=1.
This is a maximum limit. If Cloth needs fewer
calculations to resolve all collisions, it will use
fewer. In most cases, a va lue g reater than 1 isn’t
necessary.
Solid Collision—When on, the simulator takes into
account cloth-to-solid object collisions. This is
almost always left on.
Use S ewing Springs—When on, uses the sewing
springs created with Garment Maker to pull the
fabric together.
This works only w ith objects that have been
made w ith Garment Maker (page 1–607).Turn
this option off once the garment has been pulled
together. When off, Cloth will identify vertices
that are sewn together and will always keep them
coincident. When on, there is always a chance for
the vertices to come apart if the sewing springs are
not strong enough (actually, there will always be
some slight gap bet ween the vertices in this case).
Show Sewing Springs—Toggles the visual
representat ion of the sewing springs in the
viewports. These do not render.
Sim on Render—When on, triggers the simulation
at render time. Use this for generating a simulation
w ith a network computer, which lets you continue
to work on other aspects of your scene with your
own computer. See a procedure here (page 1–581).
After the render is completed, Cloth writes a cache
for each cloth object. You can specify this cache file
on the Selected Object rollout (page 1–585) (which
is available only when a single object is selected).
If you do not specify a name, the software creates
one.
The numeric value indicates the priorit y of the
simulation; the simulations are run in ascending
order. For modifiers with the same priority, the
order is undefined.
Note: E ach object has its own cache file, w hich is
temp orar i ly created when the MAX file is opened.
On saving the file, the cache is incorporated into
the MAX fi le. When Sim On Render is on, the
cache file specified is created and written to, but is
not read from as you change the time slider. The
cachefilemustbeloaded into the internal cache
file before you can see it.
Advanced P inching—When on, Cloth tests for cloth
pinched between two parts of the same collision
object.
This option helps with cloth colliding with
small features of the collision objects, such as
fingers. There is a significant performance hit for
high-resolution collision objects.
Tens ion—Lets you visualize the compression/
tensioninthefabricbymeansofvertexcoloring.
Stretched cloth is indicated by red, compressed
by blue, neutral by green. The numeric setting
lets you change the range of tension/compression
illustrated by a complete traversal from red to
blue. The higher this value, the more gradual the
shading. This works only for Garment Maker
objects.
Group rollout
The Group sub-object rollout is for selecting
groups of vertices and constraining them to
surfaces, collision objects, or other cloth objects.
At the Group sub-object level, al l selected objects
that are part of the Cloth simulation are shown
with their vertices v isible s o that you can select
them in an efficient fashion.
When you create or select a group at this sub-object
level, the Group Parameters rollout becomes
available.
Impor tant: The concept of a group for Cloth can be
applied to both t he cloth objects and to the collision
