Cloth Modifier 593
Radius—
When on, lets you set the radial distance
used by the Blob option (see preceding). When
off, Blob uses an automatic radial value.
Behavior Settings group
Behavior Settings—Toggles the availability of the
other settings in this group. When off, the other
settings have no effect.
Solid Coll—When on, the group vertices are used
in solid-collision detection.
Self Coll—When on, the group vertices are used in
self-collision detection.
Layer—Indicates the correct "order" of cloth
pieces that mig ht come in contac t with each other.
Range=-100 to 100. Default=1.
If your garments and/or panels are all correctly
orientated to begin with, then cloth-to-cloth
collision detection should keep items from
interpenetrating. However, the initial state of a
garment/panel might have some interpenetration
that cannot be resolved. For example, suppose you
make a jacket with Garment Maker where the front
rightpanelissupposedtositontopofthefront
left panel. When you sew together the garment
(generally with self-collision off), the front panels
will interpenetrate, so to make sure that the right
panelsitsoutsidetheleftpanel,youmighthave
to use constraints or Live Drag. Using the L ayers
option on the panels can help here.
Here is the logic of layers: When two pieces of
cloth (A and B) are in collision-detection range,
their layers (layerA and layerB) are compared and
the following rules are applied:
• If either layerA or LayerB is 0, then Cloth uses
the regular cloth-to-cloth collision method.
• If l ayerA=layerB, then Cloth uses the regular
cloth-to-cloth collision method.
• If abs(layerA) > abs(layerB) then piece A is
pushedtotheappropriatesideofpieceB.
Which side? If layerB > 0, then to the side
indicated by the face normals. If layerB<0 then
to the opposite side.
The sign of the Layer va lue indicates what the
"outside" of that piece of cloth is. A positive sign
means "The side that the normals face is the
outside".
Keep Shape—When on, preserves the shape of the
mesh based on the Bend % and Stretch % settings
(see following). In normal operation, when Cloth
creates a simulation, it tries to "flatten out" the
cloth.
Bend %—Modulates the target bend angles to a
value between 0.0 and the angles defined by the
target state. A negative value inverts the a ngles.
Range=-100.0 to 100.0. Default=100.0.
Stretch % —Modulates the target stretch angles to
a value between 0.0 and the angles defined by the
target state. A negative value inverts the a ngles.
Range=-100.0 to 100.0. Default=100.0.
Presets group
Sets the C loth Properties parameters to the preset
selected in the drop-dow n list. Any presets that
arebuiltintothesystemorthathavebeenloaded
will show up here.
Loa d—Loads presets from the hard drive. Click
this button and then navigate to the directory
w ith your presets to load them into your Cloth
Properties.
Save—Saves your Cloth Properties parameters to a
file that you can then load at a later time.
Use T hese Pr operti es—Determines the cloth
properties from the settings on the rollout below.
Get From Object—Sets the cloth properties of the
group to b e the same as the object they a re selec ted
on.
