Cloth Modifier 591
Surf ace—
Attaches the selected group to the surface
of a collision object in the scene. To use, click
Surface, and then select the node for attaching.
Tip: This constraint is best suited for when the cloth
and the constraining object should be in close
proximity, such as with clothing on a character
mesh.
Clo th—Attaches the selected group of cloth vert ices
to another cloth object.
Preserv e—This group type preserves the motion
from below the Cloth modifier in the modifier
stack. For example, you m i ght have a dress that
you’ve skinned to a sk eleton. You want the upper
portion of the dress to be unaffec ted by the Cloth
simulation (that is, to retain its deformation
defined by the sk inning), and the lower part to
be simulated. In this case, you’d ma ke a Preserve
constraint from the upper vertices.
Drag—This group type locks the vertices in place
or adds a damping force to selected group. When
Group Parameters rollout > Soft is off, you c an
use this constraint for “nailing” vertices in place
sothattheydonotmoveatall.WhenSoftison,
theverticeswillhaveadragforceappliedwhere
the amount of drag is controlled by the Strength
and Damping values, a lso on the Group Properties
rollout.
SimNode—This option works the same as the Node
option, except the node must be part of the Cloth
simulation.
Group—Attaches one group to another. This is
recommended only for single-ver tex groups. (that
is, groups that contain only one vertex). With this,
you can make one cloth vertex stick to another
cloth vertex. Select one group , click this button
to open the Pick Group dialog , an d then choose
another group.
NoCollide—Causes collisions between the currently
selected group and another g roup to be ignored.
When you click this button, you’re prompted to
choose another group. You could use this option
to prevent the simulator from processing collisions
between cloth and the body under an arm or
between the legs.
Forcefield—Allows you to link a group to a space
warp and have the space warp affect the vertices.
Sticky Sur f—The g roup sticks to a surface only
after it has collided with that sur f ace. Solid Coll
must be enabled for this constraint to work.
Sticky Cloth—The g roup sticks to a surface only
after it has collided with that surface. Self Coll must
be enabled for this constraint to work.
[group list]—Shows all current groups. The
number of vertices associated with the h ighlighted
group is shown below t he list. To assign, copy,
paste, delete or alter a created group, first highlight
the group name in the list.
Co py—Copies a named select ion set to the copy
buffer.
Pas t e—Pastes the named selection set f rom copy
buffer.
Group Parameters rollout
The Group Parameters rollout appears after you
use Make Group on a vertex selection to create at
least one group. Thereafter, high light the group
