Clo th Fo rces—
Add forces (that is, space warps in
thescene)suchaswindtothesimulation.Click

forces to the simulation, in the Forces In Scene
list on the left side, high light the forces to add,
and t hen click the > button to move them to the
Forces In Simulation list, t hus adding them to the
simulation. Thereafter, the forces affect all cloth
objects in the simulation.
To remove forces from the simulation, in the Forces
In Simulation list on the r ight side, high light the
forces to remove, and then click the < button to
move them to the Forces In Scene list.
Simulation group
To run a cloth simulation, click any of the
threeSimulatebuttonsinthisgroup. Tohalta
simulation, press ESC or if the Cloth Simulation
dialog is open (i.e.,
Progress is on), click the
Cancel button.
Simulate Local—Starts the simulation process
without creating animation. Use this to drape
the clothes on a character or sew the panels of a
garment together.
Simu lat e Local (da mped)—Same as Simulate Loca l,
butwithalargeamountofdampingaddedto
the cloth. When sew ing a garment together,
sometimes the panels come together at high speed,
causing problems. Using a damped simulation
alleviates this problem.
Simulate—Creates a simulat ion over the active
time segment. Unlike Simulate L ocal, this creates
animationdataintheformofasimulationcache
at every frame.
Progres s—When on, opens the Cloth Simulation
dialog during the simulation. The dialog shows the
progress of the simulation, including information
about time, and messages about errors or time
step size adjustments.
The Cloth Simulation dialog shows i nformation about the
simulation while it ’s running.
Simu lat ed Fra mes—Shows the number of frames
simulated so far.
Erase S imulation—Deletes the current simulation.
This deletes the cache of all cloth objects and sets
the Simulated Frames count back to 1.
Truncate Simu latio n—Deletes animation created by
the simulation after the current fr ame.
For example, if you’ve simulated an animation to
frame 50 but want to keep only animation keys
from frames 0 to 30, set the time slider to frame
30,thenclickthisbutton.Thesimulationisthen
