Simulate Local—Starts local simulation of the cloth.
In order for the real-time interactive feedback with
the cloth to occur, this button must be on.

Sim on mouse down—Runs the local simulation
only when the left mouse button is clicked. This
mode is usually preferred since you can start and
stop the local simulation simply by releasing the
mouse button. As a result, it makes it far easier to
position and rotate the faces of your cloth within
your scene.
Ignore B a ck fa cing—When on, you can select only
faces facing you. When off (the default), you can
select any faces under the mouse curs or, regardless
of visibility or facing.

Procedure
Ex ample: To use t he K eep S hape opt ion:
If your cloth object starts out with 3D shape that
you’d like to retain during the simulation, you
can use the Keep Shape option and setting to
preserve this shape, or even reverse it. This simple
procedure provides an example of how to use Keep
Shape.
1. Add a Plane primitive object of about 90 x 90
units, with 20 x 20 segments.
2. Apply a Bend modifier, set Angle to 250.0,and
set Bend Axis to X.
This produces the initial tubular shape.
3. Copy the bent plane twice so you have three
planes in a row. Rename the planes as follows:
• don’t kee p sha pe
• keep s ha p e
• reverse s hape
4. Select all three planes and apply the Cloth
modifier.
5. On the Simulation Parameters rollout, turn off
Gravity and set cm/unit to 0.5.
Turning off Gravity keeps the cloth objects
from fal l ing during the simulation, so the y
