After you've created a force for the cloth object, you need to set up how the cloth reacts to the force.
Apply forces to the cloth object by selecting the force and choosing Modify Cloth Apply Force from the Simulate toolbar (see Creating and Applying a Force for more information).
Open the cloth object's ClothOp property editor by clicking the ClothOp node's icon in the explorer.
Click the External Forces tab and set the parameters.
The settings you use here represent a percentage of the "global" effect that the force has.
Modify the properties that correspond to the force acting on the cloth. You must use any value greater than 0 (zero) for these parameters for the appropriate force to have an effect.
