For this recipe, we need a model of the cloth. It should be a plane divided several times to have enough vertices for the cloth simulation to work. In our example, we use one additional model: the flag pole. You can go to the Chapter 09 Physics and animationsRecipe 01 Using cloth directory. You will find a FlagPole game object in the Example.unity scene there. This object contains the Flag and the FlagPole objects as children. The Flag game object uses the cloth simulation.
