Cloth Modifier
The Cloth modifier is a container for a Cloth Physics simulation. It can be useful for example, to simulate on a low-poly mesh then add a Subdivision Surface Modifier after the Cloth modifier to improve the visual quality of the cloth without drastically increasing simulation times.
Options(オプション)
As the modifier is only a container its actual options can be configured in the Physics Properties tab. See the Cloth Physics Properties for more information.
