Soft cloth is an incredibly versatile feature that can be used for hanging, swaying, or rolling motions in your scene. You can use the pin option to adjust the gray area of the weight map to dictate the dynamic controls for certain types of physics performances. Wind behavior is also added to make soft clothes self-animated, allowing for much more natural movement without external animation forces.
