This tool is used for a static object that influences a Cloth Object. It is similar to the Volume Collider, the main difference being that the Surface Collider interacts with polygons and the Volume Collider interacts with volumes.

You should use a Surface Collider if your static object is moving around and colliding with cloth, such as for the body of a character interacting with clothing. You should use a Volume Collider if your object is not deforming, for example for a terrain that a cloth object is interacting with.

1. Select the geometry to convert to a static object.

2. Click the Surface Collider tool on the Cloth or Solid tab.
