	<brief_description>
		A soft mesh physics body.
	</brief_description>
	<description>
		A deformable physics body. Used to create elastic or deformable objects such as cloth, rubber, or other flexible materials.
		[b]Note:[/b] There are many known bugs in [SoftBody]. Therefore, it's not recommended to use them for things that can affect gameplay (such as a player character made entirely out of soft bodies).

			The physics layers this SoftBody is in.
			Collidable objects can exist in any of 32 different layers. These layers work like a tagging system, and are not visual. A collidable can use these layers to select with which objects it can collide, using the collision_mask property.
			A contact is detected if object A is in any of the layers that object B scans, or object B is in any layer scanned by object A. See [url=$DOCS_URL/tutorials/physics/physics_introduction.html#collision-layers-and-masks]Collision layers and masks[/url] in the documentation for more information.
