		A deformable 3D physics mesh.
	</brief_description>
	<description>
		A deformable 3D physics mesh. Used to create elastic or deformable objects such as cloth, rubber, or other flexible materials.
		Additionally, [SoftBody3D] is subject to wind forces defined in [Area3D] (see [member Area3D.wind_source_path], [member Area3D.wind_force_magnitude], and [member Area3D.wind_attenuation_factor]).
		[b]Note:[/b] It's recommended to use Jolt Physics when using [SoftBody3D] instead of the default GodotPhysics3D, as Jolt Physics' soft body implementation is faster and more reliable. You can switch the physics engine using the [member ProjectSettings.physics/3d/physics_engine] project setting.

		<method name="apply_central_force">
			<return type="void" />
			<param index="0" name="force" type="Vector3" />
			<description>
				Distributes and applies a force to all points. A force is time dependent and meant to be applied every physics update.
