 		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] There are many known bugs in [SoftBody3D]. Therefore, it's not recommended to use them for things that can affect gameplay (such as trampolines).
+		[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.
