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