SoftDynamicBody3D
=================
**Inherits:** :ref:`MeshInstance3D<class_MeshInstance3D>` **<** :ref:`GeometryInstance3D<class_GeometryInstance3D>` **<** :ref:`VisualInstance3D<class_VisualInstance3D>` **<** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
A soft mesh physics body.
Description
-----------
A deformable physics body. Used to create elastic or deformable objects such as cloth, rubber, or other flexible materials.
\ **Note:** There are many known bugs in ``SoftDynamicBody3D``. 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).
