	<description>
		MeshInstance3D is a node that takes a [Mesh] resource and adds it to the current scenario by creating an instance of it. This is the class most often used render 3D geometry and can be used to instance a single [Mesh] in many places. This allows reuse of geometry which can save on resources. When a [Mesh] has to be instanced more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance3D] instead.

			<description>
				This helper creates a [StaticBody3D] child node with a [ConvexPolygonShape3D] collision shape calculated from the mesh geometry. It's mainly used for testing.

			<description>
				This helper creates a [MeshInstance3D] child node with gizmos at every vertex calculated from the mesh geometry. It's mainly used for testing.

			<argument index="0" name="surface" type="int">
			</argument>
			<description>
				Returns the [Material] that will be used by the [Mesh] when drawing. This can return the [member GeometryInstance3D.material_override], the surface override [Material] defined in this [MeshInstance3D], or the surface [Material] defined in the [Mesh]. For example, if [member GeometryInstance3D.material_override] is used, all surfaces will return the override material.

		<method name="get_surface_material" qualifiers="const">
			<return type="Material">

			<argument index="0" name="surface" type="int">
			</argument>
			<description>
				Returns the override [Material] for the specified surface of the [Mesh] resource.
			</description>
		</method>
		<method name="get_surface_material_count" qualifiers="const">
			<return type="int">
			</return>
			<description>
				Returns the number of surface materials.

			<description>
				Sets the override [Material] for the specified surface of the [Mesh] resource. This material is associated with this [MeshInstance3D] rather than with the [Mesh] resource.
