	<description>
		MeshInstance 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 to get 3D geometry rendered and can be used to instance a single [Mesh] in many places. This allows to reuse geometry and save on resources. When a [Mesh] has to be instanced more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance] instead.

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

			<return type="void">
			</return>
			<description>
				This helper creates a [MeshInstance] child node with gizmos at every vertex calculated from the mesh geometry. It's mainly used for testing.

		<method name="get_active_material" qualifiers="const">
			<return type="Material">
			</return>
			<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 GeometryInstance.material_override], the surface override [Material] defined in this [MeshInstance], or the surface [Material] defined in the [Mesh]. For example, if [member GeometryInstance.material_override] is used, all surfaces will return the override material.

			<argument index="0" name="surface" type="int">
			</argument>
			<description>
				Returns the [Material] for a 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.
