MultiMesh
=========
**Hereda:** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
Provides high-performance drawing of a mesh multiple times using GPU instancing.
.. rst-class:: classref-introduction-group
Descripción
----------------------
MultiMesh provides low-level mesh instancing. Drawing thousands of :ref:`MeshInstance3D<class_MeshInstance3D>` nodes can be slow, since each object is submitted to the GPU then drawn individually.
MultiMesh is much faster as it can draw thousands of instances with a single draw call, resulting in less API overhead.
As a drawback, if the instances are too far away from each other, performance may be reduced as every single instance will always render (they are spatially indexed as one, for the whole object).
Since instances may have any behavior, the AABB used for visibility must be provided by the user.
\ **Note:** A MultiMesh is a single object, therefore the same maximum lights per object restriction applies. This means, that once the maximum lights are consumed by one or more instances, the rest of the MultiMesh instances will **not** receive any lighting.
\ **Note:** Blend Shapes will be ignored if used in a MultiMesh.

When using *physics interpolation*, this function allows you to prevent interpolation on an instance in the current physics tick.

An alternative to setting the :ref:`buffer<class_MultiMesh_property_buffer>` property, which can be used with *physics interpolation*. This method takes two arrays, and can set the data for the current and previous tick in one go. The renderer will automatically interpolate the data at each frame.
This is useful for situations where the order of instances may change from physics tick to tick, such as particle systems.
When the order of instances is coherent, the simpler alternative of setting :ref:`buffer<class_MultiMesh_property_buffer>` can still be used with interpolation.

|void| **set_instance_color**\ (\ instance\: :ref:`int<class_int>`, color\: :ref:`Color<class_Color>`\ ) :ref:`🔗<class_MultiMesh_method_set_instance_color>`
Sets the color of a specific instance by *multiplying* the mesh's existing vertex colors. This allows for different color tinting per instance.
\ **Note:** Each component is stored in 32 bits in the Forward+ and Mobile rendering methods, but is packed into 16 bits in the Compatibility rendering method.
For the color to take effect, ensure that :ref:`use_colors<class_MultiMesh_property_use_colors>` is ``true`` on the **MultiMesh** and :ref:`BaseMaterial3D.vertex_color_use_as_albedo<class_BaseMaterial3D_property_vertex_color_use_as_albedo>` is ``true`` on the material.

For the custom data to be used, ensure that :ref:`use_custom_data<class_MultiMesh_property_use_custom_data>` is ``true``.
This custom instance data has to be manually accessed in your custom shader using ``INSTANCE_CUSTOM``.
