Description
|
|
-----------
|
|
|
|
Node used for displaying a :ref:`Mesh<class_Mesh>` in 2D. This can be faster to render compared to displaying a :ref:`Sprite2D<class_Sprite2D>` node with large transparent areas, especially if the node takes up a lot of space on screen at high viewport resolutions. This is because using a mesh designed to fit the sprite's opaque areas will reduce GPU fill rate utilization (at the cost of increased vertex processing utilization).
|
|
|
|
When a :ref:`Mesh<class_Mesh>` has to be instantiated more than thousands of times close to each other, consider using a :ref:`MultiMesh<class_MultiMesh>` in a :ref:`MultiMeshInstance2D<class_MultiMeshInstance2D>` instead.
|
|
|
|
A **MeshInstance2D** can be created from an existing :ref:`Sprite2D<class_Sprite2D>` via a tool in the editor toolbar. Select the :ref:`Sprite2D<class_Sprite2D>` node, then choose **Sprite2D > Convert to MeshInstance2D** at the top of the 2D editor viewport.
