For more information about batching, refer to Introduction to batching meshes.
Note: Unity uses additional CPU memory to store the combined meshes, even if the meshes are the same. For example, marking trees as static in a dense forest environment can have a large impact on memory. If static batchingA technique Unity uses to draw GameObjects on the screen that combines static (non-moving) GameObjects into big Meshes, and renders them in a faster way. More info
See in Glossary uses too much memory, combine meshes manually instead.
To batch static GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary at runtime, for example GameObjects you create procedurally, follow these steps:
Select each meshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info
See in Glossary you want to batch, then in the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary window enable Read/Write enabled.
Use the StaticBatchingUtility API to batch the meshes. The StaticBatchingUtility.Combine method combines GameObjects and prepares them for static batching.
Note: To avoid the read/write mesh using double the amount of memory, you can now delete one copy of the mesh by calling the Mesh.UploadMeshData API with markNoLongerReadable set to true.
You don’t need to enable the static batching setting in the URP Asset, HDRP Asset, or Player SettingsSettings that let you set various player-specific options for the final game built by Unity. More info
See in Glossary.
If a mesh is culled because it’s outside the cameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary view, Unity might split the batch into two batches, to avoid a gap in the combined vertex buffers.
You can only change the position, rotation, and scale of the whole batch at runtime, not the individual meshes.
To batch moving GameObjects, enable dynamic batchingAn automatic Unity process which attempts to render multiple meshes as if they were a single mesh for optimized graphics performance. The technique transforms all of the GameObject vertices on the CPU and groups many similar vertices together. More info
See in Glossary.
Warning: For most uses, dynamic batching is no longer recommended, because the CPU overhead can be greater than the overhead of a draw call. If you use URP or HDRP, use the Scriptable Render Pipeline (SRP) Batcher instead. For more information, refer to Choose a draw call optimization method.
Follow these steps in the Built-In Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
