public static void Combine(GameObject staticBatchRoot);

Parameters

staticBatchRoot The GameObject that should become the root of the combined batch.

Description

StaticBatchingUtility.Combine prepares all children of the staticBatchRoot for static batching.

A GameObject is only eligible for static batching using this method when all of the following criteria are met:

  • The GameObject is active.
  • The GameObject has a Mesh Filter component, and that component is enabled.
  • The Mesh Filter component has a reference to a Mesh.
  • The Mesh is read/write enabled.
  • The Mesh has a vertex count greater than 0.
  • The Mesh has not already been combined with another Mesh.
  • The GameObject has a Mesh Renderer component, and that component is enabled.
  • The Mesh Renderer component does not use any Material with a shader that has the DisableBatching tag set to true.

When you use this method, you do not need to mark a GameObject as Batching Static using the Inspector window’s Static check box to make it eligible for batching.

Once combined, children cannot change their Transform properties; however, you can change the transform properties of staticBatchRoot.
