Declaration

public static void Combine(GameObject staticBatchRoot);

Parameters

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

Description

Combines all children GameObjects of the staticBatchRoot for static batching.

Static batching is a draw call batching method that combines meshes that don't move to reduce draw calls. For more information about static batching, see Static batching.

This method copies the mesh data of the GameObjects into a single internal mesh. Each original GameObject is still present in the Scene which means Unity can still cull them individually.

All child GameObjects under the staticBatchRoot must be eligible for static batching. For information on the eligibility requirements for static batching, see Static batching at runtime.

After you combine the GameObjects, you can't change the Transform properties of the children. However, you can change the Transform properties of the staticBatchRoot. Doing so transforms the entire combined batch.

Note: You don't need to use this method with GameObjects you marked as Batching Static in the Editor. Unity prepares these GameObjects for static batching when it builds the Player.
