本文介绍了一个Unity脚本，用于将场景中的多个网格合并成一个，并提供了保存合并后网格的方法。通过使用MeshFilter组件，该脚本可以有效减少Draw Call，提高渲染效率。

        int i = 0;  
        while (i < meshFilters.Length)  
        {  
            combine[i].mesh = meshFilters[i].sharedMesh;  
            combine[i].transform = meshFilters[i].transform.localToWorldMatrix;  
            meshFilters[i].gameObject.SetActive(false);  
            i++;  
        }  
  
        transform.GetComponent<MeshFilter>().mesh = new Mesh();  
        transform.GetComponent<MeshFilter>().mesh.CombineMeshes(combine);  
        transform.gameObject.SetActive(true);  
    }  
}
