using System.Collections.Generic;

public class MyMeshClass : MonoBehaviour {

    void Start()

    {

        MeshFilter[] meshFilters = GetComponentsInChildren<MeshFilter>();

        CombineInstance[] combine = new CombineInstance[meshFilters.Length];

        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);
