Create material from code and assign it to an object
<p>I am very new to Unity3d. I have a prefab which contains 6 quads making it a cube. I want to add image textures to different faces of cube.
I am getting images from a web service, so I have to add or change material in the script.
The problem I am facing is, I am not able to find material property in gameObject.</p>
<p>I have tried below code:</p>
<pre><code>using UnityEngine;
using System.Collections;

public class shelfRuntime : MonoBehaviour {
    public GameObject bottle;
    public GameObject newBottle;
    // Use this for initialization
    void Start () {
   
            iterateChildren(newBottle.transform.root);
        
        GameObject rocketClone = (GameObject)Instantiate(bottle, bottle.transform.position, bottle.transform.rotation);
        rocketClone.transform.localScale += new Vector3(1, 1, 1);
        GameObject newBottleInMaking = (GameObject)Instantiate(newBottle, newBottle.transform.position, newBottle.transform.rotation);

        Transform[] allChildren = newBottleInMaking.GetComponentsInChildren&lt;Transform&gt;();
        foreach (Transform child in allChildren)
        {
            // do whatever with child transform here
        }
    }
    void iterateChildren(Transform trans)
    {
        Debug.Log(trans.name);
        if (trans.name == &quot;Back&quot;) {
            var ting = trans.gameObject.GetComponent&lt;Renderer&gt;();
        //   trans.renderer.material  // there is no material property here 
        }

        // Do whatever logic you want on child objects here
        if (trans.childCount == 0) return;

        foreach (Transform tran in trans)
        {
            iterateChildren(tran);
        }
    }

    // Update is called once per frame
    void Update () {
    
    }
}
</code></pre>
