Webcam Script to display Webcam Textures [http://www.ikriz.nl/2011/12/23/unity-video-remake/]

Webcam.cs

using UnityEngine;

public class Webcam : MonoBehaviour
{
 
    public MeshRenderer[] UseWebcamTexture;
    private WebCamTexture webcamTexture;
    
    void Start()
    {
        webcamTexture = new WebCamTexture();
	foreach(MeshRenderer r in UseWebcamTexture)
	{
		r.material.mainTexture = webcamTexture;
	}
        renderer.material.mainTexture = webcamTexture;
        webcamTexture.Play();
   }

    void OnGUI()
    {
        if (webcamTexture.isPlaying)
        {
            if (GUILayout.Button("Pause"))
            {
                webcamTexture.Pause();
            }
            if (GUILayout.Button("Stop"))
            {
                webcamTexture.Stop();
            }
        }
        else
        {
            if (GUILayout.Button("Play"))
            {
                webcamTexture.Play();
            }
        }
    }
}

hello very good job!
I wanted to ask you for part of the code:

renderer.material.mainTexture = webcamTexture; //line 16

in unity3d.2017 it tells me that it is obsolete, do you know how to modify it?
Thank you
