Use the same webcamtexture on multiple objects

Question

UPDATE: In scene view it seems changing the position of the blocks while the game is started, turns the webcamtexture on and off.

I'm attempting to use the live feed of a webcam as a texture on multiple objects. Within the objects that are meant to display the feed I have the following script

 private WebCamTexture _webcamTexture;
 private Renderer _renderer;
 void Start () {
     _webcamTexture = new WebCamTexture ();
     

     _renderer = GetComponent<Renderer> ();
     _renderer.material.mainTexture = _webcamTexture;
     _webcamTexture.Play ();

 }

It works fine on one. But it does not work on multiple objects. I also attempted making the texture a global static and having each object access the texture instead of everyone making their own however that didn't resolve the issue. I've been able to get it to render on 2 cubes but not more than that.

Try applying the texture to a material.

  // Assign the Material you are using for the web cam feed
     [SerializeField] private Material webCamTex;  
 
     void Start()
     {
         // Grabbing all web cam devices
         WebCamDevice[] devices = WebCamTexture.devices;
 
         // I just use the first one, use which ever one you need 
         string camName = devices[0].name;
 
         // set the Texture from the cam feed
         WebCamTexture camFeed = new WebCamTexture (camName);
 
         // Assign the materials texture to the WebCamTexture you made,
         // this applies it to all objects using this Material
         webCamTex.mainTexture = camFeed;
 
         // Then start the texture
         camFeed.Play ();    
     }

If you just use this one script and add the texture to another renderer it should work:

webCamTex.mainTexture = camFeed; other_renderer.material.mainTexture = camFeed;

If you use the same script on 2 objects it won't work (it doesn't for me at least).
