Help with turning off a camera shader with an on trigger collider.

I'm using the stylizer shader from the asset store.
I keep getting the error
"Assets/mystuff/myscripts/TriggerEventGameObject.cs(27,32): error CS0246: The type or namespace name `Stylizer' could not be found. Are you missing `Beffio.Dithering' using directive?"
on
(MainCamerared.GetComponents<Stylizer> ().enabled = false; )

Can anyone help me figure this out I've tried digging online but everything seems to be outdated and I'm not that great at writing scripts?

Code (CSharp):

1. public class TriggerEventGameObject : MonoBehaviour {
2.  
3.  
4.  
5.     public GameObject player;
6.     public GameObject MainCamerared;
7.     public GameObject BlackBox;
8.  
9.  
10.     void Start () {
11.  
12.  
13.      
14.     }
15.  
16.  
17.     void OnTriggerEnter (Collider other) {
18.  
19.         if (other.CompareTag ("Player")) {
20.      
21.      
22.             BlackBox.GetComponent<MeshRenderer> ().enabled = false;
23.             MainCamerared.GetComponents<Stylizer> ().enabled = false;
24.         }
25.  
26.     }
27. }

 

Add on your script

using NamespaceOfYourImageEffect;

or use it like this

MainCamerared.GetComponents<NamespaceOfYourImageEffect.Stylizer> ().enabled = false;
