Bug LocalKeyword not recognized

Hi, I created a new Unity project, and just created a script like in this documentation example :

https://docs.unity3d.com/ScriptReference/Material.EnableKeyword.html

I wrote the same script :

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Rendering;
3.  
4. public class MaterialKeywordExample : MonoBehaviour
5. {
6.     public Material material;
7.     private LocalKeyword exampleFeatureKeyword;
8.  
9.     void Start()
10.     {
11.         // Get the instance of the Shader class that this material uses
12.         var shader = material.shader;
13.  
14.         // Create and cache the LocalKeyword
15.         exampleFeatureKeyword = new LocalKeyword(shader, "EXAMPLE_FEATURE_ON");
16.     }
17.  
18.     public void EnableExampleFeature()
19.     {
20.         material.EnableKeyword(exampleFeatureKeyword);
21.     }
22.  
23.     public void DisableExampleFeature()
24.     {
25.         material.DisableKeyword(exampleFeatureKeyword);
26.     }
27. }

and LocalKeyword is not recognized by visual studio, as well as keywordSpace and others...



the error in the console is the following : The type or namespace name 'LocalKeyword' could not be found (are you missing a using directive or an assembly reference?)

well I have visual studio editor last package installed


how to make visual studio recognize LocalKeyword ?

why doesn't he recognize it ?

thanks !!

 

What version of Unity are you on? This seems to be a 2021+ feature.
