Question Apply material shader on texture.

Hello. I would like to apply shader on texture to rotate it. I've chosen this way, because after that I want save series of rotations in png. Here is my code:

Code (CSharp):

1. public class Test : MonoBehaviour
2.     {
3.         public Texture2D texture;
4.         public Material rotateShader;
5.         public float timer;
6.  
7.         private Renderer _rend;
8.         // Start is called before the first frame update
9.         void Start()
10.         {
11.             _rend = gameObject.GetComponent<Renderer>();
12.         }
13.  
14.         private float _t = 0.0f;
15.  
16.         private float degrees = 0.0f;
17.         // Update is called once per frame
18.         void Update()
19.         {
20.             if (_t >= timer)
21.             {
22.                 // rotateShader.SetFloat("Degrees", degrees);
23.                 RenderTexture renderTexture = RenderTexture.GetTemporary(texture.width, texture.height, 0);
24.                 Texture2D temp = new(texture.width, texture.height, DefaultFormat.LDR, TextureCreationFlags.None);
25.                 Graphics.Blit(texture, renderTexture, rotateShader);
26.                 Graphics.CopyTexture(renderTexture, temp);
27.                 _rend.material.mainTexture = temp;
28.                 RenderTexture.ReleaseTemporary(renderTexture);
29.                 _t = 0.0f;
30.                 degrees += 5.0f;
31.             }
32.  
33.             _t += Time.deltaTime;
34.         }
35.     }

Here is my shader:


For some reason I've got this:



Where I'm doing some thing wrong?

 

Looks like it doesn't work in URP.
