error CS0029: Cannot implicitly convert type 'string' to 'UnityEngine.RenderTextureFormat'

I am working on portals for my game and to make them seamless, I am using render textures to display the environment the player is supposed to teleport to.

The only thing that wasn't getting "carried over" to the render texture is post-processing; and to get it to work I found colour format needed, but I don't know which variable format is required to apply it to the render texture through script.

"Assets\Scripts\Player system\PortalViewAdjustment.cs(21,40): error CS0029: Cannot implicitly convert type 'string' to 'UnityEngine.RenderTextureFormat'​

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PortalViewAdjustment : MonoBehaviour
6. {
7.     public Camera cameraB;
8.     public Material cameraMatB;
9.     public Camera cameraA;
10.     public Material cameraMatA;
11.  
12.  
13.     // Start is called before the first frame update
14.     void Start()
15.     {
16.         if (cameraB.targetTexture != null)
17.         {
18.             cameraB.targetTexture.Release();
19.         }
20.         cameraB.targetTexture = new RenderTexture(Screen.width , Screen.height , 24);
21.         cameraB.targetTexture.format = "R32G32B32A32_SFLOAT";
22.         cameraMatB.mainTexture = cameraB.targetTexture;
23.  
24.         if (cameraA.targetTexture != null)
25.         {
26.             cameraA.targetTexture.Release();
27.         }
28.         cameraA.targetTexture = new RenderTexture(Screen.width, Screen.height, 24);
29.         cameraA.targetTexture.format = "R32G32B32A32_SFLOAT";
30.         cameraMatA.mainTexture = cameraA.targetTexture;
31.     }
32. }
33.  

 

If you want to assign targetTexture.format a RenderTextureFormat, then you cannot use a string.

Code (CSharp):

1. cam.targetTexture.format = RenderTextureFormat.RGB111110Float; // a format that is defined

Hope this helps

 

Thank you for your reply, but this solution gives me the following error:

Setting color format of already created render texture is not supported!
UnityEngine.RenderTexture:set_format (UnityEngine.RenderTextureFormat)
PortalViewAdjustment:Start () (at Assets/Scripts/Player system/PortalViewAdjustment.cs:29)​

Have I done something wrong?
