Resolved How to run my CS function at a specific pass ?

Hello,
I've digged around the web and I havn't found a clear example of what I'm trying to achieve.

Say this picture with all the passes from HDRP that can be found in the doc here https://docs.unity3d.com/Packages/c...s.high-definition@7.1/manual/Custom-Pass.html

Say my CS script function

Code (CSharp):

1. using UnityEngine;
2.  
3. public class MainCamera : MonoBehaviour {
4.  
5.     void OnPreCull () {
6.         Debug.Log("This function was called on the specific pass");
7.     }
8. }

OnPreCull doesn't work anymore as said here https://forum.unity.com/threads/fee...e-render-pipelines.470095/page-8#post-3408481

How can I let's say inject my code on "BeforeRendering" like :

Code (CSharp):

1. using UnityEngine;
2.  
3. public class MainCamera : MonoBehaviour {
4.  
5.     void BeforeRendering() {
6.         Debug.Log("This function was called on the specific pass");
7.     }
8. }

Is there a way to run my CS function at a certain point of the HDRP passes ?
I tryed to use the custom pass script, but it seem to require a material, and it was pretty obscure, I just want my CS function to run at a certain point.

Thank you for any answers !

 

I do tried to make a custom pass :

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Rendering;
3. using UnityEngine.Rendering.HighDefinition;
4.  
5. public class CustomPassPortal : CustomPass
6. {
7.     public MainCamera mc;
8.  
9.     protected override void Setup(ScriptableRenderContext renderContext, CommandBuffer cmd) { }
10.  
11.     protected override void Execute(ScriptableRenderContext renderContext, CommandBuffer cmd, HDCamera camera, CullingResults cullingResult) {
12.         mc.debugBeforeRendering();
13.     }
14.  
15.     protected override void Cleanup() { }
16. }

The idea was to trigger my camera debugBeforeRendering function.
But the script inside the Execute function of the CustomPassPortal class is never called.
And I do not know why...

 

Restarting the scene seemed to do the trick.
