Post processing effects

Hello can anyone help me increment the intensity setting on the post processing vignette via script?
I looked at the API and im having a hard time wrapping my head around it


For further context, im making a script that increases the vignette intensity setting by 1 as Time.delta time increases

 

Are you using either the post-processing in HDRP, or Post Processing Stack V2?

If so, then you should be able to get a handle on the Vignette object. Make sure you've check the box to allow overrides to the intensity. Then, in code, you can just do something like this:

Code (CSharp):

1. _postProcessingVignette.intensity.Override(someFloatValue);

That will set the intensity to whatever 'someFloatValue' equals. If you want to do this over time, you can either set this in an Update statement, or in a coroutine.

 

I'm using post processing stack V2, im not quiet sure how to call it.

i tried making a public vignette
but I can't drag it in

 

Your script should have a public property for either the VolumeProfile, or the Volume that the profile is on. Then you can call

profile.GetComponent<Vignette>()

to get the Vignette component.

Here's a simplified example from my code. This is using HDRP's post processing, but I think it's nearly identical to V2.

Code (CSharp):

1. public Volume RenderVolume;
2.  
3. private Vignette _postProcessingVignette;
4.  
5. void Start() {
6.     _postProcessingVignette = RenderVolume.profile.GetComponent<Vignette>();
7. }
8.  
9. void Update() {
10.     _postProcessingVignette.intensity.Override(whateverTheIntensityShouldBe);
11. }

 

apparently "Post processprofile does not contain a defnition for get component"
what should i used instead?

 

You probably have a typo or something. Show your code, both the code that calls GetComponent, and the code that declares the variable you're calling it on.

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Rendering.PostProcessing;
5.  
6. public class PostProcessing : MonoBehaviour
7. {
8.     public PostProcessVolume RenderVolume;
9.  
10.     private Vignette _postProcessingVignette;
11.  
12.     void Start()
13.     {
14.         _postProcessingVignette = RenderVolume.profile.GetComponent<Vignette>();
15.     }
16.  
17.     // Update is called once per frame
18.     void Update()
19.     {
20.  
21.         _postProcessingVignette.intensity.Override(1);
22.     }
23. }
24.  

 

Ah, sorry about that. My fault. I completely forgot I created an extension method (a code shortcut) so I could call GetComponent on a volume. Instead, of GetComponent, you'll need something like this:

(Note: This is for HDRP. For PPv2, change "components" to "settings".)

_postProcessingVignette = RenderVolume.profile.components.FirstOrDefault(c => c is Vignette) as Vignette;

Be sure to add

using System.Linq;

to use this.


And here's that extension method, though, in case you want to use it, since the above code is kind of awkward:

Code (CSharp):

1.     public static class VolumeProfileUtil
2.     {
3.  
4.         public static T GetComponent<T>(this VolumeProfile profile) where T : VolumeComponent
5.         {
6.             // Note: This is for HDRP. For PPv2, change "components" to "settings".
7.             return profile.components.FirstOrDefault(s => s is T) as T;
8.         }
9.  
10.     }

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Rendering.PostProcessing;
5. using System.Linq;
6.  
7. public class PostProcessing : MonoBehaviour
8. {
9.     public PostProcessVolume RenderVolume;
10.  
11.     private Vignette _postProcessingVignette;
12.  
13.     void Start()
14.     {
15.         _postProcessingVignette = RenderVolume.profile.components.FirstOrDefault(c => c is Vignette) as Vignette;
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.  
22.         _postProcessingVignette.intensity.Override(1);
23.     }
24.  
25.  
26. }
27.  
28. components still seems to be highlighted and saying there is no assembly reference
29.  

 

Looks like in HDRP, it's called "components", while in PPv2 it's called "settings". Just change ".components" to ".settings" and I think it should work.

 

You are my hero thank you so much
