Enable/Disable Post Processing Effects

Hi there,

I would like to build a little menu to set the quality of my game. In this settings it should be possible to enable/disable effects like some post processings. Let's say there is a Bloom Effect and I want to enable and disable this one at runtime. How can I get access to it in a script.



I found a script but it doesn't work for me. It looks like this and I added this script to the Object, where the Bloom effect is added.

Code (CSharp):

1. Bloom bloomLayer;
2.  
3. PostProcessVolume volume = GetComponent<PostProcessVolume>();
4. volume.profile.TryGetSettings(out bloomLayer);

How is it possible to disable this effect via script?

Thanks

 

It appears the

Bloom

object is a

Component

on a

GameObject

. Make your

Bloom

variable public and drag that

GameObject

into it, or else use either

.GetComponent<Bloom>()

or

FindObjectOfType<Bloom>()

, and once you have a valid reference, I would imagine you could enable and disable it by setting the

.enabled

property in code.

Disclaimer: I have not used this particular class myself but I assume it works like 99.9% of everything else in Unity3D.

 

Thanks, but no, that doesn't work. I tried it before and in many different ways. That's the reason, why I create this post. :-/

 

Same here. Did you manage to solve it?

 

i d like to know too

 

Take OP's post and add this to the end:

Code (csharp):

1. bloomLayer.enabled.value = false;

 

I still cannot get it to work properly, the best way is probably to add each effect to its own volume and then just disable the volume gameobject. But I would like to know some better and faster options.

 

This worked for me
https://forum.unity.com/threads/toggle-single-post-processing-effect-on-of-with-toggle.758177/

 

Code (CSharp):

1. using UnityEngine.Rendering.PostProcessing;
2. using UnityEngine;
3.  
4. public class PostprocessingExtension : MonoBehaviour
5. {
6.           [SerializeField]private PostProcessProfile postProcessProfile;
7.        
8.        
9.           void Start()
10.            {
11.                 PostProcessingProfileIsEnabled(false,postProcessProfile);//true or false
12.            }
13.             private void PostProcessingProfileIsEnabled(bool isEnabled,PostProcessProfile postProcessProfile)
14.            {
15.                if(postProcessProfile == null) return;
16.                foreach (var item in postProcessProfile.settings)
17.               {
18.                        item.enabled.value = isEnabled;
19.                }
20.            }
21. }

OR

Below best solution

Code (CSharp):

1.  
2. using UnityEngine.Rendering.PostProcessing;
3. using UnityEngine;
4.  
5. public class PostprocessingExtension : MonoBehaviour
6. {
7.          
8.          [SerializeField]private PostProcessLayer postProcessLayer;
9.        
10.           void Start()
11.            {
12.                 SetPostProcessingLayerIsEnabled(false);//true or false
13.            }
14.          
15.          public void SetPostProcessingLayerIsEnabled(bool _value)
16.         {
17.             if(postProcessLayer == null) return;
18.                postProcessLayer.enabled = _value;
19.        }
20. }

 

You saved me thanks!

 

[SerializeField]
private PostProcessVolume _postProcessVolume;
