Error on change Bloom intensity with Cinemachine + Post Processing

Hello everyone!

I use Unity 2019 and ever use the package manager to give Cinemachine and Post Processing (v2)

I'm trying to access the Bloom effect and change its intensity value.

I don't get errors in Visual Studio or Unity on standby, but when I go to test, the Unity gaves me this error:

My code is like this:

Code (CSharp):

1.     public CinemachinePostProcessing PostFX;
2.  
3.     void Start()
4.     {
5.         var bloom = PostFX.GetComponent<Bloom>();
6.         bloom.intensity.value = 30f;
7.     }

Visual Reference:


Any idea to fix this and access the bloom intensity parameter?

Thanks in advance

 

I think you may have accidentally omitted the error!

 

Oh, is true! Sorry, friend!

Here:

 

It looks like Bloom is not a component so you'll need to access it in as different way than using the GetComponent<> method directly. It looks like it might be part of the Cinemachine Post-Process Volume component. So you might have to get that first. I don't know enough about the Cinemachine API off the top of my head to know exactly what the path to the Bloom object is.

 

Thanks to answer, friend! I'll to try this now and back here with the same or with a solution. I hope the solution, really haha

Hugs!

 

Hi. Thanks again. i got it make! Your answer opened my vision. I'll leave the solution for who comes later.

To access Post Process Volume params, normally we use:

Code (CSharp):

1. camera.profile.TryGetSettings(out param);

with Cinemachine, need access with m_Profile, not profile

The solution is very simple (at least on Unity 2019):

Spoiler

Code (CSharp):

1. using UnityEngine;
2. using Cinemachine.PostFX;
3. using UnityEngine.Rendering.PostProcessing;
4.  
5. public class MyClass : MonoBehaviour
6. {
7.         public CinemachinePostProcessing PPvCam;
8.         private Bloom bloom;
9.  
10.         void changePostFXParams()
11.         {
12.                 PPvCam.m_Profile.TryGetSettings(out bloom);
13.                 bloom.enabled.value = true;
14.                 bloom.intensity.value = 10f;
15.         }
16. }

in this case, intensity is this param (in yellow):

The params have de same name of the inspector, then just type bloom variable dot param name

Other example to help any that comes later:

Code (CSharp):

1. using UnityEngine;
2. using Cinemachine.PostFX;
3. using UnityEngine.Rendering.PostProcessing;
4.  
5. public class MyClass : MonoBehaviour
6. {
7.         public CinemachinePostProcessing PPvCam; //my cinemachine virtual camera
8.  
9.         private Bloom bloomParam; //my bloom fx
10.         private ColorGrading colorGradeParam; //my color grading fx
11.         private DepthOfField dofParam; //my depth of field fx
12.  
13.         void changePostFXParams()
14.         {
15.                 //Get the post-processing volume params from cinemachine camera
16.                 PPvCam.m_Profile.TryGetSettings(out bloomParam);
17.                 PPvCam.m_Profile.TryGetSettings(out colorGradeParam);
18.                 PPvCam.m_Profile.TryGetSettings(out dof);
19.  
20.                 //Set Active
21.                 bloomParam.enabled.value = true;
22.                 colorGradeParam.enabled.value = true;
23.  
24.                 //Set Bloom Values
25.                 bloomParam.intensity.value = 5f; //Intensity
26.                 bloomParam.color.value = Color.red; //Color
27.  
28.                 //Set Color Grading Values
29.                 colorGradeParam.colorFilter.value = Color.blue; //Color Filter
30.  
31.                 //Set Depth of Field values
32.                 dofParam.focusDistance.value = 1f; //focus Distance
33.         }
34. }

Thanks and per your atention!

 

I'm trying to do a similar method in my 2020.1.1f URP project but I seem to not be able to get the bloom component. I'm using Cinemachine and under the virtual camera component, there are extensions and one of the extensions are the post-processing volumes where I can access bloom but I can't access it in bloom? What should I do?

 

@Octoverse OMG thank you!! Why was this solution so hard to find, this is exactly what I've been looking the past 2 hours for haha

 

you're welcome!
