Question Adjust Aperture at runtime

I'd like to adjust the aperture of the Depth of Field via the Cinemachine Volume Settings. Alas, it's not working as I expect.

As you can see in the video below, I can adjust the aperture in editor no problem.
But at runtime when I manipulate the aperture by code, the effect does change - despite seeing the value change in the inspector.

Below is the code I'm using to change the aperture value. I feel like I must be missing something.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using MalbersAnimations.Scriptables;
5. using Cinemachine.PostFX;
6. using UnityEngine.Rendering.Universal;
7.  
8. public class SetFocusTransform : MonoBehaviour
9. {
10.     public TransformVar focusTarget;
11.     public CinemachineVolumeSettings volumeSettings;
12.     [Tooltip("If -1, override is disabled.")]
13.     public float overrideAperture = -1f;
14.     DepthOfField depthOfField;
15.     float apertureValueAtEnable;
16.  
17.     private void OnEnable()
18.     {
19.         volumeSettings.m_FocusTarget = focusTarget.Value;
20.         volumeSettings.m_Profile.TryGet<DepthOfField>(out depthOfField);
21.         apertureValueAtEnable = depthOfField.aperture.value;
22.  
23.         if (overrideAperture > 0)
24.             AdjustAperture(overrideAperture);
25.     }
26.  
27.     private void OnDisable()
28.     {
29.         AdjustAperture(apertureValueAtEnable);
30.     }
31.  
32.     public void AdjustAperture(float apature)
33.     {
34.         depthOfField.aperture.value = apature;
35.     }
36. }
37.  
38.  

 

I didn't notice that at the time I recorded the video. I double checked, whatever caused that error isn't happening anymore. Yet my non-updating aperture issue is unchanged.

 

@antoinecharton, could this problem have something to do with the fact that two Cinemachine cameras are using the same post processing global volume? I have a follow cam, and a seperate cam that is enabled for special events - but even with that camera disabled the aperture still won't adjust via my above code.

 

I've followed up on that thread, without any response. Please forgive me if I'm not following forum etiquette, but I'd like to ask again for some help on this issue.

 

ooooooh, this could be a way to do what I'm considering. Thank you.
