Change ChromaticAberration (Cinemachine's) via script

Unity Engine

Hello All,

I’m struggling a bit on this one. I have a cinemachine virtual camera with Volume Settings extension and a chromatic aberration override.

I am just trying to change via code the intensity of the chromatic aberration but can’t seem to be able to find anywhere how to access it.

I can see with

foreach (UnityEngine.Rendering.VolumeComponent volumeComponent in volumeSettings.m_Profile.components) {
    Debug.Log(volumeComponent.name);
}

That a component with name “ChromaticAberration” exist. I also think that the class I want to use is
UnityEngine.Rendering.HighDefinition.ChromaticAberration

How can I now convert the VolumeComponent into the ChromaticAberration so I can change its intensity?

Thanks

Is there a reason why the chromatic aberration effect is attached to the vcam’s volume? Can you instead just make a global volume with only that effect and adjust the volume’s weight? That would be the easiest approach.

Thank you very much for your reply. I am using Cinemachine and HDRP, I thought that in this case the global volume does not work. If I try to set up a post processing layer and volume I don’t see any change in the game view.

Is there a way to use the post processing global volume with Cinemachine and HDRP? If not, is there a way to acces the components in the vcam’s volume?

I found a way to do it:

using UnityEngine;
using UnityEngine.Rendering;
using UnityEngine.Rendering.HighDefinition;


public class PostProcessingManager : MonoBehaviour
{

    public Cinemachine.PostFX.CinemachineVolumeSettings volumeSettings;

    private LensDistortion lensDistortion;
    private ChromaticAberration chromaticAberration;

    void Start()
    {

        foreach (VolumeComponent volumeComponent in volumeSettings.m_Profile.components) {
            if (volumeComponent.name == "LensDistortion") lensDistortion = volumeComponent as LensDistortion;
            if (volumeComponent.name == "ChromaticAberration") chromaticAberration = volumeComponent as ChromaticAberration;
        }
      
    }

    // Update is called once per frame
    void Update()
    {

        if (Input.GetKeyDown(KeyCode.M)) {
            if (chromaticAberration) {
                chromaticAberration.intensity.value = 1f;
                chromaticAberration.intensity.overrideState = true;
            }
        }
        if (Input.GetKeyDown(KeyCode.N)) {
            if (chromaticAberration) {
                chromaticAberration.intensity.value = 0f;
                chromaticAberration.intensity.overrideState = true;
            }
        }

    }

}
