I wanted to make the camera blur when health is low. I don’t know how and I need assistance.
My Unity version is 2019.4.21f1 LTS

If you’re using the Post processing stack V2 from the package manager, in a standard template project, then you can do this with a reference to the PostProcessVolume component. For example:

// Important: Reference to Volume component
using UnityEngine.Rendering.PostProcessing;

public class HealthEffect : MonoBehaviour
{
    public PostProcessVolume Volume;

    // Blur effect
    DepthOfField depthOfField;

    [Range(0, 100)] public float Health;

    void Start()
    {
        Volume.profile.TryGetSettings(out depthOfField);
    }

    void Update()
    {
        // Focus distance is affected by current health
        // Less health = greater distance to the point of focus
        //             = more blur
        depthOfField.focusDistance.value = 100f / Health;
    }
}

That’s one example. I’m sure you can build on this to affect other effects such as vignette, when on low health. @Gu3stBandit
