# PostProcessing Editing

### GMUIManager - Use ONE post process rather than two?

{% hint style="info" %}
As you can see below the "**GasMaskVisorUI**" method is setting the VisorImage, the EnableVignette and the State of either GasPostProcess or the original. \
\
You can comment out those lines if you didn't want to change the state and just use one post processing effect.
{% endhint %}

```csharp
 public void GasMaskVisorUI(bool on)
        {
            visorImageOverlay.SetActive(on);
            EnableVignette(on);
            if (on)
            {
                SwapPostProcessingProfile(PostProcessState.GasPostProcess);
            }
            else
            {
                SwapPostProcessingProfile(PostProcessState.OriginalPostProcess);
            }
        }
```

```
public void EnableVignette(bool on)
        {
            _vignette.active = on;
        }
```

Edit the Awake method below by changing the "*gasMaskProfile" to* "*originalProfile" and you can use this instead to access the "*\_vignette" as per the EnableVignette method above. 

```csharp
        [SerializeField] private PostProcessVolume _postProcessingVolume = null;
        [SerializeField] private PostProcessProfile _originalProfile = null;
        [SerializeField] private PostProcessProfile _gasMaskProfile = null;
        private Vignette _vignette;
        private DepthOfField _dof;
        
        private void Awake()
        {c
            _gasMaskProfile.TryGetSettings(out _vignette);
            _gasMaskProfile.TryGetSettings(out _dof);
        }
```
