RenderSettings.Fog doesn't work in PC build

I have a following script attached to prefab which instantiates when stage is loaded:

	void Start () {
        RenderSettings.fog = true;
        RenderSettings.fogMode = FogMode.ExponentialSquared;
        RenderSettings.fogColor = new Color(0,0,0);
        RenderSettings.fogDensity = 0.05f;
    }

The script works fine in editor and I can see the fog, but in PC build nothing happens. What’s wrong?

Oh I just found this article talked about the fog problem that I had same issued like you and it worked!!

Just go to Graphics settings and change the Fog mode to Manual.
Hope this fix your problem as well.

Thanks
