Help with fading material out over distance

Honestly the fog just doesn’t look anything like that for me, as soon as I add the HDRI cubemap the fog essentially disappears, and when I adjust settings you can see it vaguely affecting the HDRI sky in my scene but nothing else - I’ve tried playing with all the settings and I can’t seem to get any fog to appear.

Nevermind, kept messing with settings and realised I had to bring it quite high in my scene to get it to work, thanks man!
