Exponential Height Fog Not Appearing

So I’m new to using Unreal Engine. I’ve never had to work in it before, but my class is requiring it and my teacher hasn’t given me responses. The scene I’ve put together uses the free Infinity Blade assets from the Epic Store. I’ve built my scene and now I’m supposed to light it. I dropped Exponential Height Fog into my scene but nothing happened. When I drop the height fog into a test scene it appears immediately so I don’t know why nothing is happening. My scene is also super bright, don’t know if that could be causing problems too. If someone could give me some possible answers in newbie speak that would be great. I can provide screen shots of whatever you might need to see. Any help would be appreciated.

Sounds like brightness might be the problem. Did you leave directional light and skylight on defaults?
