Hi, I am new to Unreal Engine and currently checking out few tutorials. The issue is when I add Exponential Height Fog in to the scene there is no visible effect at all. - Before adding fog: ![Screenshot (10)](https://d3kjluh73b9h9o.cloudfront.net/original/3X/9/d/9d5d52b2231ece13d134ac27074d8bf7abe225cc.jpeg) - After: ![Screenshot (9)](https://d3kjluh73b9h9o.cloudfront.net/original/3X/8/1/810d52fb6204a073671846b1e34bcba9a542421d.jpeg) Is this a common issue? if not what am I doing wrong here? ---

Thanks so much!!! It’s worth noting that Alt+F will also affect the visibility of the built-in fog in the Sky Atmosphere actor, even if you do NOT have an Exponential Height Fog actor. ---

Hi, i still have the same problem. I only created a standard vr world and put in the exponential high fog next to the other 3 lights, but the black part does not go away. I tried all your solutions already. Hope you have an idea.

Thats probably because you dont have a SkySphereBlueprint added to your level.
