I’ve seen this effect in a lot of PS1 games (and some mobile/web games) where the skysphere/background is visible but there is still fog that completely obscures things that are distant from the camera.
Do you know how to achieve this effect in UE4?
Thanks in advance.
Edit:
Here is a video of a game that features this for reference:
