Summary

I am unable to get fog working in the game view. I have only seen it working in the editor.

Steps to Reproduce

1. Opened up Island Settings turned up Fog Thickness to 80% and changed Fog Colour to a blue colour. Nothing happned in game or in the editor.
2. Added Day Sequence Device to Outliner. Turned on Fog. Left everything default except for the colour. I added a blue/white colour. Fog was visible in the editor but not in the game.
3. Added Exponential Height Fog. First left everything default except for colour, but i noticed no change in the editor or the game. Turned Density and Height fall off up. Only when i was moving around in the editor did i see the fog but then it would quickly disappear. Never did i see it in the game with Exponential Height Map tuned on.

Expected Result

I expected to see the fog in the game with all three of the options i tried. Never once did i see it in the game.

Observed Result

I did see the fog in the editor when using the Day Sequence device, but not in the game.

Platform(s)

I am developing on a Windows 11 PC, with a RTX3070 GPU and a i9 12900K CPU.
I have tried the game view on my PC and my PS4.

Additional Notes

I cant seem to upload an image here. I have added a link to the original post which does have an image showing the game view and the editor view side by side comparison.

No fog in game

I am trying to get fog working in my game. From what i could find there is three areas to control the fog; Island Settings, Day Sequence Device, or Exponential Height Fog. I have changed the settings on all of the above mentioned. As you can see in my image i posted i have fog in the UEFN editor but not in the game. I have searched and followed many example but come to the same result sometimes i see it in the editor sometime i don’t but i never see the fog in the game. [image]

In the engine, I see the Exponential Height Fog.

The exponential height fog only works on Engine Scalability high and Epic.
Then I change the graphics settings in the engine to Scalability: Medium. Then back to High. The fog does not return. I have to save the project and the fog shows back up.

In the game editor, there is no fog. I have to end game, change the graphics settings, then restart new game.

The fog only shows in game when settings are set to… Native quality. Not the quality setting. I have a level that specifically relies on the lighting with this fog I created combined with the directional lights like sun rays. I really do not want players to see the map without the fog.

O well. Better luck next time.
