How do i get rid of the glowing effects that exist by default?

how do i get rid of this glowing effect?i wanna make the scene completely dark

It’s the fog I’m afraid…

Are you referring to in the background with the fog? or farther in the foreground with the glowing green effect that looks as if its because of the road or maybe its a barrier you put into the game? Does it show up when you try to play the game itself? If not it may just be showing up this way due to the developer settings in the engine.

i’m talking about the glow in the sky and I literally just deleted any lights that existed by default even the sky sphere and it still not completely dark

Exponential Height Fog & Also Check Post Process Volume

Also bloom in post process volume will do some of that, but mainly you need the sky to be dark.

Make the fog color black.
