When I hit play the light changes for the worse

I put exponential height fog and was changing the colors on it to match the scene and right when I got it perfect I hit play to test it out in game and it changed all of the colors on me.

Any ideas to what could be causing this?

It looks like the camera in your character is applying its own post process settings. Make sure to place a post process volume in your scene and make it unbound. Tune it for the scene to look the way you want, that way the character camera wont override it.

where did the grass go? are you streaming levels? if yes make sure they’re always loaded
other than that it may be the post process volume
