HDRP, Lighting Brighter Standalone Build vs Editor

Questions & Answers
1

I’m having a very strange issue with my project using HDRP. The problem is that the game gets significantly brighter when running the standalone player compared to in the editor as shown below:
Editor
Standalone

I have no idea what is causing this. I am not using any baked lighting in my game either.
Here are my settings of Post Processing:
Sky and Fog
and
Scene
Does anyone have any ideas as to what the problem could be?
Maybe I have something miss-configured.

The first image doesn’t have ambient lighting applied, whilst the second one does. Regardless of whether or not you are using lightmaps, ambient lighting still needs to be baked initially to show up. If you want the image to look like the second, run a quick bake in the inspector and the lighting should update. If you want it to look more like the first, you can set the ambient lighting intensity to 0 in the lighting settings.
