# Unity3D: Sudden lighting change in a scene

Sorry if this is a duplicate question, but I have no idea what this would be considered.

Hello, I have recently been creating an FPS game, but while researching some things on the internet, the lighting changes within only one scene. I actually want to keep this change, but I am not sure what changed to make it look like this.

It unusually changed from this:

To this:

I want to keep the new one, but have this same lighting effect on a different scene, however, I am not sure what can cause this change. I have searched high and low for anything that could've changed, but I couldn't find anything. Any help is greatly appreciated. Thanks!

The way I fixed this is to go to the Lighting menu at Window > Lighting and configure the Lightmaps to Auto.
