Lighting completely changed after working on another project

I am facing a very strange problem, I was working on a scene and set up its light and it was working fine, then i gave this scene to my colleague and on his pc the light is completely different after light built even when we use the same engine version. what is even weirder is that i copied the scene back from his pc to my pc and the light stayed bad and not only that my old project that was fine has the same lighting problem. what is happening here? somehow opening the project from his pc modified some engine settings?


…it’s not just exposure setting? …to me it just looks brighter nothing else but maybe I’m missing something! :wink:
