Why are my scene's lighting and post process settings different depending on the computer?
I built a beautiful ArchViz scene at home that features bright and soft sunlight. To bring it to the office and share it with my coworkers (who are new to UE4), I zipped up the whole project directory and uploaded it to Google Drive. At work, I downloaded and extracted the files and fired up a fresh install of Unreal Engine.
The scene is very dark, the auto exposure and eye adaptation are not working at all, the lightmap resolution has been reduced by at least an order of magnitude (there are shadow bleeds and new splotches), and screen space reflections are totally absent. I've tried opening it in both the regular 4.4 engine as well as the source code version. I've re-downloaded and re-extracted the files to multiple locations. I packaged the game to HTML5 and it maintained all the same problems, although I expected errors regardless due to limitations. Tweaking the eye adaptation settings in the post-process volume does nothing for my lighting.
The worst part is: drum roll It works completely fine on my coworker's computer. Everything is perfect, even though it is the same downloaded file.
The .exe of the same scene that I built from home runs just fine on my computer, so it can't be a hardware issue, right? I'm so confused. Please help!
Hey StephaBon -
Can you go under Quick Settings >> Engine Scalability Settings >> Make sure that everything is set to EPIC? If it is go under Show >> Post Processing and ensure that your settings are checked true.

Solved it! Because no one answered for a day, I had posted in the Forums, where Tim Hobson realized what was wrong. (https://forums.unrealengine.com/showthread.php?41628-Eye-Adaptation-and-Screen-Space-Reflections-not-working-on-my-computer)
My work computer has a slightly older graphics card, and I didn't realize that Unreal Engine modified it's graphical settings based on how much your computer could theoretically handle. Under the quick settings, I had to change the Engine Scalability settings back to high. It was only previewing what would be available on weaker platforms.
