Disable Eye Adaptation (AKA Auto Exposure) v1.0
Simple INI tweak to disable Unreal’s eye adaptation/auto exposure that changes the exposure levels w hen you look at different lights.
DISCLAIMER
It appears this fix isn’t as reliable as I initially thought… So you’re welcome to try it buy your mileage may vary. After initially applying it I had a good hour or so where it was working great. Then I stopped playing and came back and it wasn’t working anymore. As far as I know there was no update. Others have reported blown out lights like they are on the surface of the sun, others say it doesn’t work, while some say it works great… so I have no idea whats going on. I’ll continue tinkering but I’m tempted to take this down so that people don’t complain when it doesn’t work at this point…
Unreal has eye adaptation/auto exposure on by default and most games include it. This means that when you look at a light, it will dim the overall brightness of your screen, and when you move away from looking at it it will brighten it. This is meant to simulate the effect of human pupils dilating when you look at lights – but IMO its very irritating and games tend to be a lot better with it OFF. If you agree – then you can disable it very easily with a single line in the engine.ini
To find your engine.ini (or create it if you don’t have one)…
DEFAULT LOCATIONS
WINDOWS:
Go to C:\Users\[USERNAME]\AppData\Local\Stalker2\Saved\Config\Windows
LINUX:
(note: the 1643320 is the AppID for the standard edition. I’m not sure if this might be different for the other versions – you may need to check the appid for your version if you don’t see 1643320 there)
/home/.steam/steam/steamapps/compatdata/1643320/pfx/drive_c/users/steamuser/AppData/Local/Stalker2/Saved/Config/Windows
In this folder should be a bunch of INI files. Look for Engine.ini. If you do not have one – create it.
Find the section of the INI labelled [SystemSettings]. Again – if you do not have a section like this, create it at the end of the file.
Add the line:
r.EyeAdaptationQuality=0
If you created a new Engine.ini file, your entire file should now look like this:
[SystemSettings]
r.EyeAdaptationQuality=0
Save this file and you’re good to go!
