As the title says. I've modified two files a little bit, to remove the chromatic aberration filter material. But it also removes that yellow, warm, saturated color feel. It's because of a file named : postprocess__c___o_.mat . Which i bet it can be found in the encrypted inaccessible rpack files. It is a simple filter. When used by the game, it gives that yellow color and also chromatic aberration all over the screen.

I took advantage of the new feature added to the game, Post Processing filters (which allows you to change to various color filters) and made a small enable / disable of chromatic aberration. Make sure to create a BACKUP of the file you intend to replace. Instructions below :

1. Download
2. Extract the file and copy it
3. Go to your Dying Light install folder, then open folder DW
4. In this DW folder, paste the Data3.pak file you just extracted. If prompted, click OK to replace.
5. You are done!

Now you can start your game and by default the chromatic aberration filter will be removed. IF you want that filter back, then go to Options>Game and the option called Post Processing, you can simply select Black & White filter.Now chromatic aberration along with the yellow filter will be back.It's default mode basically without having to manually delete it. Remember this is a modification, not official supported feature.
