Since I lost the old postfx files and for some reason the ones on here didn't work anymore, I decided to make a new postfx preset. Keep in mind this preset was made with Brother_Dave's graphics mod installed, so it will not look like the screenshots unless you have that mod installed. Credit to Brother_Dave for his graphics mod used in the screenshots. Unfortunately it won't let me link his mod without it being marked as spam for some reason. How to install: You may have to enable the postfx settings first. To do this you go into Options > User Interface, then click the check mark next to enable advanced functions, this will make a postfx button appear in the graphics options. Drop the RealFX.postfxpreset.cs into Documents > BeamNG.drive > Settings Once in game, go to Options > PostFX > Load Preset, a popup window will appear then navigate to and click on the cs file you put in the settings folder.
You have to go into Options > User Interface and click the check mark next to enable advanced functions, that will make the postfx button appear in the graphics options. Then from there you click the postfx button, click on load preset and it should open a window. Then just click on the postfx preset that you put in the settings folder. Sorry about that, guess I should explain how to do it in the post.
