Thread: Editing MGFX files

    Default Editing MGFX files

    Hi all,

    Just checking if anybody here can help me edit .mgfx files that Open Rails uses nowadays.

    Before, there used to be .fx shader files in the Open Rails content folder but now those files are with the .mgfx extension. I used to edit the .fx files through text editors to tweak the graphics a little but not sure how to open .mgfx files as text editors like VS Code, Notepad etc. can't open them.

    Thanks for any help!

    Thank you!

    Okay so it looks like the only option is to edit through a complicated process that involves downloading the source code or just use an older version that has .fx files. Don't have to be this hard. Just wanted to change the fog and sun parameters
