Menu wallpaper & loading screen

I installed a custom background but I wish to get the default back. What do I delete?

First, download the custom background and search for the files, then delete it. After your background is the default , you can’t delete the default because its in .gcf and if gmod not found a custom background , its make the default for background.

Problem is, I forgot the name.

it should just be called “background01.vtf” or something
