So well all know the vanilla maps: upward, 2fort, badwater, ect. However where do i find the vmt file to edit. I see that there are altered versions of some of those maps, and I would love to practice altering made maps before being too serious of building from scratch. So is there any place I can find an editable file of maps that are in the game? Or are the files secure, and I would have to make a replica?
