Source games use the scripts\ChapterBackgrounds.txt file to load background maps. However, this doesn't work in TF2. No matter what you do to it, the game will only load static VTF backgrounds. The only way to load background maps in TF2 is the map_background console command.
ok but has anyone asked valve to add these but i have another idea, it scans your pc (or looks at your potions menu to decide) and only uses menu backgrounds that your pc can cope with (or you decide)
btw the guy that voted they'll ask valve what did valve say
