Can't get the VGUI Build Mode Editor (CTRL+ALT+SHIFT+B) to display anything other than [no resource file associated with dialog.] I can edit the old-looking HUD elements of the console and the "create a server" UI but nothing else.
Been editing hud elements manually forever to add extra buttons to this 2012 main menu edit and I just learned about this, but there's no instructions on how to use it.
Normally I wouldn't ask for help about something so simple but I can't seem to find documentation for this thing anywhere. Even this TF2 HUD creation guide doesn't include this thing. There's no way that every single HUD creator just uses trial and error and runs mat_antialias hundreds of times to check if each value looks good, right? ...Right?
