I've been helping a user not from here make a map for a gamemode not yet released for other servers (Parkour Fortress CTF). I was slow in getting playtesters, however, and by the time one of them pointed out how cramped the map was the main layout was mostly finished. While upscaling x/y by 25% satisfied the playtester, it also left lots of brushes with half-units (despite a vast majority being divisible by 16). Is there a better way of resizing that helps avoid half-units, or does the layout need to be remade to be less cramped? Thank you for your time.
