Put "models" in the "materials folder"
Use notepad++ (if you don't have it its free just google it) go to pak01_dir.vpk
and find $baseTexture "models\infected\hunter/hunter_01" to $baseTexture "models\infected\hunter/hunter_02" and save
thats it have fun!! PS backup files just in case if u mess up on something
