I have installed Team Fortress, but the viewmodels are still messing up.
How can I fix this?

And also: Is EP2 Required for the “refraction” effect, because I do not have it installed but I do own it.
I have Garry’s mod map that uses this effect, but it looks like a bunch of blue-spiky shells.
It says you need Ep2 and the pictures show refraction. Is Ep2 where the refraction and water texture come from?
