I got a problem here with a map I'm working on.
I use the breencasts that you find the C17 map.
In HL2, the sound works and everything well. The screen is aligned, clear and correctly.
But when I open the same map, in Garry's Mod. It's totally messed up like this:

Anyone have any idea why it works perfectly in HL2, but messed up like this in Garry's Mod?
Thanks a lot!
