Css and css maps for gmod

This post is really useful, although if you download the CSS textures and still have missing textures in servers that you play on, then: Make sure you have all the correct add-ons downloaded and installed for the server, and if they're still missing, download a few more content packs from here: http://kajar9.wixsite.com/cscheater2/downloads

If you're missing textures in Gmod, you won't need to download the CSS maps, or at least from my experience. They're just for you to download if you want to play Prop Hunt on de_office or something similar, even then it's likely that servers have some kind of modded map that allows you to download it from the Steam workshop.
