If you are experiencing problems with your Garry's mod that make your game maps purple with black squares (Black with purple squares if you want to be different) or all your weapons are errors you can fix this with one the two solutions:
1) You have to download the CS:S textures, These can be found in the link below. (The file is called CSS.rar ) The folder inside CSS.rar should be extracted into the Addons folder (Steam/SteamApps/(Username)/Garrysmod/Garrysmod/Addons.)
Once you have downloaded the CSS.rar and you have put the CSS content addon into the Addons folder, copy the materials from the CSS content addon and paste it in Steam/SteamApps/(username)/Garrysmod/Garrysmod and merge it with the existing materials folder.
Replace all the files when it asks you.
Once this is completed you should have all the textures for CS:S installed.
2) Buy Counter Strike: Source....Gmod13 fix
I assume you already downloaded the textures to open your
C:\Program Files (x86)\Steam\steamapps\<name>\garrysmod\garrysmod\
and drag only these folders: http://i.imgur.com/0J0dG.jpg
drag them into your gmod folder and let the files merge.http://i.imgur.com/6JoWq.jpg
If it asks to replace anything just skip all of them. then your donehttp://i.imgur.com/pJ8WN.jpgLinks:http://www.garrysmod.org/downloads/?a=view&id=129926Notes:
- You will need 7zip or WinRar to use the CSS.rar
- If you have already done my Maps download, The names of the two folder you have to extract will be the same, just merge the two folders and it will still work.
