Sorry all of you guys for not responseding, i've been working very hard at work. Careful when deleting the file names, when deleting the wrong file you'll get a bad error for your weapon(s).
Go to 'C:/Program Files/Steam/steamapps/common/Counter Strike Source/cstrike/materials/' and delete the folder called 'w_models' and go to 'C:/Program Files/Steam/steamapps/common/Counter Strike Source/cstrike/models/' and delete the files the have a w in front of it like so (an example of a file that has a w in front of it 'w_weaponname.mdl' of course it's not just this type of file). It will work as long as you have another folder in the custom folder. Also you can change the 'my_custom_folder' to whatever you want like you can just say 'skins' and you just put the files in their. Sounds - In C:/Program Files/Steam/steamapps/common/Counter Strike Source/cstrike/custom/my_custom_folder/sounds/ These are the main four files your going to get for weapon skins.Scripts - In C:/Program Files/Steam/steamapps/common/Counter Strike Source/cstrike/custom/my_custom_folder/scripts/.Models - In C:/Program Files/Steam/steamapps/common/Counter Strike Source/cstrike/custom/my_custom_folder/models/.Materials - In C:/Program Files/Steam/steamapps/common/Counter Strike Source/cstrike/custom/my_custom_folder/materials/.Well since the update that Valve released, the files are now part true and this is where you NEED TO PAY CLOSE ATTENTION to Steps 4 & 5.
