I have downloaded every texture for gmod (both css, both half life, left for dead 2 and team fortress 2). I have then put all the folders in the Gmod addons file but I still have missing textures and errors. Do the textures not appear for me because i havent bought the CSS on steam? Or are there more things for me to download, or maybe i just put them in the wrong folder

Thank you mate, much appreciated < 3
