@OLOCAT well this addons now is pretty useless because of "July 2025 Update", where Garry adds Counter-Strike: Source and some Half-Life: Episodes content in game, so you don't need to download mods or CSS to get rid off black and purple textures and ERROR's.

Maybe addons or maps that you play with not using CSS content, but another games assets (like Team Fortress 2 for example). Or you just didn't download additional addons for that addon you downloaded. So read description more carefully of addons you use, they may contain information about this.

The black and purple textures haven't been removed yet, they're still on my mods, please help.

this mod has changed my life in every way

this is the best addon ever, Kazuki, you outdone yourself, i know you just ported css content into gmod, but seriously dude, your awesome, you helped me so much, i love you bro :)
