I read up more about the default for pure and its "from steam" so you just have to add the folders you want to allow, like mods. I just redid my whitelist because of all this lol.

Code:
materials\...                     from_steam
models\...                        from_steam
models\player\...                 allow_from_disk
materials\models\player\...       allow_from_disk
materials\effects\...             allow_from_disk
materials\hud\...                 allow_from_disk
materials\temp\...                allow_from_disk
materials\vgui\logos\...          allow_from_disk
materials\vgui\logos\ui\...       allow_from_disk
Basically the default settings that come with the white list.
