no scopes on sniper rifle sweps

every sniper i download, whenever i equip it, it gives me some error and when i look down the scope, there is no view, only purple checkerboxes. the error says something like “missing file scene/scopeview”. whats wrong?

You are missing the scope texture.

well, i could guess that much, but what should i do?

Download it. What else?

how? its not a mod component, its a half-life 2/garrys mod component.

get it from the HL2 GCF file then.

probably css textures.

Yeah, I had to download CSS to get those to work.

oh. i guess ill just get cs then.
