Material hacks are not working.

Hello.
I've downloaded material hacks, placed them in "D:\Steam\steamapps\---\counter-strike source\cstrike\materials" also tried to put them in common, nothing works. They are copied, but no wallhack. It used to work before, but now it's not working.

Copy the Material hack and go into Steam/steamapps/common/counter strike source/cstrike/custom and place the material hack there. And If you dont have the custom folder, Make it.

Yes that's the solution,
