Help please can not install HL2beta texture

Help please can not install HL2beta texture. I translated them into the folder with the materials th at I downloaded here, then I used a .fgd file with a beta anon, I did not try different methods but not what did not work (I used VHE of the garry folder Mod)
map c17_04_41

use the material editor in Hammer to find out the name of the texture, then search in your materials folder for the texture, if its not there it could be one of the missing textures and you’ll have to search the FP threads to see if someone found it and posted a download link, if it is in the materials folder take a look at the .vmt to find out why its not showing in hammer
