Materials addon - Where'd the downloads go?

Hey, does anyone by chance have a working download link for the source material addons? (Where it updates your material list with the rest of the materials from source) Or could re-upload, I’ve searched everywhere and still no luck finding the pack.

There used to be like 5 of them last year… :c

If you’re talking about the original source materials, like from hl2, there isn’t a download. Although there is .
