Missing map textures everywhere

I’ve been getting a serious problem recently, whereby most stock textures from HL2 are missing on every map, from standard Gmod, to CSS, to HL2 and TF2. and I haven’t got a clue whats causing it

not working. Half Life 2 doesn’t convert to steampipe despite opting in and out. there’s no pop up to give me the option

Opt in, start up, exit, restart Steam, and start up again. If it still doesn’t work after restarting Steam, verify the files.

Just stay opted in

Nothing seems to work. I opted in and restarted, and even verified the files. still getting an ocean of black and purple

Check your common folder, is Half-Life 2 there?

Fixed it. had to verify the files of all steampipe games, just on a hunch. It’s all better now.

thanks for the advice, never would have thought of verifying
