At the start of white mesa, console is complaining about tons of files that are missing. I've got no speech and some objects are just errors. Do you know about this?
I already tried reinstalling the game and resubbing to the mod.

Try subbing to the resource pack: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=822421143

If you haven't played it, I suggest you check out the prequel first:

IF you're loading a saved game, you need to put in
snd_restart
in the console once and then reload the loaded game.

This is due the sounds doesn't have a cache file for them since bms lacks the command to generate it.

Also are you playing on normal version or the beta version of Black Mesa?

Thre snd_restart fixed it, thanks!
All objects objects are now rendering properly as well. I'm using the normal release. Maybe something on my end just consistently screwed up. Anyways, thanks again, it's a great mod :)
