Did you specify that you wanted it to be a multi-part VPK?
They aren't embedded in the BSPs. Those sounds are in DLC2, you only hid the files from the base Portal 2 game.
Yeah, you're right. But I know whats the problem. Some soundfiles are not localised, the ones in dlc2 folder. I wasn't able to remove these so far as I did with the main folder as some texture items were missing when browsing the workshop file list. Doesn't look nice, only thing I could force is to stop the file from beeing played at all. So I've copied the vpks back for now. If I'd new in which vpk the sound files would be I could delete these without compromising the menue textures. Funny that it did't care for the files which I had extracted before and copied to the disc.
wohoooo! packing the dlc2 folder with vpk.exe worked well! I've renamed the cave folder and now it's fine and doesn't interfer! Thanks for the help FelixGriffin
No problem. Are you looking to localize those sound files as well, or is removing them the end goal?
