So, does anyone have any information regarding how soundbanks should be set up in Wwise for Attila? I doubt the old Rome 2 template will work, for obvious reasons, but I haven't tried it yet. All we need are names for the appropriate playlists, which could be discovered from even having the individual track names of the .wem files, but since they're exported as a Wwise project it all comes out as numbers instead of what they're called on the template (having a single battle_roman.wem track name, for example, would reveal what the name of the playlist should be).
I've tried to reverse engineer the soundbank names using the music.pack files from Attila, which pulls out the .bnk and .wem files exported from Wwise, but there's no way to "put them back in" as a new project or convert them to any sort of file that Wwise will accept (it only seems to be able to open project files). Everything I found through Google regarding converting or opening .bnk and .wem files is out of date from the looks of things, with the one same specific guide on nearly every website that tells you to download a tool that by all accounts doesn't seem to exist anymore (called bnkextr.exe or something) from a Russian website that has changed domains. Getting any kind of straightforward information out of the bits and pieces out there is nearly impossible.
If there's a way to open the individual .bnk files from the music.pack file, we'd have our solution though.
