Downloading extra content

I’m trying to figure out how to download additional content. This is on iOS and Android but I figure the same solution applies to all the various platforms.

So far I’ve set up Primary Asset Labels by directory, but when I extract my IPA or OBB file it still just contains a single PAK file. How do you build it so that it builds each PAL into a different PAK file?

And second, how do you download the extra PAKs at runtime?

Cheers in advance.

I’m also looking for the exact same thing and found the same results. If you find anything please tell me!
