Inside Unreal: ChunkDownloader Explained

Hi I was working on this fantastic tutorial. I was able to get basics working but I am running into few issues.

  1. In the demo after the package all chunks are going to packaged folder. @Michael is deleting those chunks in demo video before running chuck downloader. In the mobile package, all chunks are going to apk or ipa file which I am unable to delete. How to tell the engine not to include downloadable chunks in the package so paks can be shipped from the server? For example: chuck0 to keep is package but chunk1001 and chunk1002 from server.
  2. For updating chunks or already download content, do I need to increment or update the build-id to make it a chunk downloader to detect new changes and redownload and mount new chunks or something more than that?
