I had the BuildID incorrect which was causing an error with what UE expected vs what we were giving it, the explanation in the docs isn’t great so I ended up fixing it after debugging for a while.
So as a real quick tutorial because the video and documentation Epic have don’t seem to explain everything, turns out that you need to order your Pak files on a remote/cloud server in a specific format and then reference them that way.
The Structure should begin with your ContentBuildID.txt file and a folder, the ContentBuildID text file should have the name of the folder in it.
Inside your Content Folder you need the BuildManifest-(PlatformYou’reTargeting).txt and another folder that will hold the Pak files.
The BuildManifest-Windows (etc) will have an entry count, build ID and then a list of all of the chunks.
Num Entries is the amount of Pak files you are referencing
BuildID is the ContentBuildID or the directory these files are located in
pakchunk is broken down into 5 parts The Pak file name
The size in bytes (right click, properties on the file itself and take the bytes part of Size)
The version as a string value
The ID of the chunk
The location of the chunk from this directory
