I do not know what you are advising they do to be honest, I really don’t - they have explained it well enough.

Is this now answered?

23

No not yet. I am beginner in C++, so I have to figure out how. I appreciate the answers but I would appreciate code examples too.

I am still looking for a solution to load a level from a .pak file.

But even getting to this point, this documentation helped me:

(Do not use their video in YouTube, that tutorial has few vital mistakes)

Finally solved my issue.
The answer is no you cannot mount and use .pak in editor.
The error will be: LogChunkDownloader: Error: Unable to mount chunk x (no FCoreDelegates::MountPak bound)

I added the scene that I want to mount in the product as a plugin, to be used for the development.

While in the built version, everything works fine and .pak is mounted without errors.

Hi Roadified,

I am trying to open a map level from a pak file using blueprints, but not successful, can you share me some tutorials.

When running Unreal Editor, run it with the ‘-UsePaks -EditorDomain’ command line parameter.
And turn on ‘Allow Cooked Content In The Editor’ in the ‘Engine - Cooker’ section of ‘Project Settings’.
In my case, I can read ‘.uasset’ from ‘.Pak’, but I’m not sure ‘.map’ does.
ex) UnrealEditor.exe [YourProject].uproject -UsePaks -EditorDomain
