Unable to create backend graph using the default graph settings

[freakshow0]

No matter what i do, absolutely nothing works. i can put any commands i want into the program, i can put any files i want in (the pak, the sig, both, doesnt matter), i can put BaseEngine.ini anywhere i want (i heard it was a solution). it just says "Unable to create backend graph using the default graph settings" and does absolutely nothing.

My command was (unrealpak.exe dir) (pak dir) -crytokeys=Crypto.json Heres my log LogInit: Display: Loading text-based GConfig....

Hi @freakshow0 ! Got the same error when tries to pack file from folder:

So it says that no default configuration was found in file:

../../../Engine/Programs/UnrealPak/Saved/Config/Windows/Engine.ini

Moved the program to the deep folder to have ability to navigate to ../../../ for example I moved UnrealPakTool to the folder: C:\Programs\UnrealPakTool\UnrealPakTool

Also created the Engine.ini file in the C:/Engine/Programs/UnrealPak/Saved/Config/Windows/Engine.ini with the following content:

[DerivedDataBackendGraph]
Root=(Type=KeyLength, Length=120, Inner=AsyncPut)
AsyncPut=(Type=AsyncPut, Inner=Hierarchy)
Hierarchy=(Type=Hierarchical, Inner=Boot, Inner=Pak, Inner=EnginePak, Inner=Local, Inner=Shared)
Local=(Type=FileSystem, ReadOnly=false, Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true, UnusedFileAge=34, FoldersToClean=-1, PromptIfMissing=true, Path=%ENGINEDIR%DerivedDataCache, EnvPathOverride=UE-LocalDataCachePath, EditorOverrideSetting=LocalDerivedDataCache)

and ran the command again

.pak file was created successfully, but didn't check it in the game yet.

@timaxapa

my .pak file is created when i did that but with 0 size, do know what can i do? because the error still happens and it generates the file but with 0 size

yo you find how to fix that? bc i tried like 40 minutes, but nothing helps

The same thing, a pak of 0 bytes is created.

I was having the same problem. You have to do what timaxapa said to do. It's looking for a file that doesn't exist, so just create that file. Create folders so that it looks like C:/Engine/Programs/UnrealPak/Saved/Config/Windows/ Create a txt file in the last Windows folder and rename it to Engine.ini Now copy/paste all the crap timaxapa said to paste in there. That's it. It worked for me.
