Upload the big (and decrypted, ...steamless...) executable in case someone wants to check it.

Trying the script on the Street Fighter V Arcade Edition StreetFighterV_General.pak archive causes this error to appear.

I am using the latest version of QuickBMS and the Unreal 4 Engine script as well.

It does output two files and one folder before it gives that error.

Other game archives extract without an issue however.

@brendan19
Did you have the same error with older versions of quickbms and script?
Does it use an encryption key?

I'm newbie with QuickBMS. So I do not understand much yet.

I can't figure out how to edit the files. It ended up with a ton of 1kb .uasset files and then larger .uexp files with the same name. I did a ton of googling around, trying editors, trying everything I could and I just couldn't find out how to edit them. I found one person who had the same situation as me (1kb .uasset and then larger, matching title'd .uexp files), but I couldn't figure out a solution from the thread (nor do I remember where it is anymore, after googling around for many hours).

EDIT: I managed to get UE Viewer working, but how can I actually edit the files? I can export and view, but that only lets me view any images/textures. What if I want to change, say, some text in the game?

Any help would be great, thank you!

@peupuppy
Reimport mode works in a different way.
You must select the same script, input file (that now will be edited) and output folder (that now will act as input folder) that you selected during extraction, it's exactly the same process.
Everything is explained in section 3 of quickbms.txt and viewtopic.php?p=23032#p23032

No I haven't had an issue before. I've used QuickBMS before and the earlier iterations of the Unreal Engine 4 script to extract that package without any problems.

I'm assuming it uses the exact same decryption key as Street Fighter V as all of the other 68 "pakchunk##-WindowsNoEditor.pak" archives extract without a problem using the same key.

Can you upload the filecutted files of that archive?

Here's the sample for you

StreetFighterV_General

The archive itself is over 8GB in size so I know to use the quickbms_4gb_files.exe and not the standard quickbms executable.

Post subject:  Re: Unreal Engine 4 pak-file Unpacker / unreal_tournament_4.bms [UE4 global topic]

The beginning of the archive (whole 2Mb of the sample) is just zeroes.
I don't think any older version of the script or quickbms has ever worked on that specific archive.

Are you sure that archive is 100% correct? It may be corrupted.

*edit*
if you are really sure that the file is correct, modify filecutter.bms setting MEGABYTES to 10 and reuse it to generate bigger samples.

I thought this might come up after uploading the sample as the archive doesn't have data until 0x10700000 so I've cut from there instead.

New 10MB samples

I confirm that your file is corrupted

Yep it was. Fixed it up now and it's all good.

. Im wondering if you could help please?

I'm encountering problems extracting from the .pak from Dragonball FighterZ.

Im using quickbms_4gb_files.exe [0.8.3] with unreal_tournament_4.bms [0.4.14]. I've uploaded a screenshot of the error.

I also used the filecutter.bms on the .pak and uploaded the two files for you.

Thanks!

When prompted to select a password just press RETURN.

If it still gives an error then upload the big game executable.
