Can anyone help find the AES key for Radiohead's Exhibition? (free on epic)

@Gerlamp: Read this post first: viewtopic.php?f=9&t=1005&start=1940#p67581
But you can probably edit only paks contents that way (i.e. configs and probably some localization things) and some assets are stored in cpk packages, which are criware containers with their own tools and methods for packing. Can't help you any further, because as of now I didn't see any mods aimed for iostore format from latest UE4 versions (ucas/utoc packages).

@edinky: Check my signature.

Script for extracting audio from Gears 4 added to sound extraction bundle, available in my base post. It can be used on uasset files (in case for audio they're stored in Game/WwiseAudio/UAssets), which can be extracted with umodel via "save packages" option. The script has alternative option to extract all wem to a single folder, which may be useful for batch operations. Not sure about wwise ids though, but they seem correct.

Hi there!

I'm trying to access a .pak for Final Fantasy First Soldier which worked previously with the unreal_tournament_4_0.4.25b.bms script, but after the latest game update i'm getting the following error:

QuickBMS.exe

Code: Select all

Error: the requested amount of bytes to allocate is negative (0x84f674d1)

Last script line before the error or that produced the error:

Hello.
Does anyone tried to unpack latest "Dead By Daylight" versions?
They don't seem to be encrypted so it extracts fine with no errors, but the folder structure is all messed up. What I mean by that is some things will be extracted properly (say, Dead by daylight -> Content -> Characters -> Campers -> Dwight), but other things will be extracted straight into the core folder (so there will be a "David" folder, while it should be Dead by Daylight -> Content -> Characters -> Campers -> David).
Is it something with the script, DbD-specific or a general .pak extension issue? Is there some way I can fix that?
Thanks in advance.

@gRimmDesu: I suppose they've simply updated the key. You can check my signature for topic with most recent keys and key requests.

@Argemon: Use respective script from post in my signature (depends on the UE4 version, used by the current game version), it should produce paths with mount points appended - it's around the same what you're asking for.

There is no script for Dead by Daylight and I'm using the Unreal Tournament script. Though I haven't noticed there's actually 2 versions. I'm currently running the latest (I think?) version of that script, so gonna try the 4.25 (which is the version the game is running on). Thanks.

I'm so sorry I didn't realise it was just a key issue! Seriously appreciate your help thank you so much!!

thank you so much

@Argemon: Yes, there is no specific script for DBD. And you're right, if the game is built with 4.25 engine, you need to use 4.25 script, because 4.27 one is compatible only with 4.26/27/UE5 games, like explained in my base post.

@TheOne2022: For GTA3 DE packages you need to use 4.27 script from my base post. And you can't open extracted cooked assets in unreal editor directly, you need to convert or parse them first. You can try umodel (you'll need specific build for this game) or fmodel, or any other other general parsing tool for UE4 assets. And there are plenty of GTA3 modding communities over internet, it's better to ask such questions there.

Hey guys.
I'm trying to extract a "RioV4-WindowsNoEditor.pak" file from a game made in Unreal, but I'm having problem because the file is 12GB in size. How do I extract a file from this ?

[spiritovod]

@Telzin2k: If it's from Raised in Oblivion, you need to use 4.27 script, available in the post from my signature, with quickbms_4gb_files version of quickbms to extract the package.

[XxDarkus101Xx]

hey, is there any bms script and AES key for Back 4 Blood yet? I'm trying to unpack the pak files and I used the original script from cs and that didnt work? I want to see if I can possibly modify some things.

Hello everyone.
Áƒ * žùÿÿÿ in the header of .uasset files, what does it mean?

When editing these files, the game will not start.
What should I do? Found nothing!

[spiritovod]

@Morty888: I also couldn't find any sample or game name in your post, which would be helpful for determining the issue.

[spiritovod]

@Morty888: It was a normal uasset, until you've improperly edited it. Such things can't be edited manually, because by adding a single byte you're triggering changes in offsets, import/export tables and so on. I can only suggest to use tools for parsing and editing uassets like Asset Editor or UAssetGUI - they might work, but it depends on the game (some games has additional checks for certain data). In this particular case the game in question is Mortal Kombat Mobile, so some data may have server-side checks as well.

And please note that this topic is for general questions about UE4 packages and related script. If you have questions about contents of already extracted assets, you can ask them in other forum sections or other places, like modding communities.

[XxDarkus101Xx]

I have the aes key for back 4 Blood (december update) but there is no point to post it since there is absolutely no tool to unpack it with, so until then Ill just keep it
