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

[GGA_Jeremiah]

I am looking to Mod the enemy stats in FF7 Intergrade on PC. I have been able to see models and textures with noesis and umodel but have been unable to get farther. I have tried using QuickBMS to look at the data but have so far been unsuccessful. Any help in this area would greatly be appreciated.

[spiritovod]

@GGA_Jeremiah: 4.25 script from my base post works fine with the game, you can find it via my signature. The key, required for extraction, is also available in separate topic, linked in the signature.

[DJ Normality]

Sorry I dont have the .exe to pull the key but if anyone knows the AES key for "Song of Horror" please post.

[spiritovod]

@DJ Normality: The game is not encrypted and using standard package format for the used UE version, so any compatible tools and 4.25 script should work fine with it.

[DJ Normality]

EDIT its working now Spirit i was trying to dump PS4 .pak. the PC one works.

Hello. When unpacking pak FNaF Security Breach, I get this error. With what it can be connected?

[spiritovod]

@DJ Normality: It's very possible that your PS4 package was corrupted upon extraction from pkg or from console. It happens, but for possible solutions it's better to ask at some PS4 communities.

@Dima Bilan: Oh, this thing again... I've updated base 4.25 script, available in the post from my signature, try it instead.

----------------------------------------------------

Both 4.25 and 4.27 scripts are updated to support extraction of large non-chunked uncompressed assets over 3GB. The core of this issue is explained in this post. In the same time, Sword and Fairy 7 specific script is removed from respective bundle, because base script can properly handle it now.

Ok I know I said this but for the heck of it just in case if anyone needs it, here's the AES key for Back 4 Blood

Thank you. I have now unpacked the .pak files but I don't know how to open the .uexp and umap files. I know umodel is more for visual changes to the game with models and stuff like that but I am interested in combat stat changes which would just be text changes.

[spiritovod]

@GGA_Jeremiah: In normal circumstances I would recommend fmodel for such things, but Intergrade is using custom unversioned properties, which are currently not supported anywhere, except for custom umodel build (partially). So if you don't know how to do it manually, I can only suggest to wait until proper support will be added to some public tools (like fmodel or those from this post) or take a look at original PS4 version of the game, which is using more or less default format for assets.

I will not delay. I'll tell you as it is.

Used standard Unreal Tournament 4 script on QuickBMS, when export reached 26.3 GB out of 79. Export fails with memory allocation problem.

I read it in the forums, it is necessary to update the script so that it exported it to the end. Because the file is too large. (who even sat in the wool studio management ?? They stuffed all the content (80 gigabytes) into 1 pak file.

AES key is available, no further problems are noticed.

Unreal Engine version: 4.25.0-SWG

I attach export logs:

Im need to export audio. And it seems to be hidden at the end of the pak file. And when exporting UE Viewer, it turns out to snatch a maximum of 30 sound files.

Hello @spiritovod I found some PUBGM Lite players modify some mini.obb.pak files !! They remove Weapon Recoil, modify Weapon Damage, and auto Aim from the weapon!! How did they do that underhand thing?? I'm always defeated by these players in the game !!
They also remove Grass and Smoke!!

[spiritovod]

@ikyAhmad: Those things can be modified in memory at runtime, so it has nothing to do with this topic or quickbms.

I moved your post here because this topic is all about UE4 and other users can check your problem.

Hello, im trying to unpack this .pak file, i can't apparently, can anybody help me?

https://drive.google.com/file/d/1eeuMq2 ... sp=sharing

(is a oculus Quest exclusive game, i want to modify it to kill the Level boundaries, that force you to go back into the pause menu) Called Time Stall VR, DM me on discord xAstroBoy#1337 if yall need the APK or the obb file.

[spiritovod]

@xAstroBoy: I've updated 4.25 script, which is available via my signature, it now supports the game properly, but you'll need to have "Time Stall" in the path to game package for the workaround to work. You can also find required for some assets key in separate topic in my signature.

@winkiller221's issue was already solved before in latest 4.25 script: viewtopic.php?f=9&t=1005&start=1980#p68373

Got a error when unpacking, my HDD is not full, there must be something wrong with the script or unpacker.

[spiritovod]

@xAstroBoy: I don't know how you've managed to get this error, since updated script works fine with the provided package and it's fully extractable (logs). As for other questions, they're out of the topic scope, since it's for general questions about UE4 packages and not about particular assets - so it's better to look for answers at some modding communities and check tools, mentioned in this post.

[ikyAhmad]

@ikyAhmad: Those things can be modified in memory at runtime, so it has nothing to do with this topic or quickbms.

do you know where is the Thread that talks about that??

[spiritovod]

@ikyAhmad: Certainly not on zenhax forums.
