VALORANT .pck

Post by eg0npro1 »

I have tried unpacking Valorants "Base_Audio-WindowsClient.pak", but after unpacking using quickbms and the "unreal_tournament_4_0.4.23.1a.bms" script im only getting .pck files from the .pak archive, is there any way to further unpack the .pck files?

This script for extracting the file from PCK:

And then this other script for extracting all the files from it:

I tried the scripts u sent earlier on before writing a post, after exporting from .bnk file using the armyoftwo script it looks like the .wav files are corrupted or something, when trying to open those with VLC it says "Unidentified codec: VLC could not identify the audio or video codec". I have attached an example .bnk and .wav files exported from it.

Some proof of concept in the attachment. Also, if you're spamming the same question in different topics, it would be nice if you could read replies for a change.

Could u show me the scripts you have used to make this work? There are multiple scripts for .pck unpacking and im not sure which one would work the best.

I don't think writing a separate topic for a separate game is "spamming the same question", because your "Look for Wwise-Unpacker or similar" reply isn't informative enough as there are different scripts for different games.

Long story short: if you see pck/bnk file in a UE4 game - it's a wwise audio container. Also, the mentioned tool is literally one-click solution to extract separate files in mp3/ogg from those containers (except system stuff like Bank_Char_Phoenix_SFX_Events in your case). "isn't informative"? Mmmkay.

@zh_user: According to screenshot, you're trying to unpack CEF (framework) file, which doesn't contain game files.

The .uasset comes out of the .pak file.

Previously .pck was coming out.

How can I solve it?
