this game will not get compressed alot i believe that you will save about 20% compression..

Based on what is this zlib? Just because somebody included xtool into compression method it does not means that xtool is infact used, nothing is expanded, it just gets skipped and it does nothing. You will get exactly the same "gain" if not using xtool:zlib at all, all gain (small) is from srep+lolz, xtool:zlib is just placebo.
This game uses xtool:kraken (pakchunk51-WindowsNoEditor.pak) but you have to decrypt it with xtool unreal plugin, use known key.

Maybe you can give the right library info for this game? because I don't know how to check it. Thank you

Use oo2core_9_win64.dll v2.9.5 or 2.9.9 with xtool:kraken and unreal plugin (search for key on known sites, I'm typing this from memory...) on
pakchunk51-WindowsNoEditor.pak
But other .ucas & .pak files are not encrypted and oodle compressed..unfortunately did not have time to test it more. But they are not xtool:zlib also, no gain over srep+lolz only method. Maybe there's something I'm missing...

[KaktoR]

You guys still deal with unreal engine slop?

It's always the same with UE:
Either zlib or oodle is used
crypted or not (use aes_finder on shipping exe to get the key if crypted)
If oodle is used, mostly library 2.9.5 or 2.9.10_lib2
Poor ratio especially if oodle is used (> 80%)

Danziel123 just doesn't learn. That's what.

XTool's GUI mode functions as a way to test library-based decompression, cut 500mb from the largest archive of a given title and then run that against your collection of libraries. For someone who has been on this forum since 2013 with almost 1200 posts, it's a bit worrying you seem to be unaware of these basic testing methods.

You don't need to cut anything from a file. There is a checkbox "Stop after # streams".
Just select folder which contains all oo2core v2.9.X libraries and let it run. Based on the results (processed streams and time) you know what library you have to use.
Mostly it's 2.9.5, sometimes 2.9.10 (lib2) and for the newer UE5 games in some cases 2.9.12 (last time I checked at least).

PS: In any case, never ever use library 2.9.6. This version has a memory bug you will notice.

If the file is encrypted I don't know how to check the library used. If it's not encrypted, I can check it myself. The file name used to cut a large file if I may know what is the file name?

For pak files you have to use ue4, not ue5.

Swiss File Knife (SFK), it's an exceptionally useful tool, as well as HDiffPatch, these two tools alone are very useful for more intermediate repacking processes, such as when specific data types need to be ripped to be processed separately from other data types, and then patched back in post-install.
