WY uses Oodle's Leviathan compression, which is not supported by these tools.

Also it's not worth it to recompress those files. It will take 4-5 hours on 4-threads CPU and you will save only 3.5 GB.

Kraken and Leviathan got a serious performance hit while switching from 2.5 to 2.6/2.7.

Example chunk compression time for leviathan level 5:
2.5.2 - 11 sec
2.6.0/2.6.2/2.6.3 - 3 min 20 sec

So it became 18 times slower, with a final size of data a little bit smaller. In some cases it's close to lolz.

then add more threads
also good to know there is something that uses leviathan, should be easy to add

Well, saving of 3.5 GB and installation of 4 hours on 4-threads PC is not something I can tolerate, and I'm very patient in terms of installation

As for leviathan here, devs did an update, so the unpacked size is nowhere in the chunks and leviathan doesn't return error code on a wrong size, so you can guess what can happen

If you still want the sample, ping me you-know-where

Hi Razor
do you have any plan to add leviathan and hydra?

As always, most of game files are encrypted.

Yes, but the decrypted file also don't decompress. It is possible the keys do not fit

[FitGirl]

Of course they don't fit. New game = new key.

WWE 2k20 uses oodle but the scanner doesn't find any oodle streams ?

any one tested it ?

[ZAZA4EVER]

I tested it with multi oodle versions ... I think game has encrypted files ... Need password

Huh? Why do you try to use Leviathan over ENCRYPTED data, already compressed with Oodle Hydra?
