I see. It's caused by the decryptor which didn't update the entries when they're unencrypted. Redownloading the decryptor should work.
Thanks so much mate, that got it working perfectly. Really impressed by the unreleased characters in this game lol.

Hi,

This tool is awesome. However I ran into an issue, when tried to unpack
Creative Destruction npk.
It doesn't matter which bms script I tried, none of them worked.
Aluigi's nxpk script is working, but gave me 18k nameless file, and it is really hard to get what i need.
Ccould you please take a look?

Thank you!

Coz the data is encrypted.
Here's aluigi's srcipt with extra code for extension filtering. Should handle all cases other than Cyber Hunter.

Is there a way to solve the naming problem in Netease games? Often no corresponding map can be found.

Use the script posted above for any games other than Cyber Hunter, MARVEL Super War and Onmyoji Arena. If they output without proper names, then they don't have any.

Thank you so much for the tool, can you somehow convert those animations to make them able to use in fbx?

Hello Bigchillghost, thank you for allthe awesome tools you made, I tried to extract models from Marvel Super War of today update, but I have the following error when using tool on a high model npk file:
I used NetEase NPK (EXPK) Archive Decryptor, then quickBMS on the decrypted npk with npkUnpackerExtFilter:
Image

Did I do something wrong or npk are now different ?

Samples as of Sea release :
High models :

Low models :

Have a nice Christmas and New Year btw everyone :)

According to the error message you were using the correct script so you did everything correct. :D

High models :
Did these files come from the obb package or you downloaded them in game? According to the info table in these files they seem to be using another compression algorithm. I'll test it later.

Low models :
For this npk file it's a field in the header that makes it bypass the decryption on the data. Just change the byte at offset 8 as below:

That should do the trick for now.

EDIT with updated hero low.npk : Very sorry, I've just noticed that I have several obb file in Marvel Super War and I think I uploaded an hero low/npk from a previous update(the high asset I uploaded are for sure from latest update) I opened this time the latest obb I have with the following 08 value :03 this time :
https://www.mediafire.com/file/ksxhok7j ... ad.7z/file

Thank you Bigchillghost!, the byte 08 trick worked perfectly for the hero.npk (after decryption and using same bms script) for low model :)

The High model npk comes from downloaded asset via the game, they have an option to download high quality asset that gives 3 new file for higher hero, scene and sounds file.

That explains everything. They changed the encryption key, though it's still using zlib compression. Guess this method is blocked for now untill the new key is found. :oops:

Well the compression is one of the oodle algorithms actually. And the first 255 bytes of the key are:

Oops... Seems that I zipped the file when it's been opened by an hex editor.
