Post by ZENHAXnumba1 »

the game is named Creative Destruction by Netease(also neoxengine)
some npk(script.npk) can be decompressed but it is encrypted
is this possibly new compression method from neox engine?

i tried using . 's script & no luck
also tried to scan it using offzip, but it always i always get result of 0%

file sample(res.npk, which may coint ui,txt,etc)

Everything works perfectly.
I have no idea what script you are using :)
Please remember to use EVER the latest version of quickbms and script, you will save both mine and your time :D

And no, you can't use offzip in this case because files are compressed with lz4.

I guess that 0000018a.dat doesn't come from the res.npk you uploaded, right?

You are right about the encryption, indeed at the end of the file there is a base64 string, maybe a signature or something else.
Can't help with stuff which is not part of the original format or custom encryptions used in specific games.

its from script.npk(same game) , and yeah it has custom encryptions like the other npk with low file sizes
tho i succeeded the recompilation of npk, script works 1000% 8-) (meshes are easy to rip in this game :V)
