You did not include an m switch in your command?

Surely should be:

Also, what is the difference between "method (1 = games that use borderlands3, street figher v... format, 2 = games that use rune ii format)"

What is difference between Borderlands 3 and Rune 2?

I forgot to include it in the post above (I corrected it in the previous post).
But in the DiskSpan command it is inserted correctly.

I don't know, but it might be a different type of decoding, so you should use the correct -m# parameter.

No I didn't get it - read below:

No. Every minor version of UE engine have modification in pak files. This tool supports only two out of 20+

Might be Single file or Multi (PakChunk) file?

does anyone know where i can get the previous version of this as v7 doesnt work for me..
thanks

Can someone give me a sample along with a key of any unreal engine 4 game.

Thanks in advance.

Check Discord in a few hours please...

Fixed decryption bug

Notes

There was a decryption bug I didn't notice between R5-R6 which persisted in R7, sorry for inconvenience but I think it should work like R5 but with the features requested.
I noticed this bug after I remade a plugin version of this project for xtool but you can still use this.
Not forcing anyone to use the plugin, just stick with that you're used to but if you want to use the plugin version you can find it here.

Please use the new XTool with unreal.dll using -D3 instead because it has a slightly better ratio than UE4DT.

UE4DT slightly has some terrible results compared to new XTool by itself.

Hi Razor12911. I tested ue4dt R6 on the game SIFU. Works fine and allows a very good compression ratio after. The problem: on some configuration it gives error in installation, maybe it depends from the settings used, if you are using a large chunk size seems, maybe is that the problems, it corrupts some data and the installation gives error. I tested it on three pc with more than 1GB of chunk size and works fine in decompression but some of my downloaders are reporting error in installation. So I tried ue4dt R8 (settings ue4dt:c1024m:b256:m1) on SIFU and it must have some important bug, because it takes like forever to decrypt.. after 1h 30min it didn't finish. Tested "cls_ue4d" but the compression ratio is very bad after it. Also XTool(v0.3.9/unrealengine_R3/zlib/d1) is worst than ue4dt R6.

Provide sample and I'll take a look at the issue. If file is big, first 1GB should suffice.

yes on sifu it's not 100% full decrypted
(if i compare extracted files like .txt .json with uncrypted pak, there is some caractère missing/bad on some block, this during uncropress make crc issue)

I'm working on tony hawk 3+4 it's weird ue4dt not work

I'll upload a sample
