@dixen

Thanks for the info. I tried ue4d but it crashed for me instantly. I will update the version to newest today.

hello! what am I missing for serious sam 2? i have seen other people get 2.2 GB, but my testing below shows a different size:
xtool+srep+lzma - 2.72 GB
also, a quick edit, i tried the same exact method listed on the index that was for serious sam 3 on here, but i get nowhere close to 3.3 GB, why?

I tested compressing the "Potentia-WindowsNoEditor.pak" file = 12.8 GB (13,779,750,608 bytes)

The configuration used with XTool was:

xtool_ue4:m1:k0xF31F7A2739450967A8143CD631C61433121A51FCFD20D362EF8884488BA3C263

[External compressor:xtool_ue4]
header    = 0
packcmd   = "PRE\XTool_2020\Win64\XTool.exe" precomp -mzlib+ue4{:option} -c32mb -t100p -d1 --dbase - - <stdin> <stdout>

I don't know why but the Arc.exe returns return a value less than the file size (4.683.535.036 bytes = Ratio 33.99%), but the destination file was 23.1 GB (24,890,734,065 bytes)
Could someone do the test combining with zlib (Xtool.exe -mzlib+ue4:..) to see if only this happens or is it a bug in XTool or ARc.exe?
See the images in the attachment to better understand.

Please make sure that you are using the correct parameters.
I ain't got that much experience, but recently played with the tools and the results were good. And try using Knight Compressor since it has built in options for parameters.

I just tested decrypt another ue4 plugin (No Razor12911) and xtool+preflate. No Compression with lolz

I am using Knight Compressor...I am using the highest parameters for xtool and lolz/srep and I still get that.

Make sure that the version of your game matches with the one in the INDEX.
Parameters doesn't need to be high all the time, makes decompression slower. They should be the same as the one mentioned in the INDEX.

Yakuza 6

srep+lolz on everything except *.usm and *.awb in which case use srep+lzma

Ripped vf5end.usm (credits video).

Final size: 28GB

You can use lolz on the audio/videos for size decrease but with this amount of data it will take hours for not much of a tradeoff.

SREP+LOLZ should've been used for .par files
