The Pre Alpha was leaked today so I was curious if we could possibly extract anything from it, models, textures, etc.

Samples: http://www.mediafire.com/download/ec1rn ... amples.rar

Thanks in advance!

I think that the filenames are obfuscated, but for the rest this script should do the job:

Thanks!

OP didn't include the str file with the filenames, here it is


screenshot of all the files in that directory


If you need more samples i'll zip up that whole folder.

Thank you!
49066 files found in 29 mins 55 secs from fsys files



edit
hmm file sizes aren't adding up
fsys.pak.00-05 are 5.75 GB and the total size of extracted files is 553 MB..

fsys.pak contains references for 36778 files.
There are no other information in it.

strange, i used a batch file to collect all extracted file names and it confirmed 49066 files with no duplicates.

last thing recorded in the QuickBMS cmd window


i'll extract again to double check nothing went wrong but everything seems right or else those extra 12288 files wouldn't exist.

Maybe it's my setup but I'm getting nothing but an error when I try to use the script with QuickBMS on the .pak files.

There was duplicates when i went to extract for the textures,rax and others but not sure if it's really the same file or a new one with the same name.

no duplicates for me, i didn't get any prompts to overwrite anything either.

@ggctuk
You got to have all of these in the same folder
fsys.pak
fsys.pak.00
fsys.pak.01
fsys.pak.02
fsys.pak.03
fsys.pak.04
fsys.pak.05
fsys.pak.str

Hmm. This is what I get:

looks like you need to update your version of quickbms

I see. It's running now. Wow, there's a lot of stuff in there. Here's hoping we can convert it all into something useable.

Not really the script isn't doing something right cause everything is 16kb or lower.

It also seems like there's less files coming out than there should be.

I can only speak about the 2mb sample that was provided and everything there is perfect and matches the results of offzip with 914 files extracted.

It will be best someone to send to aluigi the full files so he can make more tests on them,if he want to download 5 Gb files however...

I have made a simple test here for calculating the total size of the archived compressed data and the decompressed ones, this is the result:

Code:

PAK: 0   ZSIZE: 0x3e9389fa   SIZE: 0x62c10973
PAK: 1   ZSIZE: 0x3f9cffdb   SIZE: 0x4b0fb334
PAK: 2   ZSIZE: 0x3f9246f7   SIZE: 0x778c1686
PAK: 3   ZSIZE: 0x3f2c2e65   SIZE: 0x92c45fe8
PAK: 4   ZSIZE: 0x3f32fe5c   SIZE: 0x90eece20
PAK: 5   ZSIZE: 0x308cd948   SIZE: 0x72360ed0
TOTAL 0x000000016caed6d5 0x00000002bb461005

It means that at the end of the extraction you should have 11 gigabytes of files (49066 files) in the output folder.
In fact it's not possible to spend half-hour for extracting 500mb and you are getting no errors from quickbms.

(49066 is the correct number of files, my previous number was a mistake)

553mb of files in half hour of extraction with no errors may sound impossible but its exactly what is happening.
I tried 2 extractions with 2 different versions of quickbms, same outcome.
i think files are getting trimmed down to 16kb or else this game must have a lot of low poly models.

anyway I got this from assets\bf\ob_xb_v184\capital_ships\cis_cruiser_exterior_30_scaled_lod\novodex.rax with hex2obj

no idea where the UVs are but i suspect they might be in ob.rax

This happens with the audio files too. It only gets one second out of the .wav files even though the headers for these files indicate that there should be more (IE a minute's worth of audio for cutscenes).

aluigi, posted Fri Jan 22, 2016 7:51 pm (10948)

Ok so it means that the files are stored in chunks.
All the files in the first 2mb were under 16kb, that explains why they were not visible.
I will make some tests and will keep you update.

Script 0.2

Please note that few chunks have a size bigger than 0x4000 which means that they may use a different algorithm or something else.
For this reason (because I don't have the whole archives), I have opted for comtype zlib_noerror so you will get no errors.
Anyway let me know what is the results because I can't test it at 100%.

It's just one of those chunks with 0x7fe8 and I think to have understood the trick without downloading the archives.
Hold on...
