Hi. I am trying to extract a .PAK file from Monsters vs Aliens game, but every program that I use fails.

This is the file i'm trying to extract ( https://mega.nz/#!ImByVQCB!YWzNaza9ZJT4 ... 1sHYWUZ7Yk ), supposedly the Ginormica 3D model. I need it to use in a non-comercial fan-made game that some friends are creating, called Sizebox.

I was talking with Mygoshi of another related topic, like this and this another but it seems the case is different.

Can someone help me with unpacking these?
I thank very much for your help.

(Sorry my bad english)

I'm not sure it's a sort of archive, for sure not a simple format, so I leave some keywords taken from the file:
BuildMan - Wed Jan 28 16:31:25 2009
GS version 3.140.7
HighRez Windows WorldWide

When i try to open with some programs, i get this output:



i've seen in another program that the file is lzma86 type, but i'm not sure yet.

I've then renamed the file to BaseGinormica.lzma, and receive this output from Peazip:



And receive this text output when i test.

I have already tried to rename the file to the .lzma86 extension, but the error is the same.

here is a generic bms script attempt to extract all file in the pak

Code:

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

get FOLDER basename
findloc OFFSET binary "\x26\x00\x00\x00\x01\x00\x01\x00"
do
    goto OFFSET
    goto 0x30 0 seek_cur
    getdstring NAME 0x40
    goto 0x8 0 seek_cur   
    get SIZE long
    math SIZE - 4
    get SKIP long
    savepos OFFSET
    get CHECK long
    if CHECK == 0x20534444
        string EXT = dds
    elif CHECK == 0xAC44
        string EXT = aud //??
    elif CHECK == 0x4
        string EXT = mdl
    else
        string EXT = dat
    endif
    string NAME p "%s\%s.%s" FOLDER NAME EXT
    log NAME OFFSET SIZE
    findloc OFFSET binary "\x26\x00\x00\x00\x01\x00\x01\x00" 0 "" -1
while OFFSET != ""

i did my best to guess some extensions

for automatically decompressing lzma data without knowing the type of lzma and its decompressed size it's enough to use:
comtype lzma_dynamic
clog NAME OFFSET SIZE SIZE

I've sucessfully extracted all files, thank you guys. I've just to put the extension in some files, though i don't know what extension to put in anothers. I've identified 226 of 435 files until now.

Is there a way to list the original filenames with their extension in quickbms?

All files turned this way. I could only discover the extent of some. Take a look: https://mega.nz/#!Un5QCCLS!MPMyilHnequZ ... yXq-SX2-6k

the original filenames are stored in the pak but the extensions are not, you have to guess.
also when you extract the files with my scripts and you get a duplicate file prompt press "r" to
rename duplicates because there is some files with same name but different size.

edit
i combined the 2 scripts and added a check to guess extensions too.

Hello there.

I hope you're still interested in extracting the geometry and textures from the monsters vs aliens game despite it's been months since you've asked this question.

I found a tool that let's you extract the meshes and textures from almost any 3d game. It's called ninjaripper. You have to run it as administrator and start the game using ninjaripper in order to make it work. Simply load up the game so you see ginormica and then hit F10. Ninjaripper will then save every geometry along with their textures that you're seeing in the game including characters and map geometries inside the ninjaripper folder at "C:/Users//Documents"

Here is the link where you can download it:
https://gamebanana.com/tools/5638

I tested it on the monsters vs aliens game demo and was able to get the 3d models and textures from Ginormica, Missing Link, B.O.B, Insectorsaurus and the Alien Probe. I couldn't do the same on Dr. Cockroach because in the demo you can't play him. This may work if you have the full version of the game.

I've managed to import the 3d models of the characters into blender.

I hope that helps you. Best regards.

I tried to unpack .PAK files from the game, but i cant use any .mdl files in any 3D program. But .dds can be opened. How to fix this?
