Jurassic World Movie Maker app EFS1 files

[TheJJMan]

Hi there, new user. To put it simply I've been trying to extract the 3D models of this game:
https://apkpure.com/jurassic-world-movi ... viemaker-3
And after trying to use a QuickBMS script on it that I thought would work, it turns out the OBB file archives are actually "EFS1" files. The problem is though I have no idea how to make a script to unpack the game's contents and rip the models. The reason I want to extract them being it includes the 3D models and some animations used by ILM for the film itself.

If anyone here would be capable of making a BMS script capable of unpacking these OBB's that would hugely appreciated

The problem is that the index with all the information about the archived files is encrypted in some way.
Instead the files are normal and you can easily dump all the png images, wav audio files and others.
This is an old list of file rippers just in case viewtopic.php?f=17&t=712

I'm probably gonna sound stupid when I say this but do you mean the Jurassic World game file's in question are normal or they're encrypted?

Ok, in all the archives (of any game) you have two things:
- a table with information about the position, size, and usually name of each file inside the archive
- the data of the files in the archive

In this case the table located at the beginning of that EFS1 archive is encrypted.
While all the files have no encryption, that's why you can dump them.

Oh, right. So after using X-Ripper I've managed to export the textures and sounds (which is *SPAM* awesome so far), but after using that specific software there's no current option for meshes. Do any of those tools have an option to export (hopefully rigged) FBX/OBJ mesh files?

I guess it's better if you ask in the 3d section, maybe they have an idea on how to locate these files.

Oh alrighty, thanks for the help regardless though!
