DisUnity - An extractor for Unity games

[barracuda]

Hi barracuda,

First up, let me thank you for creating DisUnity. I am a soundtrack junkie so now I can finally get my mitts on the music from the games I play.

I'm having some trouble with .resS files. When I try to extract a sharedassets#.assets file with a corresponding resS file, I get "Audio clip {0} uses an external .resS file that doesn't exist!" for each file. Does DisUnity only find the .resS files for resources.assets?
All .assets and .resS files are in the same directory, by the way.

DisUnity should automatically locate and load the corresponding .resS files for every asset file. If you have a pair of files that doesn't seem to work, you may have to send them to me for investigation.

And I also just noticed that the log message is broken, the placeholder {0} should actually contain the audio clip name. Shall be fixed.

Edit: It turns out that the whole .resS loading system is currently broken in 0.3.0. It will be fixed in 0.3.1.

hi~~barracuda

i use DisUnity0.31 extract Pineview Drive game, sharedassets2.assets，
not work,get some error。

[merlinsvk]

Probably the same error as I get. I have only 2GB of RAM and this error occurs only with files ~500MB big (or bigger).

Code: Select all

I want to get the compiled scripts.
The game I'm looking at uses monoscript so a dll is generated.

How can I extract the DLL?

EDIT: got it, I used bundle-extract

[Catonx18]

can it unpack anim files and 3d models yet?

Hi! Thx for useful tool.

Sometimes extractor crhases while working Texture2D data with command 'extract',

but all ok with command 'extract-raw'

[Slandey]

can it unpack anim files and 3d models yet?

Anims: NO
3D Models: YES

[Catonx18]

But it won't extract models into .obj format it just has an error.
please help!

[Teddy84]

Thanks a lot for your tool.
However, I get an error as soon as disunity reach a 3D Model to extract...

game was made using unity 5. i also tried disunity 0.5.0 but same here. anyone help

[DrMcCoy]

So i have disunity 0.3.4 [...] game was made using unity 5. i also tried disunity 0.5.0 but same here. anyone help

0.3 works best with Unity 3.x and has most of the original extraction features.

=> DisUnity 0.3.4 can't extract Unity 5 (nor 4, for that matter) data files.

0.5 is a code rewrite to properly support all Unity games from 2 to 5 that also comes with unit tests. Right now, it only supports raw file reading and writing without any object deserialization, therefore it also can't extract any asset data directly.

=> DisUnity 0.5.0 isn't ready yet either.

TL;DR: You can't extract Unity 5 data files with DisUnity.

Thanks, your program is amazing, it already helped me once)

Hi barracuda,

First, I'd like to thank you for creating this tool in the first place: the only other tool I've been able to find along these lines is the DevXDevelopment application - which I can only run as a trial version, since I don't have the 258 dollars to spare to upgrade it to the full, object-extracting package.

The file I'm interested in extracting is a demo for the 2010 Gorillaz "Escape To Plastic Beach" game: the motivation being to obtain the materials and objects necessary to render the "Plastic Beach" island in Unity. According to the DevX trial, the .unity3d file in question contains these as several .obj and .mat files. According to UniPlayer.exe, the demo runs on Unity 2.x, due to the game being released over 7 years ago.

Having run DisUnity ver. 0.3.4 upon it with the command "disunity extract GorillazDemo.unity3d", it has successfully managed to retrieve the following kinds of files: .tga, .shader, and .dss: but every other file type, including .cs, .fbx and, crucially, the .mat and .obj files has not been brought through.

Attempting the "extract -f" command and parameter resulted in an "unknown option" error. I did successfully get the BINs of every file, but this did not lead anywhere due to a lack of BIN experience.

Is this problem due to the age of the game, or is there another workaround I can try?

Thanks for taking the time to read this.

[GianaSistersFan64]

Can anyone tell me how to use it step by step in more details? I tried to follow what's it says in this thread but i keep getting the same error message.

This is very outdated and it won't work with anything much newer of 2015 (if even that)
These are some alternatives, from the still-older to newest
