The semi-complete guide to replacing assets.
 
 

◄—INFO—►

Hey hey! This guide is being worked on when I have time.
 
Currently the Models are an enigma that won’t load into the game sadly.
 
Ask in the comments if you need help with anything, or have figured out something xoxo.
 
 
Thanks to May – [steamcommunity.com]  once again,
 
if they didn’t direct me to start looking for a sound mod solution,
 
I would’ve never found a Texture/Mesh solution.
 

 
This will let you do stupid things like
 
Replacing guns with screwdrivers
 
 
And the texture of anything with
 
literally anything.
 
 

 
 
Important Note:
 
Your mods WILL break when the game is updated,
 
and will need to be remade.
 
HOWEVER, your save files shouldn’t be affected no matter what you do.
 
This only changes the assets of the game, and doesn’t touch the code at all.
 
 

Regarding usage of models outside the game

 
For those intrested; Yes, you can use models from Project Nexus for other things,
 
as long as you give credit to the Dev team, along with a link to the game’s steam page.
 
 

 
 
 

Setup for Textures/Models

The tools you will need are

 
[Unity Asset Bundle Extractor] – [github.com]” rel=”nofollow noopener”>[Unity Asset Bundle Extractor] – [github.com] 
 
To extract, and replace assets. [MANDATORY]
 
[Asset Studio] – [github.com]” rel=”nofollow noopener”>[Asset Studio] – [github.com] 
 
To view models, textures, and export into .OBJ format. [Optional, but helps a ton.]
 
 
STEP 1.
 
Create two new folders anywhere on your computer,
 
one for unmodified files, and a second for modified files.
 
 

 
 
STEP 2.
 
Navigate to the Madness: Project Nexus folder
 
 

C:\Program Files (x86)\Steam\steamapps\common\Madness Project Nexus 2\Madness Project Nexus_Data

 
Step 3.
 
Open AssetStudioGUI.exe
 
 

 
 
Step 4.
 
Open the Madness: Project Nexus folder inside Asset Studio
 
 

 
 

 
 
 

<File Names>

I’ve made a seperate guide which lists the most common files you may want to edit.
 
https://steamcommunity.com/sharedfiles/filedetails/?id=2718634676 – [steamcommunity.com] 
 
 
 

<—Textures—>

Step 1. Find your texture, and extract it into “modified” folder. (Make sure it is a Texture2D)
 
 

 
 

 
 
Step 2.
 
Open the original file, this is necessary for importing stage.
 
 

 
 

 
]
 
Make note of what this file is.
 
 
Step 3.Open and modify your texture, then save it.
 
 

 
 

Continue to “Importing” section

 
 
 

Importing Texture

Step 1.
 
Open Asset Bundle Extractor. (From now on referred to as UABE.)
 
 

 
 
Step 2.
 
Make a BACKUP of the Original asset, and place it in your “Vanilla” folder.
 
(That’s the one I told you to make note of.)
 
 

 
 
Step 3.
 
Open the BACKUP file.
 
 

 
 
Step 4.
 
Find the Texture you changed, then click on “Plugins“, and under plugins on “Edit“.
 
 

 
 

 
 
Step 5.
 
Click on “Load” next to Texture option. Don’t touch anything else.
 
 

 
 
Then find your modified texture, and open it.
 
 

 
 
Then confirm the editing.
 
 

 
 

Continue to Applying ingame.

 
 
 

Applying Ingame

Step 1.
 
Save the modified file into your modded folder.
 
 

 
 

 
 
Step 2.
 
Replace the sharedassets file in the game directory.
 
 

 
 

You’re done!

 

 
 

 
 
 

◄—⚠️ MODELS | DISCLAIMER ⚠️—►

Currently, this section isn’t finished.
 
 
For now,
 
You can only replace models from the game with the models from the game.
 
 

---

 
I’ve been trying to crack this for the past few months,
 
but haven’t been able to succesfully import a model into the game properly.
 
 
So far I’ve collected that:
 
Unity 2019.2.6 is the version the game runs on
 
Blender 2.79 is the version Krinkels uses.
 
UABE is able to import the model, but it doesn’t show up correctly.
 
 
If anyone wants to take a shot at it, please do.
 
If you manage to figure it out please contact me.
 
 
 

<—Models—>

Step 1. Find your model, and open the Original file.
 
 

 
 

 
Make note of what this file is.
 
 
Step 2.
 
Now launch UABE and open the file in which your model was located.
 
Then search for your model.
 
 

 
 

 
( press F3 until you reach the “Mesh” section. )
 
 
Step 3.
 
Once you find the MESH of your model, click on “Export Dump“.
 
Let the program save the file somewhere on your PC.
 
 

 
 

Continue to “Unity and Converting” section

 
 
 

Unity and Converting [PLACEHOLDER]

IGNORE THIS WHOLE CHUNK.
 
 
 
ITS UNFINISHED AND WILL NOT WORK

 
CONSIDER A PLACEHOLDER
 
If you want to import Custom Models you will need unity version 2019.2.6
 
I cannot stress this enough.
 
If you use a different version UABE will not be able to open your file,
 
so don’t go asking in the comments like a bozo and just read alright?
 
 
After modifying your model/replacing it with another, export it as a .OBJ type file.
 
 

 
 

 
 
This is where things get complicated.
 
First, you will want to install version 2019.2.6 of unity.
 
 

 
 
Then create a new 3D project, and drag your .OBJ model into Unity.
 
 

 
 

 
 

 
 
Make absolutely sure the model shows up under the scene hiearchy
 

 
Save the project, and Build it with the Windows/Linux/Mac standalone setting.
 

 
 

 
 

 
 
 

Replacing models in the game

1. Find the model you wish to replace.
 
In this case I will use the Throwing Daggers.
 
And click on Import Dump
 
 

 
 
2. Select the model we exported earlier.
 
In this case it is the baseball bat model.
 
And open it.
 
 

 
 
You can see that the file has been succesfully replaced by the little star next to it’s name
 
(marked in green in this image)
 
 

 
 
3. Now just save the file outside of your main Project Nexus folder.
 
Make sure you DO NOT rename the file.
 
 

 
 
4. Now finally, take your new .assets file, and drag it directly into your M:PN directory.
 
Replace the files when asked, and you’re done!
 
 

 
 

 
 

Good job!

 
 

 
 
 

◄—Setup for Sounds—►

DISCLAIMER
 
Sound editing is very buggy, and may break your sounds.
 
If this happens, delete the StreamingAssets in your game’s folder.
 
And make steam check integrity of game files.
 
 
You will need FMOD Bank Tools – [dropbox.com] 
 
We will be needing it to compile and decompile the .Bank files.
 
And a sound editing program of your choice with .WAV support.
 
I’ll be using AudaCity – [audacityteam.org] .
 
 
 

Sound Extracting

Launch FMOD, then select “Bank Source Folder” and set it to
 
 

C:\Program Files (x86)\Steam\steamapps\common\Madness Project Nexus 2\Madness Project Nexus_Data\StreamingAssets

 
 

 
 

Now wait.

 
This will take a while (more than 30 minutes),
 
because the game has many high quality sounds, and many variations.
 
Once the progress bar is done, open your folder, now filled with “ProjectNexus2Audio“.
 
 

 
 

 
 

 
 
I recommend you make a backup of the extracted files.
 
To avoid having to re-extract everything.
 
 

Once it is done, continue to the next section.

 
 
 

Sound Editing

Step 1.
 
Open your “ProjectNexus2Audio” folder, which will now have appeared in your empty folder.
 
And pick the sounds you will be editing or replacing.
 
 

 
 
I will be changing the N911 firing sounds.
 
 
Step 2.
 
Open AudaCity, or a sound editing program of your choice.
 
(With .WAV filetype Support.)
 
And load the sounds you will be editing.
 
 
Step 3.
 
Replace the sound inside AudaCity, or your preferred program.
 
Then Export it as a .WAV
 
 

 
 
Make sure not to accidentally rename your files!
 
 
 

Sound Importing

Step 1.
 
Return back to FMOD Bank Tools.
 
And make sure WAV DESTINATION FOLDER is still the same.
 
But change where BANK SOUCE FOLDER goes, to make sure you don’t overwrite the wrong files.
 
 

 
 
Step 2.
 
Click on “Rebuild“, and wait for the program to repackage all the files.
 
 

 
 
You can keep a track of the progress by looking at the CMD output.
 
 

 
 
There are 3219 files in total.
 
 
This will take a while.
 
 
If your CMD gets stuck, and doesn’t show any text,
 
close the program, and redo the previous steps from this section.
 
Don’t worry, the things that were already finished will stay finished.
 
 
Notes:
 
Make sure to NEVER replace “ProjectNexus2Audio.strings.bank”
