MGP21 MotoGP 21 Modding Tutorial

IMPORTANT: Following a recent umodel update, it is now possible to export models from the game.

This thread will teach you the very basics of modding the MotoGP games, I am going to try and explain more things this year but to start with we'll just stick to the basics.

Requirements:
1) Download these tools: https://www.racedepartment.com/downloads/motogp-21-modding-tools.42020/
2) You need Umodel (a.ka UE Viewer): https://www.gildor.org/en/projects/umodel
3) You need Unreal Engine Editor 4.25:
https://www.epicgames.com/unrealtournament/download
4) Also make sure you have Python 2.7 installed:
https://www.python.org/download/releases/2.7/

Text tutorial:
First of all we'll start with a bike skin as it's the main thing people want to edit and it's super easy, but once you understand the process you can try with something else.

Section 1: Export
-Launch Umodel
- Copy the path to MotoGP 21 into the text box (Normally it is: C:\Program Files (x86)\Steam\steamapps\common\MotoGP™21 or wherever you have installed it).
- Don't try to navigate to it as you'll have issues, just copy the path directly into the text box.
- Select "Override Game Detection"
- Select "Unreal Engine 4" And "Unreal Engine 4.25 Plus"

Then hit OK.
- You'll now have a window with all the directories of the game. Navigate to: motogp21\Content\assets\graphics\vehicles\bikes\cat001\chassis\chassis101'

If you're unsure of the ID of the bike you want to edit click on textures and then on "livery001.uasset".
This will load the first texture of the bike so you can see if this is the bike you want to edit.

It will display something like this:

If you want to return to the previous screen press "O" and it will exit the preview.

- Once you have found the texure you want to edit click on "Tools->Export current object" and Umodel will export the texture currently being viewed.
-Umodel will automatically create a folder called "UmodelExport" located where Umodel.exe is.
You can now find the texture (.tga format) and edit it!

Section 2: Import back in game
Part 1: Prepare your modded textures.
Basically we need to convert our modded .tga texture to .uasset.
- Launch Unreal Engine editor.
- Select Games.

- Select Blank Project.

- Select no starter content, choose a path to save the project to and then you can name it whatever you want. I'm going to call mine "Tutorial".
- Click on Create Project.

- Drag your modded texture here:

- Double Click the texture and change the Mip Gen setting to "NoMipmaps", this is so the texture doesn't appear blurry in game before loading fully.

- Click on File->Save all. This way you will not need to create a new project next time.
- Close texture window to return to the previous screen.
- Click on File->Cook content for windows. Wait till it finishes. You can close Unreal Engine now!
Part 2: Repack.
Go into "MotoGP 21 Modding Tools" folder from the rar. There you will see a folder called "motogp21". Inside it, you need to create the same Directory where you extracted the file from in Umodel:
"motogp21\Content\assets\graphics\vehicles\bikes\cat001\chassis\chassis101\textures"
Create the missing folders.
- Go to the location you saved the project to earlier (by default it will be "Documents\Unreal Projects\Name")
- Then from there go to "Saved\Cooked\WindowsNoEditor\Name\Content" here you will find the files Unreal Engine cooked for you. You should have 2 files. Copy BOTH of them into "motogp21\Content\assets\graphics\vehicles\bikes\cat001\chassis\chassis101\textures".
We're almost done!
- Now go back to the “MotoGP 21 Modding Tools” folder and double click repack command.bat
Once it's done (it's quick), you will have a file called "pakchunk0-WindowsNoEditor_X_P.pak". Replace the X with something else, like "pakchunk0-WindowsNoEditor_MyMod_P.pak"
Copy the pak file you created and paste into:
C:\Program Files (x86)\Steam\steamapps\common\MotoGP™21\motogp21\Content\Paks
or wherever you have installed the game. Make sure you copy it where all the other pak files are.
You're done! Check your mod in game.

can anyone help me to fix this? i was trying to remove some helmets brand like what I did in motogp 20 and ride 4, and also trying to change the logo in cusotmizable bike but the result became like this.
That’s caused by a missing/incorrect texture on the bike.

I’m not familiar with the previous mods you’re referring to, which files have you actually edited?

I made myself for ride 4 and motogp20 and it works but not in motogp21. I edited sponsorlivery12 and it's mask. for the helmets i edited helmet00 or 01 I forgot and it's mask.
 
IMPORTANT: Currently it isn't possible to open/export any of the models (except the Ducati) so please don't fill the thread with issues about that.

please tell me where i can find emojis?

Ah right, I assume you’ve messed up the sponsorlivery12 texture then, make sure you have definitely copied it from the cooked folder and not just the content folder of your project.
 
Yes, i know that, but wich values should i change. I modified the spanish treanslated value but nothing changed
I always modify both the source and the translation to be safe. But the reason nothing changes is that it’s only the first step in the process.

Once you’ve edited them you need to make an unreal project, go to the localization dashboard and rename the “game” namespace to “game_specific_names”

Then add all the cultures that milestone use (each folder that is present in the extracted game_specific_names folder is a different culture). This will generate a manifest and some archive files in the content folder of your project.

Next copy your modded manifest and archive files (the ones you’ve just edited) over the ones generated by your project.

Then go back to your project and click compile.

Once this has finished copy the localization folder from your project into the folder you’re packing and then your done, put it in game and it should work
