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.

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"

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!
- Go back into the root of folder "Import in game". 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.
thankyou.. waiting for 3d model photoshop :)
 
Hey guys!
I come from F1 modding and want to start on MotoGP too. Do you know if modding disables steam achievements? For example, in F1 helmet modding does not interfere with online play and achievements afai. So what about helmets and bikes modified here?
Cheers

No it doesn’t disable them and you can do whatever you want with mods enabled, even play online

I’m not 100% sure but I’d say it’s because your project path is so long (that’s the only reason I’ve ever had a failed cook)
 
Hi,
Stupid question but I wanted to know if it was possible to do the same thing or something similar with the 3d models of MotoGP, it would be much easier to edit textures

Ok never mind, it fix. Turns out the problem is when i drag the file it fail to cook,
but when i import manually it worked, which is kinda weird. Btw thanks for helping
