I have provided two versions of the editor:


It does have a desktop app which can help locating and opening saves.

Download here: https://github.com/iebb/F1MSaveApp/releases/

(The easiest way. It can directly manipulate the savefile)
(under "Logo Editor" section of "Custom Team" tab)




(You can edit without the savefiles. Export your creation and you can import it into Savefile Browser)

We can use Forza Painter to convert any image into ellipses, thus making it possible to use in F1M 24.

Steps:

1. prepare your image in png or jpg format. 256x256 resolution should be pretty enough but anything works.
   
2. get forza painter from https://github.com/forza-painter/forza-painter (download zip)[github.com].
   
3. drag the image onto forza-painter.
   
   
4. choose a profile based on tradeoff between quality and time required. the preset c or d should be fine
   
   
5. confirm
   
   
6. there will be a new folder named [filename], and it contains some json files -
   [filename].[N].json means it has N shapes. the more shape the better quality is, but there's a risk of crashing the editor if it's too high (should be safe under 1500)
   
   
7. open it with notepad or any other text editor. copy everything
   
8. paste the contents into "IMPORT FP"
   
   
9. profit (remember to click the save button!)
   

On July 27, I have implemented a web-based geometrizer which could replace the Forza Painter software.

Just use the "Import Image" button, and choose your configuration between quality and performance - you are one click away from getting your image imported.

If you are using the web version of Savefile Browser:

• locate your savefile from %LOCALAPPDATA%\F1Manager24\Saved\SaveGames
  
• if you are not sure which to replace, use autosave.sav. you can make backup first
  
• drag it onto Savefile Browser, switch to "Custom Team > Logo Editor" tab
  
• make changes
  
• click save inside the editor
  
• click export savefile, and manually replace the savefile with downloaded one.

If you are using the desktop app:

• selecting your savefile from the left sidebar
  
• switch to "Custom Team > Logo Editor" tab
