OK, so, you want your own badge? Well... As long as you have your 3ds max, AND your badge is round, you can make your own pretty easily.
Needed:
3ds max 2013 with the export plugin
image editor capable of opening .dds files (gimp can do it with a plugin)
1. Download the attachment, unpack it anywhere.
2. Edit the provided .dds file, so that it's your badge. Save the file under a
unique name,
in the folder you have the 3d file in.3. Open the .max file, and go to the material editor.
4. in material editor, go to the box I marked goldish in the image above, and change the bitmap source so your new badge image file is loaded in instead.
5. export the badge and its uv mesh to .kjc and put it in game as usual.
6. copy the texture file to /assets/meshes/carparts/sharedtextures.
7. copy the parts.lua file from Alfadave badge folder to your own badge's folder.
8. enjoy your personal badge.
The 3d file can also serve as a template badge 3d file, so you can see how large a badge should be, how is should be positioned, how the uv mesh should look like, so you have the material, etc.
