In-Game Preview Pictures

How do I make my own preview pictures for mods (for the selector menus)? I tried adding one for the Cadillac by matching the resolution and "default" file name of the mods with working pictures and re-zipping, but it didn't work and actually broke the mod until I restored it.

 

You have to make a png with Config name. If one of the Configs is named Cadillac it should be cadiliac_yekl.png
But info.json has to be saved to
Info_cadiliac_yekl.png
And pc file Cadillac_yekl.pc

Can't help with default pic tho

 

You'll find out pretty easily by taking a look at the game files.
For the default pic you choose the name "default.png", for the others you take the filename of the .json and use it as image filename.

 

Thanks for the help!
