If you click the "`" button on your keyboard in beamng, it should open up a LUA Menu, then you can find why it's not working.
I've attached an example info.json for one of the cars from my config pack. You can open that and look at how it is laid out or you can look here: Code: { "Configuration":"Santa's Backup", "Transmission":"Manual", "Description":"Sometimes the old sled doesn't get the job done fast enough.", "Drivetrain":"RWD", "Value":25000, "Performance Class":"3", "default_color":"Pearl White", "Config Type":"Custom" } Each of those lines has a different use. Everything in Bold is what you can edit, everything else must stay the same. Here's a brief description of what each line means: Configuration - This line is where you put the name of your car Transmission - Manual, Automatic, Etc Description - Here is where you put the description of your car Drivetrain - AWD, 4WD, FWD, RWD Value - The Value of the car Performance Class - The "class" of performance that the car is in - the higher the number, the more performance the car is capable of default_color - The default color of the car, you have to make sure that you're using the actual color name from the vehicle's paint menu Config Type - Factory or Custom
Does anything appear in the console? (Default key is "~") - take a screenshot of it and hopefully the error will present itself.
Look, at line 39 of your info.json.... you have an opening bracket like this one: [ but your must have a closing bracket like this: ]
