Hello, how I can make custom grids for modded cars such as the Ferrari/Aston/Ford which don't have XML?
I looked into this for you. I think that modded cars such as IndyCar mod should come with a file like UserData/CustomAIDrivers/Carname.xml
If you want to create your own or edit the drivers in the given xml file you can do the following,
On the welcome screen, you should choose the option called Existing Modded Grid (Or if you disabled the welcome screen it will be available in the menu at File > Import Modded.
You want to choose that file that comes in the mod package and it will open it for you. You will be able to edit it and change any values you want.
If you want to Create a fresh grid with that class you shoul dbe aware that this utility also imports the vehicle class for a modded livery if that option is chosen. You can see that class's details in Library > Vehicle Classes > Edit.
You can change it's name but I suggest not changing anything else like xml name or Livery Names unless you know what you're doing and are assembling a class from multiple mods.
If you want to use this class for a new Grid you can now do so. By either selecting File > New > Empty Grid > Generate. and then after creating and selecting your first driver you can check the Choose Livery option. It will pop up a window asking you to choose a class. Simply choose the new class you created (It should be at the very bottom)
You can also use this class in File > New > From Table Generator or File > New Grid Generator (But you can't use NAMeS on this grid as NAMeS doesn't have modded cars (NAMeS+ does. I think)
NOTE: This class will be available until you close your utility. You can now import grids using this class as Regular Import grid rather than modded. If you close the program you will have to reimport this file as a modded grid.
If you want to persist this Vehicle class the only thing you need to do is press the Library > Vehicle Classes > Export and then Library > Vehicle Classes > Import and choose your new file. It will now always load that file instead of the default one.
(Note to self: make this process more streamlined in the future)
I hope that answers your question, I will be happy to answer any of your other questions if you have any.
