How to make sure AI never changes color in AI Traffic?

Hello! ive bought beamng 2 days ago and im usin g the ai traffic to roleplay, but i have a Tesla Model 3 mod, sometimes, when i spawn the car, putting it in white, then activate traffic, the car drives, then when it respawns it gets to an unrealistic color (e.g : Yellow, Green, Purple) is there a way to fix this?

things ive tried :
-going to settings - gameplay - allow swapping with traffic and it didnt work



this is an example : yellow isnt a tesla color irl. maybe i should change the factory palette..

 

There is an info_[configurationname].json file for each configuration inside the mod zip/vehicles/[carname] directory, copy this to C:\Users\[username]\AppData\Local\BeamNG.drive\0.34\vehicles/[carname] (most likely you have to create a new directory) and open it, look for "config type" line and set it to "custom" and save.

 

is the main-materials.json the file i should take?

 

No, you take the configuration you want to change. If you are not sure about the names of the configuration, check the pictures of the same name. Or save a configuration, although this will not create an info-file. Or if you want to have every configuration have this behaviour, you can just copy all the info files and change all "config type" to "custom".
So each configuration consists of three files: picture (configurationname).jpg; specs (configurationname).pc and info-file: info_(configurationname).json . It´s this info-file you want to change.
