Thanks to you for your help @jorge.j.caballero, I didn't see my synthax error (bodyconfig2 is better lol), I'll fix that very quickly I just finished testing

For the fuel tanks yes it is the same principle since CMS2015, the tanks will remain like that until I can devote myself to a possible 3D design of mods (working 3D models to be able to integrate the tanks and make other ideas on other models ahah).

Great config mod! You need to rename the config file as "config3" as the bodyconfig file has that number. The fuel tanks issue is due to the game engine not rendering "internal parts" that are not suppossed to be seen during the track events. It does the same for suspensions.
