I've seen a number of people trying similar things to this, but none with exactly the same questions. I, at one point, exploited a glitch to edit the MAS files of (postipate's wonderful 1975 mod) and do custom skins, performance, drivers etc. i've recently reinstalled the game and want do do something similar, but a more legit and method that actually works and i can remember. What i want to do: - Create and edit car skins, driver helmets, driver suits, driver + team information - be able to add and remove drivers (e.g run a "season", then remove drivers from the field, remove default drivers of the mod etc) - be able to edit car performance (e.g power multiplier) What i don't want to do: - Use the virtual ride method: last time i found this would glitch about. Not sure how it is now though, and will use it if necessary. TLDR: I want to edit the default drivers/cars of a mod if possible. also, not sure if this should be general discussions or modding since i've seen similar threads here before.
