Maybe I can ask for your help. In the game (not devmod) I created a test car under "human driver" and it works fine, car and skin. Now I have followed the instructions by Mauro to bring it to devmod (maybe I will be able to create an f1 season) and I have created / copied the files including the missing dds etc Then I also created the .veh By starting the devmod, however, I have a problem: the car is all white; or better: driver and helmet and tires ok, but the whole "painted" part (ie the parts of the skin, but also the wheel rims) are completely white ... I discovered that the problem is due to "MaterialOverride =" xxxx.json "; if I put the file name of an already existing one (for example ligier 77), the car is ok, with the colors of the skin defined by me etc, but if I use my json (which if I understand it is created automatically when the car is created, right?) then I only have white for all car + rims Well, I have to say that rfactor2 is still new for me, I do not have the modding know-how, but when I found this great mod I decided to invest time in rfactor2; the “material override” topic is not clear to me at all ... I would like to know more about it but if my goal is to create one or more F1 season series (of 70's F1 cars) with this mod, should I care about that or just "make it simple" and use any of the other "Materialoverride" files already defined in the mod without any problem for my new cars ?
