The files are a single mas file, this system does not work any more. Extract the files and place them in the skin folder for that car and they should work OK. A lot of people are making this mistake with the new painting system. Hope this is of help.
I have just tested your update and the AI cars show all white but they are OK in the show room. I unpacked the mas file and copied the files into the folder for the car and the AI cars work perfectly. Leave the mas file in the folder as well. As I said in my previous post the single mas file does not work with the new paint system. Hope this is of assistance to you.
The only thing I can think of is that the mas file works OK on your computer because it was created on that computer and when it's transferred to another computer the mas file does not get read correctly which then causes the problem of the white AI cars. I have downloaded other peoples skins which have had the single mas file and not one of them has worked correctly but when extracted work perfectly. This is the only thing I think of which could be causing the problem. I suggest you upload extracted versions of your skins so they work for everybody.
The mas file created when you click on reload isn't actually required. It can be deleted, provided rf2 is closed and then restarted. If you download my Chris Hoy Oreca skin you'll see there is no mas file in the folder and that skin works perfectly. The skin name points to dds file and not a mas file in the rcd file. It was only a thought about going from one computer to another was causing the problem.
I don´t know how.
