Hello, i have changed a interior of one old(Trainz 12 or 2009) loco to a new one of a Trainz 2019 loco but only the controls and the screens are visible, the role cabin structure are invisible, and the number of amps, psi etc are not changin in the screens, maybe it's because is "payware" content(the content come with the game so i dont understant why this is considered payware)?? The cabine are of CSX C40-8W yn3 (ex-CR) by norfolksouthern37, and i cant see how it is configured because i cant edit or see "payware" content in this trainz, someone know how the inteior and cabin shell is configured in config.txt file and can helpe me?
