I’ve just made invisbile the body so that you can see what is the problem: the car has a Mechanic Fuel Injection system with performance intake, which suddenly disappears once you come to design / fixtures or any photoscene.
I’ve also tried other bodies, put other engines with EFI, turbos or carburetors but the problem remains the same: parts of the engine is not visible, for example here intercooler and exhaust are missing…
Is there someone who had this trouble and knows mayble how to solve it?
