I’ve recently tried to paint the new McLaren Senna GTR and noticed I couldn’t paint most of the parts with carbon fiber, despite the Manufacturer Paint reaching those areas, which was kind of frustrating. So it came to me that beaing able to paint the whole car, or chosing to edit only a certain section (like those unpaintable carbon fiber parts) would be a great addition to the editor, which would also help with design masking. It doesn’t need to be limited to the unpaintable parts too, like choosing to paint only the car’s hood, or only the sides of the aero, just the windows, or being able to paint the car’s mirrors.
It could also solve some of the mapping issues in cars with multilayered parts, such as the Ford GT with the wheel arch and the middle of the car separated by an airflow gap, or any car with portruding parts that create a decal duplication, by separating the most outwards parts from the most inwards parts.
