Customising Airport Ground Vehicles in X-Plane 12

X-Plane 12 has further expanded the possibilities for airport customisation, including the ability to customise airport ground vehicles starting from version 12.00. Ground vehicles in X-Plane are integral components of the APT.dat defined scenery. They are loaded early in the simulation, separately from the main DSF scenery data. This separation means that they cannot be replaced using the same methods as other library objects, such as the EXPORT override in library.txt.

This new feature empowers users to create and implement their own custom ground vehicles. These custom vehicles can be incorporated either locally within a specific custom scenery or as part of a broader library that can be deployed across multiple airports. It's important to note that custom vehicles need to be manually assigned to each parking location. There is no global replacement mechanism available for these specific assets. This manual placement ensures precise control over where and how your custom vehicles appear.

The Customisation Process: Step-by-Step

The process of creating and implementing your own custom ground vehicles involves several key steps:

1. Create Your 3D Model with Animations: The first step is to design your custom vehicle's 3D model. Crucially, this model needs to incorporate animations. The available datarefs for controlling these animations and sounds are located under the sim/graphics/animation/ground_traffic/ path. Referencing the X-Plane Dataref list is essential for understanding which datarefs control specific animations and sound events.
2. Create the FMOD Sound Bank: To bring your vehicle to life audibly, you'll need to create an FMOD sound bank. X-Plane utilises the FMOD sound engine for its audio. A template is provided within the “Using FMOD with X-Plane” documentation, which serves as a starting point. Within the SND file, you will define start and end conditions for your sounds, correlating them with the datarefs mentioned earlier. These datarefs can also be used as parameters within FMOD Studio to modulate sound events, adding dynamic audio characteristics. Ensure that your sound events are assigned to the Master Bank and correctly routed to the Exterior Processed > Environment bus. If you intend to apply signal processing, such as reverb or EQ, it's recommended to create a subgroup under the Environment bus rather than applying it directly to the Environment bus itself, as direct application can be overridden by the aircraft's bus processing.
3. Expose the Object via library.txt: For the World Editor (WED) to recognise and utilise your custom vehicle, it must be exposed within your scenery or library. This is achieved by adding an EXPORT directive to your library.txt file. For instance, an entry like EXPORT MY_LIBRARY/airport/vehicles/crew_car.obj custom_objects/crew_car.obj would make your custom crew car available.
4. Assign the Custom Vehicle in WED: Once your custom vehicle is properly exposed, you can integrate it into your airport scenery using WED. Within WED, navigate to the parking location for the type of service vehicle you wish to replace (e.g., fuel truck, catering truck). You will find a “Custom vehicle” field. In this field, you need to enter the virtual path to your custom vehicle from your library. Using the previous example, this would be MY_LIBRARY/airport/vehicles/crew_car.obj.

It's important to understand that while you can customise the visual appearance and sounds of your vehicles, the core behaviour is tied to the type of service vehicle you are replacing. The custom object will move at the same speeds and perform the same functions (crew car, GPU, fuel truck, etc.) as the default vehicle it replaces. The behaviour itself is not directly customisable through this method; rather, you are replacing the visual and auditory representation.

Example Resources

For those looking to get started, example vehicle models and FMOD Studio projects are available for download. These resources can provide a valuable starting point for creating your own unique airport ground vehicle assets, significantly easing the learning curve and allowing you to quickly implement your custom creations within X-Plane.
