1. detail_model

This defines the high-detail 3D model used in first-person and close-up views.
A correct model ensures accurate visuals and prevents clipping or floating parts.

⸻

2. model and lods

model is the main chassis model.
lods are lower-detail versions shown at a distance to improve performance.
Good LOD setup keeps FPS stable without affecting the player’s visual experience.

⸻

3. collision

This points to the collision model for the chassis.
It defines how the truck physically interacts with the world.
An inaccurate collision mesh will cause issues like invisible walls or unexpected bumps.

⸻

4. Shadow Parameters
• shadow_texture
• shadow_intensity
• extended_shadow_*

These control the style and quality of the truck’s shadow.
Correct shadow settings help the vehicle feel grounded and realistic.

⸻

5. ui_shadow

A simplified shadow model used in the truck browser and menus.
It improves the look of your truck in the UI and prevents awkward silhouettes.

⸻

6. tank_size

Defines the fuel tank capacity in liters.
Bigger tank → longer driving range, but also more weight when full.

⸻

7. adblue_tank_size

Defines the capacity of the AdBlue / DEF tank.
If this value is too low, the player will need to refill more often.

⸻

8. air_tank_pressure

Sets the default pressure of the air brake system.
Higher pressure allows more braking actions before the air compressor needs to refill.

⸻

9. nominal_voltage

Specifies the electrical system voltage, usually 24 volts.
This affects electrical behavior and battery logic in the truck.

⸻

10. residual_travel

A crucial suspension parameter.
This defines the vertical travel limits for each axle—how far it can move up and down.
Higher values create a softer suspension; lower values make it stiff and less forgiving over bumps.

⸻

11. powered_axle

A true/false list indicating which axles receive power from the engine.
For example, a typical 6×4 truck uses:
false, true, true
meaning only the rear two axles are powered.

⸻

12. kerb_weight

Defines the static weight applied to each axle when the truck is empty.
It affects handling, braking stability, and how the suspension behaves during acceleration and cornering.
Incorrect values can cause unrealistic physics.

⸻

13. liftable_axle

A true/false list showing which axles can be lifted.
Liftable axles help save fuel and reduce tire wear when the truck is not carrying heavy loads.

⸻

14. steerable_axle

Defines which axles are steerable.
Steerable axles improve turning radius and maneuverability, especially on multi-axle trucks.

⸻

15. sounds

This section maps FMOD sound events to chassis-related actions—
such as air brake noises, suspension sounds, and lift-axle audio.

⸻

16. lamp_setup

Configures the truck’s lighting system, including indicators, brake lights, and auxiliary lamps.
A proper lamp setup ensures that lights behave correctly in all scenarios
