Main Features

_____________________________________

Easy and fast to set up using the VehicleSetupWizard. Turn a model into a drivable vehicle in under 30 seconds.
Modular vehicle architecture. Enable or disable parts of the vehicle as they are needed, either manually or through the in-built LOD system.
Efficient, stable, and highly accurate powertrain solver ensures realistic vehicle behaviour.
Fully adjustable at runtime – modify suspension, friction, gearing, powertrain, and more, giving you total control over vehicle behavior in real-time.
External module system. Add or remove functionality as needed. Modules are easy to write and can modify almost any part of the vehicle's behavior.
Wheel Controller 3D (https://assetstore.unity.com/packages/tools/physics/wheel-controller-3d-74512) is included as the default for enhanced 3D ground detection, offering more realistic handling, better adjustability, and a strong alternative to Unity's WheelCollider.
Vehicle switching using VehicleChanger with 1st person enter/exit functionality, allowing you to switch between cars, boats, and aircraft within the NWH Physics World.
Per-wheel surface detection. Different friction curves, sounds, and effects for each surface.
Easily extendible interface-based input system with support for Input Manager, Input System, Rewired, steering wheels, and mobile controls.
Custom editors for all scripts make navigation through the asset easy. For this we developed NUI, an editor GUI framework, to keep the visual experience through the whole asset consistent.
Support for 'Photon Unity Networking 2' and 'Mirror' multiplayer solutions.
Highly optimized code ensures smooth performance across both desktop and mobile devices.
Everything seen in the demos is included in the package.
Full C# source code included.

Physics Features

_____________________________________

Realistic powertrain model based on inertia, torque, and angular velocity, offering dynamic and authentic vehicle behavior, such as rolling starts and engine stalling.
Engine with adjustable power curve, losses, rev limiter, forced induction (turbocharger or supercharger), and simulated fuel consumption (module). The engine can be stalled. Support for ICE and electric engines/motors.
Clutch can be either manual or automatic, with adjustable slip torque and engagement. Releasing the clutch too fast will stall the engine.
Transmission can be Automatic, Automatic Sequential, Manual, CVT, or External. Realistic gear ratios with adjustable shifting behavior make it suitable for any type of vehicle. Shift duration, variable shift points, incline effect, etc. are all adjustable at runtime. Supports an unlimited number of forward and reverse gears.
Differentials - Open, Locked, LSD, or External. Any number and configuration of differentials are possible, be it FWD, RWD, AWD, 6×6, 8×8, etc.
Wheels and Suspension are handled by WheelController3D which not only gives them 3D ground detection but also makes them highly adjustable. Spring and damper curves with bump and rebound damping, adjustable spring curves for progressive suspension, camber, anti-squat geometry, rim offset, inertia, drag, surface friction presets using modified Pacejka or completely custom curves, individually adjustable longitudinal and lateral friction, load/grip curve, adjustable ground detection resolution, etc.
Axles - each axle can have one or more wheels. Each axle has adjustable steering (steer coefficient, Ackerman, toe angle), adjustable brake and handbrake strength, caster, and camber angles. Solid axles are supported.

Sound and Effects

_____________________________________

Damage affects vehicle performance and handling. Optimized queue-based mesh deformation that spreads processing over multiple frames.
Sound system with 15+ effects and automatic AudioSource setup, requiring no manual intervention at runtime.
Persistent, surface dependent, procedural mesh skidmarks.
Vehicle lights with low beam, high beam, tail and brake lights and blinkers supported. Can be used with any number of lights of any type and/or emissive materials.
Surface particle effects that are set up automatically and depend on the surface type.
Exhaust smoke and exhaust flames.

Input

_____________________________________

Support for the following input methods out of the box:

Input Manager
Input System (demo default)
Rewired
Mobile (on-screen) input
Steering wheel input (with configuration for Logitech G29)

Input is handled through a custom InputProvider system which makes implementing custom input methods simple.

Cameras

_____________________________________

Flexible camera changing system that works with any camera script, including Cinemachine.

Multiplayer

_____________________________________

Mirror and PUN2 support out of the box.
Vehicle state that can be transferred through a single struct makes custom multiplayer implementations easy.

Modules

_____________________________________

Module system makes adding extra functionality to the fast and easy, with the code being similar to that of a typical MonoBehavior with familiar functions such as Update() and FixedUpdate().
Following modules are included:

Motorcycle
Arcade
ABS
ESC
TCS
Aerodynamics
NOS (boost)
Cruise Control
Flip Over
Fuel
Metrics
Rigging
Speed Limiter
Trailer + Trailer Hitch
Air Steer

Compatibility

_____________________________________

Officially compatible with:

Rewired
Complete Terrain Shader (CTS)
IK Avatar Driver
Mirror
Photon Unity Networking 2

Notes
