Add-ons

Third-party integrations and extensions for NWH Vehicle Physics 2.

Unity DirectInput

Force feedback steering wheel support via DirectInput. Provides physics-based steering torque with configurable per-vehicle settings.

Features:

  • Self-aligning torque calculation from wheel physics
  • H-shifter and sequential shifter support
  • Customizable force feedback coefficients per vehicle
  • Power steering simulation
  • Secondary effects (suspension bumps, engine resonance, weight transfer)

Setup:

  1. Install Unity-DirectInput package
  2. Import DirectInputFFB Sample from Package Manager > NWH Vehicle Physics 2 > Samples
  3. Add DirectInputManager and FFBInputProvider prefabs to scene
  4. Configure wheel device mappings and calibration

For detailed configuration, see the DirectInputFFB Sample documentation included with the sample.

Vehicle Noise Synthesizer

Vehicle Noise Synthesizer

Open-source audio addon for granular engine sound synthesis without external dependencies like FMOD.

Features:

  • RPM-based sound synthesis
  • No middleware dependencies
  • Free and open source

Created by imDanoush. Visit the Vehicle Noise Synthesizer repository for setup instructions and updates.

Audio Middleware

NWH Vehicle Physics 2 uses Unity's built-in audio system with Audio Mixer for routing and effects. For FMOD or Wwise integration, custom sound components can be created by extending SoundComponent base class.

See SoundManager and SoundComponent documentation for implementing custom audio solutions.
