NWH Vehicle Physics 2 aims to automate import process as much as possible but some actions can not be performed from scripting and so these have to be done manually.

• If the build target is Windows / x86 make sure to change it to Windows / x86_64 or Unity InputSystem will not work. This can be done under File ⇒ Build Settings. InputSystem is required for demo scenes.

Build Settings.

• A popup asking about package dependencies will pop up. Click Install/Upgrade.
• Another message will pop up after InputSystem package is done installing about disabling the old InputManager. Click No:

• Afterwards, go to project settings and change Project Settings ⇒ Player ⇒ Active Input Handling to Both. This way both Unity InputSystem and the old Unity InputManager will work (NVP2 supports both).

Active Input Handling option.

• Ignore any mesh or tree related messages that pop up in the console. These are only import related and will not show up again.
• Open the demo scene to test the import. Demo scene can be found under NWH Vehicle Physics 2 ⇒ _Demo ⇒ _Scenes ⇒ _Racetrack. The scene should work out of the box. If it does not or if you encountered any issues during import please contact the developer.
• To make the demo scene look better switch the color space of the project to Linear under Project Settings ⇒ Player ⇒ Color Space.

This asset uses Assembly Definition (.asmdef) files.

• If the project already uses assembly definitions accessing a script that belongs to this asset can be done by adding an assembly reference to the assembly definition of the script that needs asset. E.g. to access VehicleController adding a NWH.VehiclePhysics2.VehicleController reference to MyProject.asmdefis required.
  
• If the project does not use assembly definitions remove all the .asmdef files from the asset after import (not recommended!).
