    Hello all!

    I am currently working in Unity2020.1.0b11 on a project with the new Input System enabled (1.0.0).

    This error is in my way currently.
    Library\PackageCache\com.unity.inputsystem@1.0.0\InputSystem\Plugins\XR\XRSupport.cs(108,16): error CS1069: The type name 'InputDeviceCharacteristics' could not be found in the namespace 'UnityEngine.XR'. This type has been forwarded to assembly 'UnityEngine.XRModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' Enable the built in package 'XR' in the Package Manager window to fix this error.


    - XR & VR package was already enabled - disabling & re-enabling it makes no difference
    - NET 4.x in Project Settings
    - Changing up the Active Input Handling makes no difference
    - The DEFINES (UNITY_INPUT_SYSTEM_ENABLE_XR & VR) in Player Settings make no difference

    The project will not make use of anything XR / VR related at all.

    The only thread I can find is
    https://forum.unity.com/threads/dependency-on-the-vr-xr-built-in-packages.866182/
    Didn't help me solve my problem.

    I'd gladly embrace your ideas / potential fixes!

    If you will not be using VR or XR then try removing any VR and XR packages and disable the built-in modules(package manager builti tab).
    There are some issues with the XR/VR define but this should fix it for now

    Hi Karl,

    I am trying to write my own ActionBasedController without the XR Interaction Toolkit. I tried to define my own Input Actions and noticed that the XRHMD class is not included because it has a 
    #if UNITY_INPUT_SYSTEM_ENABLE_XR
    define.

    How can I enable this without including the XR Interaction Toolkit package?

    For now, I made a copy of the com.unity.inputsystem\InputSystem\Plugins\XR\GenericXRDevice.cs file, changed the namespace and removed the define.

    But it would be better if I could set the define somewhere with my own Interaction Toolkit

    If you enable the define without the module then you will get lots of compiler errors due to missing classes.
    You can override the defining of UNITY_INPUT_SYSTEM_ENABLE_XR through the player settings

    Thanks!

    If the XR Interaction Toolkit is not imported as a package, I cannot find, for example, "Primary 2D Axis / Left Hand XR Controller" ("<XRController>{LeftHand}/{primary2DAxis}"), when creating my own InputActions. Are these binding defined somewhere inside the XR Interaction Toolkit package?

    *EDIT*

    Why is there such a strong dependency between the XR Interaction Toolkit and the Input System?

    I would like to access the inputs from any XR device without being forced to use the XR Interaction Toolkit. You also don't do a Console Interaction Toolkit so that I can access inputs from gamepad devices.
