MerjTek.MonoGame.OpenVr is a library that works on WIndows to add OpenVR (SteamVR) abilities to a MonoGame project.

Help Needed

  • Fill in the different hardware OVRControllerProfiles for each VR device. This is the rAxis and ulButtonPressed information for each device.
    • Can those with various VR Hardware possibly help?
  • Finish getting the correct position and rotation information for the OVRController.

Nuget Packages

- MerjTek.MonoGame.OpenVr.DirectX v1.0.1
- MerjTek.MonoGame.OpenVr.OpenGL v1.0.1

How To Use

After Installing the Nuget Package:

    // In Game1.cs add the using statement below:
    using MerjTek.MonoGame.OpenVr;

    public Game1()
        _graphics = new GraphicsDeviceManager(this);

        // DirectX must use the HiDef profile. OpenGL can use both profiles.
        _graphics.GraphicsProfile = GraphicsProfile.HiDef; 

    // Change the Game1 base class definiton:

    // Original (From)
    public class Game1 : Game

    // Updated (To)
    public class Game1 : VrGame

    // In the Draw method
    protected override void Draw(GameTime gameTime)
        // Drawing code here
        // NOTE: The NearPlane, FarPlane, and ViewMatrix properties must be  
        // set anywhere before base.Draw is called.

        // OPTIONAL: Render the left eye to the screen
        _spriteBatch.Draw(LeftEyeTarget, Vector2.Zero, Color.White);

    // Add and implement DrawScene:

    /// <summary>
    /// Renders the scene for one eye. Will be called twice.
    /// </summary>
    /// <param name="eyeView">The view matrix adjusted per eye. (DO NOT MODIFY)</param>
    /// <param name="eyeProjection">The projection matrix adjusted per eye. (DO NOT MODIFY)</param>
    protected override void DrawScene(Matrix eyeView, Matrix eyeProjection)
        // NOTE: Implement scene drawing code here


  • Make sure you are using the HiDef profile for DirectX. OpenGL can use both the Reach and the HiDef profiles.


  • No problems building in Visual Studio 2022.
  • The nuget for OpenGL after building contains a dependency on Monogame.Framework.WindowsDX. I have to use the .nupkg editing tool to correct the dependency to Monogame.Framework.OpenGL.
