Note that this restart may take some time as the plugins are updated. You'll be prompted to restart the editor to complete the update. To download the updated plugin, verify that there are no conflicts in the Issues box and press Confirm. To update a plugin using the Hub, select the plugin you want to update from the list and press the Install button. Once the plugin is installed, it must be checked into source control like any other project-level plugin.

Remove Microsoft Mixed Reality plugins from your project if you no longer need them.

Keep your Microsoft Mixed Reality plugins up to date.

Discover new Microsoft Mixed Reality plugins and install them and their dependencies into your Unreal project.

You can view plugins, see their dependencies and install them into your project without leaving the Unreal Editor.

It's a new way for developers to discover and update Microsoft Mixed Reality plugins and add them to their Unreal projects. We recommend that you use the MRTK Hub to acquire MRTK plugins.

If you don't already have a mixed reality project, follow the first three sections of the HoloLens 2 Getting Started tutorials to get a project ready for the MRTK. The toolkit is intended to accelerate the development of applications targeting Microsoft HoloLens, Windows Mixed Reality immersive (VR) headsets, and the OpenVR platform. MRTK provides a cross-platform input system, foundational components, and common building blocks for spatial interactions. Mixed Reality Toolkit (MRTK) is an open-source, cross-platform development kit for mixed reality applications.

Under Target Platforms, select HoloLens 2 and click Apply. Go to the Library tab in the Epic Games Launcher, select the dropdown arrow next to Launch and click Options. We recommend installing Unreal Engine version 4.27 or 5.0 to take full advantage of built-in HoloLens support.
