Varjo support for Unreal Engine is built on top of Unreal Engine’s built-in OpenXR support. This allows developers to create VR applications using the normal binary version of Unreal Engine without any Varjo-specific code. This works with all current generation Varjo headsets.
Some Varjo features are not supported by Unreal’s built-in OpenXR plugins. Support for these is provided in a separate Varjo OpenXR plugin, which complements the built-in Unreal plugins and enables additional features. Varjo OpenXR plugin for Unreal Engine 5 is available at developer.varjo.com and Unreal Marketplace.
See the Unreal OpenXR roadmap for more information about supported features.
You will need the following to get started with Unreal development for Varjo headsets:
- A computer that meets the system requirements for Varjo headsets
- Varjo Base 3.6.0 or newer
- SteamVR (if SteamVR™ Tracking is used)
- Unreal 5.0 or newer
- A project using DirectX 11 or DirectX 12 (Vulkan is currently not supported)
- Varjo OpenXR plugin (required to access all features)
- A Varjo headset (optional)
Follow the steps on the Getting Started page to start a new project or migrate an existing project for Varjo headsets.
For information about settings and features that are different on Varjo headsets as compared to traditional application development and other VR devices, see Recommended settings.
Developing without Varjo headset
On the Developer tools in Varjo Base page you can find information on how to test your build without a Varjo headset.
