Oculus Integration for Unity - 20.1

Unity provides built-in VR support for Oculus devices. The Oculus Integration package adds scripts, prefabs, samples, and other resources to supplement Unity’s built-in support. The package includes an interface for controlling VR camera behavior, a first-person control prefab, a unified input API for controllers, rendering features, debugging tools, and more.

For more information about setting the development environment, go to Get Started with Oculus in Unity.

Download Oculus Integration Package

The Oculus Integration package, OculusIntegration.unitypackage, is available for download from the Unity Asset Store and on the Unity Integration Archive page.

Before you import the package in unity, check the hardware, software, and Unity version requirements. The minimum supported Unity Editor version for Oculus development is 2018.4.

What's New

Added support for Oculus Quest 2 as a target device.
Added OVRManager.systemHeadsetType() to return the headset type.

Note: You may encounter issues when running ARM7 build on Oculus Go or Oculus Quest, if you are using Unity's XR Management system with the latest OVRPlugin and the Oculus XR Plugin is outdated. In such case, you can either switch to ARM64 build, or upgrade the Oculus XR Plugin to 1.4.0+ to fix the issue.

General Unity Known Issues

This section details known issues with Unity that are not tied to a specific version. Issues are grouped by most closely related subject.

Subject	Known Issues
Unity	Vulkan Quest apps might crash when you select Use Recommended MSAA Level in OVRManager and request audio permissions after the splash screen runs. To overcome this issue, clear Use Recommended MSAA Level check box in OVRManager and manually set the appropriate MSAA level (recommended 4x) in Project Settings > Quality. Changing modes in Lipsync_Demo on Oculus Quest is currently not supported. Unity has a known issue such that parenting one VR camera to another will compound tracking twice. As a workaround, make them siblings in the GameObject hierarchy. Using Unity Universal Render Pipeline will not set the MSAA level automatically.
Windows 10	If you experience long UI stalls or poor performance with the Unity Editor when targeting Rift on Windows 10, please run Windows Update to ensure that you have the latest version of Windows 10. All Unity versions with Oculus runtime 1.17+ and Windows 10 + Creators Update: This combination results in spurious WM_DEVICECHANGE reports in the editor, even in non-VR projects. Many users will notice no impact, but users connected to certain USB devices may find the Editor becomes non-responsive and needs to be terminated from Task Manager. To mitigate, please update to the Beta runtime available on our Public Test channel. We are currently working with Unity and Microsoft on a permanent solution.
Rift	Guardian System API: ovr_SetBoundaryLookAndFeel currently does not take effect if the HMD is not worn when the call is made (e.g., on Start). Transparent VR Compositor Layers do not currently support multiple layers of occlusion.
