Oculus Integration for Unity - 1.40
Unity provides built-in VR support for the Oculus Rift, Oculus Quest, and Oculus Go. The Oculus Integration for Unity 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, advanced rendering features, object-grabbing and haptics scripts for Touch, debugging tools, and more. For more information, see our Unity Getting Started Guide.
The Oculus Integration for Unity is available in the Unity Asset Store. Download the package from the Oculus Integration page, or by searching for Oculus Unity Integration in the Asset Store tab of the Unity Editor.

New Features
- Updates to the Mixed Reality Tools package.
- Added Late Controller Update to OVRManager. pdates the pose of the controllers immediately before rendering, for lower latency between real-world and virtual controller movement.
- Updated the behavior of Use Recommended MSAA Level in OVRManager. This setting is now enabled by default.
OVRDisplay.RecenteredPose: Is now supported on Quest. The event is sent anytime a user recenters.- Removed the requirement to manually generate an AndroidManifest.xml file with the headtracking manifest flag for Oculus Quest support. Simply adding "Oculus Quest" to the list of target devices in OVRManager will update the manifest file.
Integration Changes
- Updated the Oculus Unity Integration to 1.40, including:
- Updated the Audio Spatializer to 1.40
- Updated the Lipsync integration to 1.40

Version-Specific Known Issues
This section details known issues with supported versions of Unity.
Unity Version | Known Issues |
|---|
2018.2 | All Unity 2018.2 versions - (Mobile) You'll need to either switch the AndroidBuildSystem to internal or export a Gradle project and modify the SigningConfig in the build.gradle file to include v1SigningEnabled=true, v2SigningEnabled=false.
2018.2.20f1 - (Mobile) Some game objects may appear darker when loaded in 2018.2.20f1. To work around this issue, load the project in another version of Unity, like 2018.2.19.

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 | - The Vulkan API is not currently supported for Oculus development on Unity. You may need to remove "Vulkan" from the "Graphics APIs" list in Player Settings if you receive build errors in the Unity Editor.
- 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.
|
|---|
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.
- For Mixed Reality Capture, ZED Camera users should upgrade their SDK version to 2.3.1 or later. Previous versions are not compatible.
|
|---|
Mobile | - A known bug in Unity causes a deterioration of performance in mobile applications when the back button is used to enter the Universal Menu and then to return to the application. It particularly affects applications that use multi-threading or which have high CPU utilization, and S7 (Europe) and S8 (global) phones. This bug is fixed in Unity versions 2017.3.0b9 , 2017.2.0p3, 2017.1.2p4, and 5.6.4p2.
- Do not use Utilities 1.11.0 due to a crash when returning to focus from Universal Menu or Quit to Home dialog.
- When Single Pass Stereo rendering is enabled, building projects will fail with the error message “Shader error in 'Mobile/Bumped Detail Diffuse'” in certain cases. For more information, see “Known Issues” in the Single Pass Stereo Rendering section of Advanced Rendering Features.
- (Gear VR) Flickering or left/right eye mismatching can occur when you have an input attribute value pass through to a pixel shader directly on Mali GPUs such as those in Samsung phones (used in Gear VR HMDs). This is because the ARM driver specifically targets such "volatile" data and tries to optimize for it, inadvertently creating the issue. A workaround is to try to use a modified version of the original value in some way. For example, instead of passing input value a directly through to shader value b, set b = a + 0.0001; which will prevent the driver from treating b differently.
