Oculus Utilities for Unity Release Notes 1.20.0

Unity versions 5.1 and later provide built-in VR support for the Oculus Rift and Samsung Gear VR. The optional Utilities unitypackage includes prefabs, C# scripts, sample scenes, and more to assist with development. For more information, see our Unity 5 Developer Guide.

The Utilities package includes the most recent version of the Oculus OVRPlugin that is also included in the Unity Editor. When you import the Utilities package into a project, if the OVRPlugin included with Utilities is greater than the version in your Editor, a pop-up dialog will give you the option to update it. We recommend always using the latest-available OVRPlugin version.

Note: the latest OVRPlugin version number may be a version or two behind the Utilities version number.

2017.1 and 2017.2 are officially supported, and we recommend developers update to these versions when convenient. Our support for 2017.3 is currently in beta, and we do not recommend shipping applications using it at this time.

For information on which versions of the Unity Editor are compatible with which versions of Utilities for Unity, please see Compatibility and Version Requirements.

Be sure to review our Downloads page for other useful tools to assist development, such as the Unity Sample Framework. For more information on Oculus resources for Unity developers, please see Other Oculus Resources for Unity Developers.

The Oculus Integration, available through the Unity Asset Store, provides several unityPackages in a single download, including our Utilities for Unity, Oculus Platform SDK Unity plugin, Oculus Avatar SDK Unity Plugin, Oculus Native Spatializer Plugin, and the Unity Sample Framework.

Bug Fixes

  • Fixed regression of MRC sandwich composition in Unity 5.6.1p2 in which the foreground output was missing.

Known Issues

  • Do not use Utilities 1.16.0-beta. If you are using that version, please update to a later version.
  • Unity 5.6 versions 5.6.3p2 and later, and Unity 2017.1 versions 2017.1.0p3 and later:
    • The Unity engine uses projection matrix calculations that are at variance with the Oculus SDK, causing VR scenes to have the wrong parallax, which may cause discomfort. Note that object size in affected scenes is not quite correct, and take this into consideration when thinking about design. We are working with Unity to fix this as soon as possible.
  • 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.
  • Cubemap VR compositor layers currently do not work in mobile applications, or in Rift applications using Unity versions earlier than 2017.1.
  • Adaptive Resolution currently works only with Unity 2017.1.1p1 and later.
  • Unity 5.6 and later: If you have updated your OVRPlugin version from Utilities, you may see a spurious error message when the Editor first launches saying “Multiple plugins with the same name 'ovrplugin'”. Please disregard.
  • 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.
  • Rift
    • All Unity versions prior to 5.4.3p3 leak 5MB/s if you have a Canvas in your scene, enable Run In Background, and dismount the Rift. You can check OVRManager.hasVrFocus in an Update function to disable your Canvases while the HMD is dismounted.
    • Transparent VR Compositor Layers do not currently support multiple layers of occlusion.
    • The following versions of Unity require the Visual C++ Redistributable for Visual Studio 2015 or Rift builds will fail to run in VR, and the error “Security error. This plugin is invalid!” will be reported in output_log.txt:
      • 5.3.6p3-5.3.6p7
      • 5.4.0f1-5.4.2p1
      • 5.5.0b1-5.5.0b8
  • Gear VR
    • Unity 2017.2/OVRPlugin 1.18.1: GetActiveController switches to gamepad following Gear VR Controller button release.
    • Mobile developers should not use Unity versions 5.3.6p1-2 and 5.4.0p1-2 due to incorrect positional movement of the head.
    • Unity 5.3.4-5.3.6p3 and Unity 5.4.0b16-Unity 5.4.0p3: Do not set DSP Buffer Size to Best in Audio Manager in the Inspector for now or you will encounter audio distortion. Set it to Good or Default instead.
    • Gear VR applications built with Unity 5.6.0f2 crash immediately upon launch, and Gear VR applications built with 5.6.0p1 may crash when Multi-View is enabled.
    • A known bug in Unity 2017.x 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 use high CPU utilization, and S7 (Europe) and S8 (global) phones.
    • Do not use Utilities 1.11.0 due to a crash when returning to focus from Universal Menu or Quit to Home dialog.
  • Single-Pass Stereo Rendering
    • When Single Pass is enabled, building mobile 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.
    • Two graphics driver issues affect mobile applications with Single Pass enabled using some S8 or S8+ phones with Unity 5.6.0p2-3. They can occur when Standard Shader Quality is set to low, or when you are using tree objects. For more information and workarounds, see “Known Issues” in the Single Pass Stereo Rendering section of Advanced Rendering Features.
