Release Data

  • Release Date: May 1, 2018
  • Release Version: Beta 2.7.0.38
  • Environment: Windows 10 64-bit (Note: Fall Creators Update is supported)
  • Compatible Unity versions: 5.6.0f3 and 2017.3.0f3
  • Firmware Version: 1.61
  • Meta Workspace Version: 1.8.0 (Release Notes)

Highlights

Welcome to Meta 2 SDK version 2.7!

New firmware is available which updates your Meta 2’s display refresh rate from 60 to 72 Hz. This may not sound like a lot, but it makes everything feel snappy and reduces motion blur. You’ll swear the headset feels lighter once you update!

Additionally, occlusion is now visible in the Virtual Webcam! We hope this takes recordings of your applications to the next level!

We’ve also made countless improvements across the board, with particular focus on SLAM tracking, Hands interactions in the Unity SDK, and overall stability and performance.

Last but not least, we’ve introduced the very first version of the Meta Cloud.

We hope you like it!

SDK Component Release Notes

Please see the following links for release notes relating to specific SDK components:

Improvements

  • Firmware
    • New firmware is available! You will be automatically notified when you connect a headset which is not running the latest firmware.
      • Updates the display refresh rate on the Meta 2 to 72 Hz (the current refresh rate is 60 Hz). In addition to improving the experience of SLAM and Hands tracking, this reduces motion blur and motion-to-photon latency!
      • Improved IMU throughput, resulting in further improvements to SLAM tracking.
    • After your next firmware update, future firmware updates will be resilient to hiccups (e.g. to power outages or accidentally pulling cables) that occur while flashing new firmware onto the Meta 2.
    • Reworked firmware update application for robustness and clarity.
      • It now includes a verification step after flashing.
      • It is also capable of updating the firmware even when the current GEO and FX3 firmware is not healthy.
      • It more reliably detects when the Meta 2 is not connected via USB 3.
  • SLAM
    • Improved accuracy of SLAM tracking.
    • Enabled SLAM relocalization by default.
  • Improved surface reconstruction, including increasing the scanning resolution.
  • Virtual Webcam
    • Occlusion is now visible in the webcam. In other words, AR objects will be occluded by real-world objects in the webcam view just as they are within the headset. We hope this takes footage of your applications to the next level!
    • The RGB webcam feed has fewer visual artifacts due to improved filtering.
    • Note: In Unity applications, the window Meta2 Webcam + Holographic Overlay appears separately from the normal Unity window. See the Unity SDK release notes for more details about input focus and about using this 2D window for your own content.
  • Cloud
    • The first version of the Meta Cloud is available. You can create an account on the first screen of the Headset Setup application which runs after installation. You can also create a new account or login to an existing account by selecting the relevant option from the Utility application. Note that this account is currently independent of any existing Meta accounts. This information will be used to improve support for Meta 2 users.
  • Applications
    • The Magic Spheres tutorial application has been replaced with a little game we call “Sushi Cat.” You can launch it from the Meta Home. Keep an eye out for the corresponding tutorial, including source code and instructions explaining how we built it. We hope to share that soon, but in the meantime, don’t drop the sushi or the cat will be very sad!
    • Replaced headset fitting video with a handy quick reference guide for how to most comfortably wear the Meta 2.
    • Reworked eye calibration application. It now provides more accurate measurements of inter-pupillary distance, and it shows more clear instructions on how to best adjust the fit of the headset on all three axes.
    • Improved performance of Hands Tutorial.

Fixed Bugs

  • Improved robustness of SLAM relocalization.
  • Fixed a bug in hands algorithm that made two-handed interactions fail in certain instances.
  • Changed hands palm location calculation resulting in reduced jitter in the grabbed object position.
  • Cached diagnostics results are more reliably cleared prior to subsequent diagnostics checks.

Known Issues

  • NVIDIA graphics drivers
    • Older NVIDIA graphics drivers may not be compatible with the SDK. In particular, on certain laptops with NVIDIA graphics driver version 397.31, switching display modes from extended to direct mode required a reboot of your computer before applications can be displayed on the headset. Shortly after this SDK version was released, NVIDIA released driver version 397.64. This new driver version appears to resolve the issue.
  • Performance on machines which are below the minimum specification
    • Although we have improved SLAM tracking in this release, on computers with processors which are below our minimum specification, tracking may perform worse in this release compared to SDK version 2.6.0. If you encounter issues with tracking, please confirm via Windows’ Task Manager that your CPU usage is not at 100%. We are working to reduce system requirements in the future, but in the meantime, we recommend ensuring your computer meets the Meta 2’s minimum system requirements.
    • When running Meta applications on processors below the minimum specification, you may encounter error messages indicating issues with your Meta 2’s sensors. These errors occur because when your processor is too slow, throughput of sensor data is insufficient to produce a good user experience. If you see these messages periodically, please run the diagnostics application to confirm your headset’s hardware is working as intended, and if possible, try your Meta 2 on a more powerful computer. We plan to improve how this issue is reported in the future.
