0. Install and pre-check point

You have to uninstall old SDK if you have installed. You also have to update NVIDIA driver to over 390.77 (latest version when 2.6 was released).

Refer system requirements below.

Release version: Beta 2.6.0
Environment: Windows 10 64-bit (Note: Fall Creators Update is supported)
Compatible Unity versions: 5.6.0f3 and 2017.3.0f3
Firmware version: 1.41
Meta Workspace version: 1.7.0

SDK 2.6.0 Release Notes |

1. More stable tracking

As I said on the tweet, more stable image is showed on Meta2 head set. It's interesting to see 100cm size heart.

I uploaded a sample app of Meta2 SDK 2.6.

If I can use larger room, I'll try more.

2. New feature "Limited Mode"

If you activate "Limited Mode", it is similar to "Body Lock" of HoloLens. If you dis-active the mode, it is similar to "World Lock" of HoloLens.

If you enable the mode with Unity, you should check "Rotation Only Tracking" of SLAM Localizer in MetaCameraRig


But I failed to try the mode in Unity because my Meta2 keep stopping with showing "Waiting For Sensor". In this time, I used keyboard F9.

Unity editor stopped when I tried the situation below.

  • Run sample app and push F9 (Limited Mode On)
  • Moved to outbound of environmental mapping.
  • push F9 (Limited Mode Off)

I guess current Meta2 did not have a feature of realtime SLAM.

3. Other improvement & change points

3.1 Reduction of installer size

Size of older version of SDK was about 1.2GB. Size of SDK 2.6 is about 632MB.

3.2 Meta Home view is more simple and clear


Meta Home is a launcher application of Meta2. We can run three sample applications. The bottom characters of Meta Utilities, Dev Center, Shortcut were web page link.

3.2 Tutorial application was refined

3.3 Meta2 head set has no image when Meta2 app is stopped

Meta2 head set is recognized as second display by Windows10. In older SDK, expand display view (i.g. wallpaper of Windows10) was showed in Meta2 head set when Meta2 app is stopped.

3.4 Tutorial project of Unity has been published on GitHub.

4. My impression

Meta2 tracking accuracy is being improved. I found an app introduction forum.
