[Custom Build] 2017.2 RC MRTP (Windows Mixed Reality Technical Preview)


Hello Everyone,

To keep up a higher pace of changes to improve Unity’s Windows MR support we are releasing a special build of Release Candidate 2. Please only use this build if you are working on a Windows MR title otherwise use the official RC2 build which will be released soon. Note: The release notes below only cover the custom changes made on-top of RC2. These changes will be included in patch builds once 2017.2 is final.

Release Notes:

  • Improved CPU/GPU synchronization which can result in significant performance improvements for CPU/GPU bound titles.

Bug Fixes:

  • Fixed an issue which prevented Holographic Simulation or Remoting from working on Windows Fall Creators Update builds (case 952039)
  • Fixed Asserts triggering when playing a Windows Mixed Reality application in the Editor if the Mixed Reality Portal was not running (case 950519)
  • Fixed an issue that prevented Unity from updating its culling frustum if the Windows API failed to return culling data (case 927404)
  • Guarded against a potential crash if Windows Mixed Reality APIs don’t return a valid camera back buffer (case 948814)
  • renderViewportScale fixes
    • Changing renderViewportScale with anti-aliasing causes the app to freeze (case 916194)
    • Viewport scaling changes scale around the bottom-left corner instead of the center when the setting is lower than 1 (case 916192)
  • Tracking-space and tracking-loss fixes
    • Can’t set tracking-space type to Stationary (case 946305)
    • Tracking-loss screen renders badly and it shouldn’t at all on opaque headsets (case 942154)
    • Tracking loss type is not falling back to stationary when setup has not been configured (case 945163)
  • Windows MR reports incorrect grip-pose rotation (case 949198)
  • You can now correct for controller jitter by updating their poses’ information in OnPreRender (case 948954)
  • Fix for crash when toggling XRSettings.enabled off and then on again (case 952997)
  • Fix for incorrect velocity of controllers being reported relative to starting orientation instead of world origin (case 953023)
  • General lifetime and start-up fixes:
    • Fixed an issue which prevented Holographic Simulation or Remoting from working on Windows Fall Creators Update builds (case 952039)
    • Fixed Asserts triggering when playing a Windows Mixed Reality application in the Editor if the Mixed Reality Portal was not running (case 950519)
    • Fixed an issue that prevented Unity from updating its culling frustum if the Windows API failed to return culling data (case 927404)
    • Guarded against a potential crash if Windows Mixed Reality APIs don’t return a valid camera back buffer (case 948814)
    • Controllers now picked up and work in play-in-editor. Note: you may still encounter issues . Restarting the controller should fix this. (case 934611)
