5.4.0b10 Release Notes

Known Issues

  • After expand/collapse Unity Editor window looks corrupted. If you maximize/minimize/click on windows in Editor they'll return to normal state.
  • Android: UI Input requires two touches to work
  • Crash in ::RenderGameViewCameras:: after overflowing Width or Height fields of the Game view resolution window
  • First launch of Unity on new computer doesn't create "~/Library/Unity/Packages" folder, blocking homescreen from loading. Second launch will fix the issue
  • GPU Instancing: Instancing might get broken under glcore if graphics jobs are enabled.
  • In deferred rendering, lightmapped objects affected by mixed-mode lights will fallback to forward rendering.
  • On Windows with MSAA and Image Effects, game view can be rendered upside down.
  • Shadows: Directional shadows will present shadow acnee when using a custom projection matrix and a very large frustum (20k+)
  • Using OpenVR + Vive + Outdated Oculus Utils = Crash. Users are advised to update their Oculus Utils.
  • VR: Image effects do not currently work with single pass rendering.
  • VR: Single-Pass-Stereo causes some lighting problems
  • VR: Some built-in shaders do not currently work with single pass rendering resulting in wrong transformations in right eye. Workaround is to manually include the shaders in your project.
  • With Webplayer removal, desktop players are now part of their respective editor installations. Thus the option to separately install them is removed.
  • [Billboard][LOD] Unity crashes when picking deleted Speedtree Billboard LOD level
  • [IMGUI][OSX] Detached tab is not moved slightly with the cursor after opening project with changed layout in 5.4.


  • Global Illumination: When compositing the directional lightmap removed the clamping on the w-component of the generated pixels.
  • Particles: Added particle radius parameter for world collisions.


  • Android: Audio - Don't select OpenSL output if the native device params are too bad for fast path (fixes audio issues on buggy devices)
  • Android: Buildpipe - Updated SDK tools requirements for the Editor
  • Android: Editor - Added Marshmallow to the list of APIs
  • Android: IL2CPP - Use Android NDK x64 on x64 Windows Editor
