5.4.0b6 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.
  • Changing the active graphics API in the Editor while a Canvas is in the scene will crash the Editor. As a workaround, open only a new, empty scene before changing graphics API.
  • Graphics: a deadlock might happen in very rare cases in the PrepareShadowMaps.
  • Graphics: with the new jobs enabled, reflection probes might render incorrectly in rare cases.
  • In deferred rendering, lightmapped objects affected by mixed-mode lights will fallback to forward rendering.
  • Saving a scene on OSX might throw the error in the console: "TLS Allocator ALLOC_TEMP_THREAD..". Happens only on OSX El Capitan (10.11.1). Doesn't happen on OSX 10.10;
  • Shadows: Directional shadows will present shadow acnee when using a custom projection matrice and a very large frustum (20k+)
  • Unity crashes sometimes after deleting asset files from project folder
  • [Billboard][LOD] Unity crashes when picking deleted Speedtree Billboard LOD level
  • [GL] [Windows] Unity crashes or hangs with no respond on moving and undocking tabs
  • [MonoDevelop] "..UnitTestTextEditorExtension not found.." error message appears when user open script in MonoDevelop
  • [Skinning] Skinning broken on Mac
  • [Windows][MT] Unity crashes after mass placing SpeedTrees on terrain

Features

  • Graphics: Graphics jobs can now be enabled (see player settings) for a potential performance boost. Currently in experimental status due to unknown project-dependent side effects.
  • Web: WebPlayer support has been removed

Changes

  • Scripting: Renamed onSceneLoaded to sceneLoaded, onSceneUnloaded to sceneUnloaded and onActiveSceneChanged to activeSceneChanged to be compliant with naming conventions

Improvements

  • Installer: DownloadAssistant will warn users if they try to install components which require Unity, without selecting UnityEditor component
  • Installer: WindowsEditor Installer will install Release Notes internet shortcut to the windows start menu
  • Particles: Added option to select exactly which UV channels the Texture Animation Module is applied to
  • Particles: Support choosing a random start frame in the Texture Animation Module
  • Substance: A FreezeAndReleaseSourceData() method was added to the ProceduralMaterial class. This renders the ProceduralMaterial immutable and releases some of the underlying data to decrease the memory footprint. To release even more of the underlying data, it is necessary to call Resources.UnloadUnusedAssets() afterwards. Once frozen, the ProceduralMaterial cannot be cloned, its ProceduralTextures cannot be rebuilt, nor its inputs be set.

Fixes

  • Android: Support OpenGL ES 3.0 on Vivante GPUs
  • Animation: Fix import of humanoids when root object rotation is not identity. Mostly single root 3DSMAX models
  • Core: Fix for prefabs not updating the root order property modification under certain circumstances.
  • Editor: Fix scene view crash if internal scene view camera is disabled
  • Editor: Show a warning in camera inspector when it wants deferred but is set to ortho
  • Editor: [PlayerSettings] After changing Graphics API some UI elements do not respond correctly
  • Graphics: DX12: Implemented support for ShadowSamplingMode.
  • Graphics: Filter out duplicate graphics APIs in PlayerSettings.SetGraphicsAPIs
  • Particles: Ensure no garbage is generated when using some script commands
  • Particles: Fix case of scale not being applied correctly to AABB in the TrailRenderer
  • Particles: Fix crash when mesh is missing inside player (eg a default mesh is used)
  • Particles: Fix error message when particles have zero velocity and start inside a collider
  • Particles: Fix particle shader preview to display a flat plane instead of a sphere
  • Particles: Fix stretch particle bounds to avoid culling errors
  • Particles: Fixed mesh double scaling issues
  • Particles: Fixing collision events to ensure correct events are sent to correct gameobjects
  • Particles: Give subemitters better default names, based on their context (birth, death etc)
  • Particles: LimitVelocityOverLifetime module shouldn't allow negative values
  • Particles: Max Collision Shapes option cannot be negative
  • Particles: Reverse 3D rotation direction, for consistency with existing 1D rotation
  • Scripting: Debug.Log won't consume memory when StackTraceLogType is None
  • Substance: Fixed corner cases of outputs not being impacted by any input not being generated

The following are changes and fixes to 5.4.0 features and regressions...

Improvements

  • Graphics: Add -force-metal switch to force Metal rendering on OSX/iOS

Fixes

  • 2D: Occlusion Culling to work correctly with X/Y flipped SpriteRenderers
  • Animation: Fixed an issue with RectTransform not being animatable
  • Bug Reporter: Fixed bug reporter if it's opened from Finder/Explorer
  • Core: Deprecated Random.seed. Introduced new API to properly expose full internal state of the RNG through Random.state. The RNG state can now be initialized with Random.InitState()
  • Editor: Fixed crash when entering playmode if a user script would load a new scene in Awake
  • Graphics: Fixed command buffer DrawMesh not working if Mesh was not uploaded to VRAM before
  • Graphics: Fixed occasional crash when switching editor from DX11 or loading RenderDoc
  • iOS: Fixed crash triggered by deactivating an input while app is going into background
  • iOS: Fixed redirect for WWWConnection
  • iOS: Fixed WWWConnection deadlock.
  • iOS: Moved callback methods to another thread as to not block main thread when streaming assets
  • iOS: Notify Transport that we finished recieving data so we can mark the buffer as complete when we get an error
  • JsonUtility: Fixed crash when serializing very large arrays/lists
  • OpenGL: Fixed crash on compute shader linking failure.
  • Particles: Crash fix when using disabled component in TriggerModule
  • Particles: Fix crash due to bad data alignment when using sub emitters
  • Particles: Fix terrains not using layer filtering for particle collisions
  • Particles: Fixed SIMD alignment issues causing asserts/crashes
  • Particles: Reintroduced support for negative inherit velocity values
  • Serialization: Fixed crash in JsonUtility when deserializing arrays of classes or structs on .NET scripting backend
  • Shaders: Fixed a potential editor crash if shader compiler failed to disassemble a shader.
  • Shaders: Fixed an editor crash on shutdown if the shader compiler had previously crashed
  • VR: Fixed VR rendering not displaying the right eye.
  • Windows Store: Fixed antialising when calling Screen.SetResolution on Universal Windows 10 Apps
  • Windows Store: Fixed plugins that are marked are only UWP compatible to be only included in UWP builds
  • Windows Store: Screen.Resolution(, , true) will no longer ignore width and height, so you can set your desired resolution on Universal Windows 10 Apps
