Unity 5.4.0 Beta

5.4.0b5 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.
• Bug reporter crashes if it's opened from Finder/Explorer
• 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.
• Crash of Standalone player when character with SkinnedMeshRenderer is on the scene
• In deferred rendering, lightmapped objects affected by mixed-mode lights will fallback to forward rendering. Plan to fix this in the future by introducing baked shadow masks.
• 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: Added [ImageEffectAllowedInSceneView] attribute for Image Effects. This will copy the Image effect from the main camera onto the Scene View camera. This can be enabled / disabled in the Scene View effects menu.
• VR: Optimized Single-Pass Stereo Rendering available in Player settings

Improvements

• Editor: Added EditorSceneManager.DetectCrossSceneReferences API
• Scripting: Improved Instantiate() performance.
• UI: Begin work on improving performance of MaskUtility functions
• UI: UI now sets the texelSize for use in custom shaders
• VisualStudio: Stop using COM to launch VisualStudio for a better immediate feedback experience
• Windows Store: Improved deserialization performance when using .NET scripting backend

Fixes

• Editor: Fixed when dragging a second scene to Hierarchy the first scene would auto expand
• GI: Fix fallback to non-directional lightmaps on SM2.0 hardware
• Graphics: Fixed null reference exception being thrown when setting null to mesh triangles/indices
• Graphics: Fixed problem of being able to set syncUploadBufferSize below 2 which leads application to crash on startup
• MonoDevelop: Disabled Git, Subversion and NUnit add-ins by default. Fixes issue with being unable to write to newly created scripts
• MonoDevelop: Fixed issue with MonoDevelop showing "��u" symbols in document view after using "Save As"
• MonoDevelop: OSX: Fixed issue with MonoDevelop not working when copied to case-sensitive partition
• MonoDevelop: Show hint in breakpoints dialog that explains exceptions list is generated from currently selected project
• Scripting: GetTransform<>() invoked from a constructor or field initializer could crash Unity.
• Shaders: Fix DX11 shader disassembly not showing correctly in the editor UI for 'show compiled code'.
• UI: All struct value types now use iEquatable to prevent memory allocations
• UI: Changed Canvas scaler to only scale the XY and not the Z of the transform
• UI: Fix for 1/2 pixel offset not working on screen-space camera canvases
• UI: Fix issue where setting canvas scaller to zero would cause a out of memory exception
• UI: Fixed issue where text glyphs would be truncated if any texture filtering occured.
• UI: Fixed issue where UnityEvent wouldn't allow the removeal of events after reload
• UI: Fixed issue with Masking when enabling and disabling graphics
• UI: If the mask is disabled we should use the baseMaterial instead of the masking material
• UI: If the UI shader is not found the default "pink" shader will be used
• UI: Make sure FontUpdateTracker get called for tracking fonts changed in the inspector
• UI: Make sure InputEvents are sent when IME composition strings are updated in Windows Standalone.
• UI: Prevent null list from geting passed as a parameter for VertexHelper functions
• UI: Remove special case ascent calculation for non-dynamic fonts
• UI: The UI batching grid size is not deterministic based on canvas/ element size.
• UI: UI overlay canvas's will now always be drawn ontop in the scene view.
• UI: Use GetRayIntersectionAll in Physics2DRaycaster to get more accurate results.
• UI: When updating rectTransform data make sure comarisons are against old value not the set value
• VR: Exposed Camera.targetEye to script for Virtual reality Applications.
• VR: Fix Screen Orientation on GearVR applications.
• VR: Fixed Splash Screen Aspect ratio issues for VR Applications.

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

Improvements

• Graphics: GPU Instancing: Added #pragma instancing_options for specifying instancing-specific options. Currently maxcount is the only option which allows the max batch size (i.e. the array size of the instanced properties) to be configured.
• Graphics: GPU Instancing: Surface shader now supports instancing by simply adding #pragma multi_compile_instancing directive.

Fixes

• Analytics: Fixed Analytics fails to start on clean install
• Animation: Fixed a bug where Light.m_Enabled didn't animate properly when using AnimationComponent
• Editor: Fix CaptureScreenshot in editor and screen-capturing for Unity Remote
• Editor: Fix the issue that SceneManager.sceneCountInBuildSettings gives 0 until entering play mode
• Editor: Fixed the issue that calling SceneManager.LoadScene** while exiting playmode causes scene unremovable from the hierarchy
• Editor: Make sure persistent transforms are not added to the active scene when running in a player. This could happen if a prefab is loaded from Resources
• GI: Enlighten. Unity crashes if scene is unloaded before it gets a chance to fully load
• Graphics: Fixed GPU Instancing now working with Graphics.DrawMesh.
• iOS/IL2CPP: Prevent a managed exception on 64-bit builds during some array creation operations which has the message "ArgumentException: Destination array was not long enough. Check destIndex and length, and the array's lower bounds".
• Profiler: Fixed missing Worker threads data from Timeline Profiler
• Renderdoc: When making a RenderDoc capture from editor UI, make sure to include the whole frame including user script updates.
• Shaders: During surface shader generation, do not initialise non-vector type members of the Input struct i.e. a struct/int/matrix as a member variable of the Input struct
• Shaders: Fixed a shader compiler crash if a compute shader declares a samplerstate that doesn't match the naming scheme.
• Shaders: When changing shader hardware tier emulation, only reload shaders (not textures/RTs) to stop refl probes breaking.
• Shadows: Change light shadows near plane minimum bound to either 1% of range or 0.1, whichever is lower.
• tvOS: Fixed Apple TV inclusion into Mac and Windows installer sets
• Windows Store: Fixed a "MdilXapCompile failed" error when trying to build Visual Studio project for Windows Phone 8.1. This used to happen when the Unity game had over 8000 classes across all assemblies.
• Windows Store: Fixed a crash which happened on "Windows N" versions when using IL2CPP scripting backend.
• Windows Store: Fixed an issue which caused small tiles get copied to Visual Studio solution incorrectly for Windows Phone 8.1 SDK.
• Windows Store: Fixed Application.Quit() when using D3D project type or IL2CPP scripting backend.
• Windows Store: Fixed error "Task 'ExpandPriContent' failed." which occurred when trying to build an application package with IL2CPP scripting backend when using default Unity icons.
• Windows Store: Fixed Visual studio graphics debugger crashing when trying to debug Windows Phone 8.1 projects.
