2017.3.0f1 Release Notes (diff since 2017.3.0b11)

Known Issues in 2017.3.0f1

• Android: Gradle builds fail when there are more than 250 files in streamingAssets. As a workaround, you can use a custom file extension for the files you want uncompressed. Specify this extension in a custom Gradle mainTemplate under "noCompress". You should also remove "STREAMING_ASSETS" from the template to avoid hitting the file limit. (962451)

• Universal Windows Platform: [WSA]Unity throws a System.IO.DirectoryNotFoundException error when exporting to the WSA player (UWP/.NET Backend) with a Project folder that has a long path. (959984)

• XR: [Android] Unity throws an exception while initializing GoogleVR from the Unity library using the Gradle build system. (946104)

2017.3.0f1 Release Notes (Full)

Features

• Analytics: Added support to capture VR device refresh rate, dimension, aspect ratio, HMD tracking and Controllers tracking as part of device info and device status events.

• Animation: Added support for integer and enum animation.

• Asset Pipeline: Added AssetDatabase.ForceReserializeAssets API. This method allows you to proactively load, upgrade, and write back to disk any Asset or Scene files in the project. When project upgrades cause serialization changes to Assets and metafiles, Unity writes these changes to disk separately from regular development iterations.

• Editor: Added assembly definition files for script compilation pipeline in the editor. This allows you to define your own managed assemblies based on scripts inside a folder. Splitting your project's scripts into multiple assemblies can greatly reduce script compilation times in the Editor. Note that the latest version of Visual Studio Tools for Unity is required for this feature to work with solution and project generation for Visual Studio.

• Editor: Added events: MouseEnter, MouseLeave, MouseOver, MouseOut, AttachToPanel, DetachFromPanel, PostLayout.

• Editor: Added Focus events that notify UIElements when they gain or lose focus (the focused element receives keyboard input), and a focus ring, which is a circular list of UIElements that gives the order in which they receive the focus when you press Tab or Shift+Tab.

• Editor: Added the Transform Tool, a single Gizmo you can use to move, rotate and scale in the Unity Editor.

• Editor: You can now use DX12 API in the Editor.

• Facebook: Segmented the uploader for the Facebook platform.

• GI: Added support for HDR compressed lightmaps (BC6H) on PC, Xbox One and PlayStation 4. To enable this, go to Player Settings and set the Lightmap Encoding option to High Quality.

• Graphics: Added a new method, ScreenCapture.CaptureScreenshotAsTexture. Use this to save screenshots taken with ScreenCapture as Textures in the Editor.

• Graphics: Added Crunch compression support for ETC_RGB4 and ETC2_RGBA8 textures. Improved compression ratio and speed for DXT Crunch.

• Graphics: Added Dynamic Resolution as an engine feature, debuting on Xbox One platform.

• Graphics: Added support for multisampled Textures in Shaders. To use a multi-sampled Texture in a Shader, declare it as Texture2DMS (or, for example, float for a single-channel texture), and then sample as described in Microsoft's documentation on Texture2DMS::Load methods. You must create the corresponding RenderTexture with the bindMS flag set on the RenderTextureDescriptor, or set the bindTextureMS flag after creation on the RenderTexture itself.

• Graphics: Support for 32 bit Mesh index buffers:

  • By default, meshes larger than 65k vertices get imported with a 32 bit index buffer. Smaller meshes still use 16 bit indices.
  • Added Index Format setting to Mesh Importer to override this behavior.
  • Added Mesh.indexFormat to scripting API for Meshes created at run time.

• Kernel: Added new argument -systemallocator. This disables Engine management of allocations, and instead uses system allocations. This is useful when using external tools for memory debugging.

• Particles: Added a new Speed Modifier option in the Particle System Velocity Module. Use this to control particle speeds without changing their directions.

• Particles: Added Unlit and Surface shaders for use with Particle Systems.

• Particles: Ribbonized Particle Trails.

• Physics: Exposed a new broadphase algorithm called called Multi-Box Pruning, which is based on subdividing the world boundaries. This helps to overcome the performance issues in the standard sweep-and-prune approach, by exluding the excess checks of bodies that are far away but overlap each other along one of the principal axes. Access Multi-Box Pruning in the Unity Editor's Physics Settings.

• Physics: Exposed new settings in the Physics Manager: Contacts Generation, Contact Pairs, and Broadphase Type. This allows receiving the collision and trigger events from kinematic-kinematic and kinematic-static contact pairs.

• Physics: Exposed MeshCollider.cookingOptions. Cooking options allow you to enable or disable certain features in Mesh cooking (the process of turning a normal Mesh into a Mesh that is suitable for use in the physics system). These options can help you achieve a much shorter cooking time. This API requires that you manually check the input data for validity.

• Playables: Added new delay feature for IPlayables.

• Playables: Added new Video Playables Integration.

• Profiler: Added API for custom threads profiling: Profiling.BeginThreadProfiling, and Profiling.EndThreadProfiling.

• Scripting: Added command line option "overrideMonoSearchPath" for desktop standalone players (OSX, Windows). "overrideMonoSearchPath" specifies an extra folder to search when Mono is loading assemblies. One intended use is to have two versions of the same project (such as a trial version and a full version). The Assets are the same, but the scripts are different. You can use this command line option to re-use the Assets, but load different scripts.

• Scripting: Added Mono/.NET 2.0 support for Memory Profiler. See more on GitHub.

• Services: Performance Reporting Service: Added support for MacOS native crashes.

• Video: Added panoramic 360/180 2D/3D video workflows.

• Video: Introduced UnityEngine.Media.MediaEncoder to expose the VideoClipImporter encoders. This allows you to create movie files via script.

• XR: Added a new option in the Windows MR Player Settings called Enable Depth Buffer Sharing. This allows the OS to better stabilize images without the need to manually set the focus plane. For more information about the benefits of image stabilization, see Microsoft's documentation on Hologram Stability.

• XR: Added new UI to Daydream VR Device configuration, to support new 6DOF Standalone devices.

• XR: Added XR support to Experimental Scriptable Render Pipelines.

• Editor: Added methods EditorGUI.EnumFlagsField and EditorGUILayout.EnumFlagsField, which respect the values of the enum type and support custom names for values 0 and ~0 (all bits set). Deprecated methods EditorGUI.EnumMaskField, EditorGUILayout.EnumMaskField, EditorGUI.EnumMaskPopup, and EditorGUILayout.EnumMaskPopup, which always assume values to be 1, 2, 4, 8 (and so on). (896176)

• Graphics: Removed allegorithmic Texture compressor.

• Graphics: Resolution is no longer clamped when using custom shadow resolution on a light, allowing you to reach up to 8k shadowmap if needed.

• Shaders: Concatenated matrix macros (e.g. UNITY_MATRIX_MVP) are now changed to static variables to avoid repeated calculations.

• Substance: Deprecated built-in support for Substance Designer materials. This support will be removed in 2018.1. To continue using Substance Designer materials in Unity 2018.1, you need to install a suitable third-party external importer from the Asset Store.

• UI: Unity no longer resets the LookDev camera when you create a new Scene. (938493)

• XR: Improved the way XR devices pause/unpause applications, particularly when pausing as a result of application focus being lost. Unity now handles overlapping pause conditions correctly, regardless of the order in which they occur.

• XR: Removed padding on double-wide texture used with Single Pass.

Improvements

• 2D: Exposed methods to set and retrieve Physics Shape from a Sprite.

• 2D: If you use Shift-Click to do picking for Tile Palette, Unity now switches back to the original tool after picking is done.

• 2D: Unity now displays a confirmation dialog box when you create new Tile Assets that overwrite existing Tile Assets.

• 2D: Unity now saves changes to the Tile Palette when you stop editing the Tile Palette, or when you save the project.

• Android: Added a new way to handle audio focus in Android Oreo.

• Android: Added the option to configure Texture decompression format on Android devices that have no ETC2 Texture format support.

• Android: Updated Gradle version and made it the default build system for Android.

• Android: [OpenGL ES] Added support for preserving the framebuffer alpha.

• Animation: Added a 2D mode to the Animation Previewer.

• Animation: Added new Translation DoFs for Arms, Legs and Head for Humanoid animation and retargeting. This converts translations (also known as stretch) found on imported animations to retargetable Humanoid animations.

• Animation: Added zoom in the Animator Window.

• Animation: Entry, Exit and AnyState StateMachine Transitions can now be copy-pasted. (921705)

• Animation: Framing a single key does not give proper context for manipulation in the curve editor, so we included neighbouring keys.

• Asset Import: Added Preserve Hierarchy toggle to the Model Importer, to prevent Unity stripping the root transform when the model has a single root.

• Asset Import: Added AssetPostprocessor.OnPostprocessMaterial.

• Asset Import: Exposed ModelImporter.MaterialLocation to allow you to switch the Iaterial import location in AssetPostprocessor scripts.

• Asset Import: Material workflow enhancement: added the ability to remap all embedded materials to existing material assets in the project, using the same heuristics as the legacy system

• Asset Import: You can now skip Video Clip transcoding during import. If you do so, Unity uses a non-transcoded version of the video instead.

• DX12: Native Rendering Plugin: Exposed and implemented native RenderBuffer resource retrieval, and fixed multithreading issues.

• Editor: Added UnityEngine.Networking.PlayerConnection.ConnectedPlayer.Name. This makes it easier for you to identify connected players.

• Editor: Connected Players now only show debug logging in Editor console, not all of stdout. Added an option to disable player logging in the Editor console.

• Editor: Fixed over 120 missing or incomplete tooltips in the Unity Editor.

• Editor: If Edit mode and Play mode tests produce files without proper cleanup, Unity now logs a warning.

• Editor: It is now possible to adjust the number of lines per log row in the Console window.

• Editor: Updated UnityShaderCompiler tool for macOS and Linux to 64bit. This improves shader compilation performance.

• Editor: You can now double-click a Scene file in the Build List to highlight Scenes in the Project view.

• Editor: You can now select which Xcode version to build your project with on MacOS.

• GI: Before, all trees, lightmap static or not, would cast baked shadows on Terrain. Now Unity honors the Static flag on the prefab.

• GI: Fixed debugging textures for GI. It's now easier to tell when they should be availble, and why they might be missing.

• GI: Legacy trees and prefabs that don't have a LOD group now cast baked shadows on Terrain. (685764)

• GI: Made spot light and point light fall-off match real-time fall-off in Progressive Lightmapper.

• Graphics: Added "base vertex" functionality to Mesh.SetIndices, to allow meshes larger than 65k vertices when using 16 bit index buffer..

• Graphics: Added GPU selection in metal for MacEditor and MacStandalonePlayer.

• Graphics: Added non-allocating overloads for GeometryUtility.CalculateFrustumPlanes.

• Graphics: GPU Instancing: Instance properties are now packed as arrays of structures. Internally, we changed the constant buffer layout, where multiple instance properties are present. There are three changes in the instancing declaration macros, but the old shaders can be upgraded automatically. For your reference, the three changes are:

  1. UNITY_INSTANCING_CBUFFER_START/END renamed to UNITY_INSTANCING_BUFFER_START/END.
  2. UNITY_INSTANCING_BUFFER_END now takes an arrayName in the parentheses.
  3. UNITY_ACCESS_INSTANCED_PROP must now be provided with the arrayName in the first argument to indicate where this property comes from. Note that if graphics jobs are not enabled, the CPU-side processing of instance property values are optimized and off-loaded to a worker thread to further reduce CPU cost.

• Graphics: GPU Instancing: Introduced a new feature on most platforms, called "flexible instancing array sizes". This means you no longer need to specify instancing array sizes. Instead, Unity calculates it from the next draw's instance count.

  • This greatly reduces shader compiling time for instancing variants.
  • If you always take the maximum constant buffer size allowed by the device, then divide by the instance data structure size, you can further reduce instance batch count, especially on OpenGL and Metal.
  • This introduces moderate performance improvements, especially for Scenes with lots of small batches. particularly useful if you rely on Unity renderloops to automatically batch instances for you.

• Graphics: Improved documentation for graphics hardware tiers.

• Graphics: Improved motion vectors precision when dynamic batching is disabled.

• Graphics: Introduced various performance and memory consumption optimizations to the Vulkan renderer.

• Graphics: Optimized Point Light real-time shadows for D3D11.

• Graphics: Updated compute shader API: Addd SetMatrix, SetMatrixArray and SetVectorArray for SetComputeXXX and for command buffer.

• Graphics: Vulkan: Implemented multidisplay support for the Vulkan rendering back-end (Windows/Linux).

2017.2.0f3 Release Notes (Full. Diff from f2 at end)

System Requirements Changes

• Removed iOS 6.0 support. The minimum supported version is now 7.0.

Features

• 2D: Added Tilemap.

• Asset Import: Added support for animated custom properties from FBX.

• Asset Import: Added support for Stingray material import from FBX.

• GI: Added per-object lightmap seam stitching for Progressive Lightmapper.

• GI: Added profiler for Realtime Global Illumination.

• GI: Added support for double-sided materials in Progressive Lightmapper. Added a new Material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other GameObjects. Backface rendering is not controlled by this setting, and backfaces are not represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.

• GI: Added support for per-object casting and receiving shadows in the Progressive Lightmapper. For "Cast Shadows", only the "On" and "Off" options are currently supported.

• Graphics: Implemented Display-P3 color gamut support for iOS and macOS. Added "Color Gamut" property to Player Settings, which will eventually cover other platforms with wide color gamut support.

• Multiplayer: Added new QoS options for delivery of large messages: reliable or unreliable, and un-ordered (fragmented) or ordered (fragmented sequenced).

• OSX: Added support for Retina in macOS standalone builds.

• Package Manager: Exposed the API for enabling internal components to be updated more frequently than the Editor. This is the first step in implementing the Unity Package Manager. We are taking an incremental approach to integrate the system into the Unity ecosystem. It will grow with more features over time. For this first release, we have avoided exposing user-facing features.

• Particles: Added "Stop Action" option to allow Particle Systems to be destroyed or disabled when they finish playing.

• Particles: Added Linear Drag support for Particles. The new options are in the Limit Velocity over Lifetime Module.

• Services: Performance Reporting Service: Added support for native crashes on Android.

• Timeline: Added support for Avatar Masks on Animation Tracks.

• Video: Added pixel aspect ratio support for non-square pixels.

• WebGL: Added linear rendering to WebGL 2.0

• XR: Added openVR support for Mac 64bit application target that use Metal graphics.

• XR: Added support for certain aspects of the Vive HMD to be simulated in-Editor without the need of a physical HMD. To enable this, use the "Mock HMD - Vive" virtual reality SDK in the Player Settings. The mock HMD uses the same asymmetric projection matrix, hidden occlusion mesh, field of view, aspect ratio, and eye texture size as the Vive. You can use mock HMD with both multi and single pass rendering paths. It renders as a split-screen stereo display in the Editor.

• XR: Added support for Google ARCore augmented reality technology when targeting Android 7.0 and above on supported devices. See our blog post for more information and how to get started

• XR: Added support for Video Async Reprojection for Daydream View. Video Async Reprojection allows an app to feed video frames directly into the Google VR Async Reprojection system without going through the main Unity render loop. This provides a fast path to direct rendering of video, regardless of the current frame rate Unity is rendering at and skips Texture filtering, providing for a much higher quality output. There is also an option to allow for the use of protected memory, for users that need to render DRM-protected content.

• XR: Added support for Windows Mixed Reality as a Virtual Reality SDK target. This extends Unity's HoloLens support so that it more generally supports Windows Mixed Reality, both for desktop and HoloLens.

• XR: Added the TrackedPoseDriver component, which can be added to a game object to match the position and rotation of a AR device, VR HMD, or VR controller.

• XR: Stereo Instancing (also known as single-pass instanced) is now supported on desktops when the DirectX 11 (DX11) rendering API is in use. Stereo Instancing is only supported with forward rendering.

• XR: Unity Editor has foundation support for EditorVR. Look for a future announcement around availability of a 2017.2 compatible EditorVR version.

• XR: Windows Mixed Reality headsets are now supported for playing in-Editor.

• XR: Introduced native integration for the Vuforia Augmented Reality Platform. Vuforia support can be installed through the Unity Download Assistant and enabled under PlayerSettings/XR. For more information about Vuforia see https://developer.vuforia.com.

Revision: cc85bf6a8a04

2017.2.0f2 Release Notes (Full)

System Requirements Changes

• Removed iOS 6.0 support. The minimum supported version is now 7.0.

Features

• 2D: Added Tilemap.

• Asset Import: Added support for animated custom properties from FBX.

• Asset Import: Added support for Stingray material import from FBX.

• GI: Added support for per-object cast and receive shadows in the Progressive Lightmapper. For Cast Shadows, only On and Off options are supported.

• GI: Per-object lightmap seam stitching for Progressive Lightmapper.

• GI: Profiler for Realtime Global Illumination.

• GI: Support for double-sided materials in Progressive Lightmapper. Added a new material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other objects. Backface rendering is not controlled by this setting nor will backfaces be represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.

• Graphics: Implemented Display-P3 color gamut support for iOS and macOS. A "color gamut" player setting has been added, which will eventually cover other platforms with wide color gamut support.

• Multiplayer: New QoS options for delivery of large messages: reliable or unreliable, and un-ordered (fragmented) or ordered (fragmented sequenced).

• OSX: Added support for Retina in macOS standalone builds.

• Package Manager: In 2017.2, we are introducing Unity Package Manager. This will be the first stepping stone for the system. We are taking an incremental approach to integrate the system into the Unity ecosystem. It will grow with more features over time. For this first release, we avoid exposing user facing features. Instead, we are exposing an API for enabling internal components to be updated more frequently than the editor (the first pillar of the system).

• Particles: Added Linear Drag support for Particles. The new options can be found in the Limit Velocity over Lifetime Module.

• Particles: Added new option to allow Particle Systems to be destroyed or disabled when they finish playing.

• Services: Performance Reporting Service: Added support for native crashes on Android.

• Timeline: Added support for Avatar Masks on Animation Tracks.

• Video: Added pixel aspect ratio support for non-square pixel.

• WebGL: Added linear rendering to WebGL 2.0

• XR: Added support for certain aspects of the Vive HMD to be simulated in-Editor without the need of a physical HMD. Enable by using the "Mock HMD - Vive" virtual reality SDK in the player settings. The mock HMD uses the same asymmetric projection matrix, hidden occlusion mesh, field of view, aspect ratio, and eye texture size as the Vive. Mock HMD can be used with both multi and single pass rendering paths and will render as a split screen stereo display in Editor.

• XR: Added support for Google ARCore augmented reality technology when targeting Android 7.0 and above on supported devices. See our blog post for more information and how to get started

• XR: Added support for Video Async Reprojection. Video Async Reprojection allows an app to feed video frames directly into the Google VR Async Reprojection system. These frames are composited directly into the scene without going through the main Unity render loop. This provides a fast path to direct rendering of video regardless of the current frame rate Unity is rendering at. When using Async Video Reprojection, texture filtering is skipped providing for a much higher quality output. There is an option to allow for the use of protected memory for users that need to render DRM protected content.

• XR: Added support for Windows Mixed Reality as a Virtual Reality SDK target. This extends Unity's HoloLens support so that it more generally supports Windows Mixed Reality, both for desktop and HoloLens.

• XR: EditorVR is now supported without needing a custom build (still requires separate Unity Package download).

• XR: Introduced native integration for the Vuforia Augmented Reality Platform: additional feature support will follow in later beta updates. Vuforia support can be installed through the Unity Download Assistant and enabled under PlayerSettings/XR. For more information about Vuforia see https://developer.vuforia.com.

• XR: OpenVR support for Mac 64bit application target that use Metal graphics.

• XR: The single-pass instanced rendering path is now supported on desktops when the DirectX 11 rendering API is in use. Single-pass instanced rendering is only supported with forward rendering.

• XR: Windows Mixed Reality headsets are now supported for playing in-editor.

• Scripting: Editor: Load precompiled managed assemblies (.dlls) on startup even if there are compile errors in other scripts.

• Scripting: Serialization: Disabled support for opposite-endinanness asset bundles.

• Scripting: InitializeOnLoad now invoked after deserialization. See Upgrade guide for details. (879044)

• Scripting: MonoBehaviour.OnValidate is now called when adding a MonoBehaviour to a game object in the editor.

• UI: The legacy (Unity 1.0) UI system components - GUILayer, GUIText, and GUITexture - have been marked as deprecated. GUILayer components are no longer added to the camera by default.

• Universal Windows Platform: The default scripting backend on Universal Windows Platform has changed to IL2CPP.

• XR: Camera.stereoMirrorMode is now obsolete.

Improvements

• AI: Debug data from the process of building a NavMesh with the NavMeshBuilder API can be selectively collected and visualized in the Editor using NavMeshEditorHelpers.DrawBuildDebug().

2017.2.0f1 Release Notes (Full)

System Requirements Changes

• Removed iOS 6.0 support. The minimum supported version is now 7.0.

Features

• 2D: Added Tilemap.

• Asset Import: Added support for animated custom properties from FBX.

• Asset Import: Added support for Stingray material import from FBX.

• GI: Added support for per-object cast and receive shadows in the Progressive Lightmapper. For Cast Shadows, only On and Off options are supported.

• GI: Per-object lightmap seam stitching for Progressive Lightmapper.

• GI: Profiler for Realtime Global Illumination.

• GI: Support for double-sided materials in Progressive Lightmapper. Added a new material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other objects. Backface rendering is not controlled by this setting nor will backfaces be represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.

• Graphics: Implemented Display-P3 color gamut support for iOS and macOS. A "color gamut" player setting has been added, which will eventually cover other platforms with wide color gamut support.

• Multiplayer: New QoS options for delivery of large messages: reliable or unreliable, and un-ordered (fragmented) or ordered (fragmented sequenced).

• OSX: Added support for Retina in macOS standalone builds.

• Package Manager: In 2017.2, we are introducing Unity Package Manager. This will be the first stepping stone for the system. We are taking an incremental approach to integrate the system into the Unity ecosystem. It will grow with more features over time. For this first release, we avoid exposing user facing features. Instead, we are exposing an API for enabling internal components to be updated more frequently than the editor (the first pillar of the system).

• Particles: Added Linear Drag support for Particles. The new options can be found in the Limit Velocity over Lifetime Module.

• Particles: Added new option to allow Particle Systems to be destroyed or disabled when they finish playing.

• Services: Performance Reporting Service: Added support for native crashes on Android.

• Timeline: Added support for Avatar Masks on Animation Tracks.

• Video: Added pixel aspect ratio support for non-square pixel.

• WebGL: Added linear rendering to WebGL 2.0

• XR: Added support for certain aspects of the Vive HMD to be simulated in-Editor without the need of a physical HMD. Enable by using the "Mock HMD - Vive" virtual reality SDK in the player settings. The mock HMD uses the same asymmetric projection matrix, hidden occlusion mesh, field of view, aspect ratio, and eye texture size as the Vive. Mock HMD can be used with both multi and single pass rendering paths and will render as a split screen stereo display in Editor.

• XR: Added support for Google ARCore augmented reality technology when targeting Android 7.0 and above on supported devices. See our blog post for more information and how to get started https://blogs.unity3d.com/2017/08/29/ar-comes-to-android-with-the-arcore-sdk/

• XR: Added support for Video Async Reprojection. Video Async Reprojection allows an app to feed video frames directly into the Google VR Async Reprojection system. These frames are composited directly into the scene without going through the main Unity render loop. This provides a fast path to direct rendering of video regardless of the current frame rate Unity is rendering at. When using Async Video Reprojection, texture filtering is skipped providing for a much higher quality output. There is an option to allow for the use of protected memory for users that need to render DRM protected content.

• XR: Added support for Windows Mixed Reality as a Virtual Reality SDK target. This extends Unity's HoloLens support so that it more generally supports Windows Mixed Reality, both for desktop and HoloLens.

• XR: EditorVR is now supported without needing a custom build (still requires separate Unity Package download).

• XR: Introduced native integration for the Vuforia Augmented Reality Platform: additional feature support will follow in later beta updates. Vuforia support can be installed through the Unity Download Assistant and enabled under PlayerSettings/XR. For more information about Vuforia see https://developer.vuforia.com.

• XR: OpenVR support for Mac 64bit application target that use Metal graphics.

• XR: The single-pass instanced rendering path is now supported on desktops when the DirectX 11 rendering API is in use. Single-pass instanced rendering is only supported with forward rendering.

• XR: Windows Mixed Reality headsets are now supported for playing in-editor.

Revision: 5d30cf096e79

2017.1.0f3 Release Notes (Full, diff from f2 at end)

Known Issues

• Audio: On Windows, AudioSource attached to VideoPlayer produces choppy sound when game iterations are overrunning. Will be fixed in future Unity release. (895458)
• GI: Lit clustering debug visualization does not show (to be fixed in patch) (911953)
• xR: Rendering problems on Pixel Daydream when using 4x or 8x MSAA with single-pass stereo. This is due to driver issues, so the problem will be addressed via a driver update, independently of Unity releases.

Features

• 2D: Added Sprite Physics Shape to Sprite Editor, to allow users to set a custom default shape for a Sprite for generating collider shapes with a PolygonCollider2D.
• 2D: Introduced 2D Sprite Atlas, a new asset that will supplant the Sprite Packer. With it comes new and improved workflows that gives the developer more control on how to pack sprites and use them at runtime.
• 2D: Sprite Mask. Mask Sprites in world space using the new SpriteMask component.
• Animation: Manual Keyframing Workflow. Separate Recording and Preview modes in the Animation Window. Contextual menus added to all animatable properties in the inspector.
• Animation: New GameObjectRecorder in UnityEditor.Experimental.Animations
• Audio: Added support for ambisonic audio clips and ambisonic decoder plugins.
• Audio: Timeline Editor Audio Track support. Audio clips are now enabled in Timeline, using a scheduling API.
• Build Pipeline: The Asset Bundle Browser comes out of beta with Unity 2017.1. This tool enables the user to view and edit the configuration of Asset Bundles for their Unity project. It is intended to replace the current workflow of selecting assets and setting their Asset Bundle manually in the inspector.
• Collab: In-Progress. In-Progress allows developers using Unity Collaborate to see who else on their team has made local changes to a Scene or Prefab before those changes have been published.
• Editor: Added new ArcHandle class in UnityEditor.IMGUI.Controls to interactively edit arcs in the Scene View.
• Editor: Experimental feature : retained-mode UI system for the Editor (UI Elements)
• GI: Added support for baked LODs in Progressive Lightmapper
• GI: Support for double sided materials in Progressive Lightmapper. Added a new material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other objects. Backface rendering is not controlled by this setting nor will backfaces be represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.
• Graphics: Added Custom Render Texture asset. A Custom Render Texture is a new type of Render Texture that can be easily updated with a shader. It provides a user interface and a scripting framework.
• Graphics: Added LineUtility class and 'LineRenderer.Simplify' function. Optimize your lines and curves by using the LineUtility to create a simplified version with a similar shape.
• Graphics: Added partial update/readback of compute buffers
• Graphics: The latest version of the Post-processing stack is available in beta. This new version offers improved effects and a complete framework for custom effects. It also comes with a volume-based blending feature, so you can define areas in the scene and set up specific looks when the player enters them. Unity will automatically blend between volumes to allow for smooth look transitions. Final release is expected this summer.
• Graphics: Updated Splash screen logo and style
• IMGUI: Added SearchField, a new IMGUI Control. It comes with Normal and Toolbar UI styles but can also be customized.
• Input: Added new Player Settings property 'Input Manager' for enabling backend of new input system preview feature. The front-end is supplied separately and is not included with the release.
• iOS: Enable deferred shading rendering path for Metal and OpenGL ES 3.0 for A8 and later iOS devices.
• Particles: Added support for using Sprites in the Particle System, via the Texture Sheet Animation Module
• Particles: Apply Noise Module data to particles sizes and rotations, and also send the noise data to your shaders via new Custom Vertex Streams.
• Particles: New Donut emission shape.
• Playables: Playable Assets added to Playable API.
• Playables: Playable Director added to play Playable Assets
• Playables: Timeline Editor and Runtime API. A tool for sequencing animation, scripts and audio.
• Scripting: Experimental support for new scripting runtime. This includes Mono 4.8 and IL2CPP with support for C# 6 and .NET 4.6
• Shaders: Added support for "inline" sampler states.
  • HLSL SamplerState objects that aren't taking sampling state from any texture (like what "sampler"+TextureName samplers do), but where sampling state is instead derived from the name.
  • For example, "MyLinearClampSampler" sets up bilinear filtering and clamp wrap mode; while "point_repeat_sampler" sets up point filtering and repeat wrap mode.
  • This allows e.g. doing both PCF depth comparison and reading raw depth value from a shadow map in a single shader.
  • Note that generally only modern graphics APIs support separate textures & samplers. You might therefore want to specify #pragma target 3.5 or similar in your shaders for this.
  • Implemented on DX11, DX12, PS4, XB1, Metal (Vulkan not yet).
• Windows: Multi-display support for UWP.

Changes

This should also help avoiding setting the same mass for all the body parts of a ragdoll, as recommended before. See more in the API docs.
• Playables: - Changed C# Playable classes to structures: new and better approach for the API, it uses less memory and is in line with the future job system.
  • Remove properties in favor of getters and setters: since we're using class extensions that can't have properties, we decided to only use methods to have a consistent API (i.e. not properties there and methods here just because reasons).
  • Rename ScriptPlayableData to PlayableBehaviour: the PlayableBehaviour is the user side of the ScriptPlayable, it is where the user puts its logic.
  • Documentation is in progress expect a better one in a few weeks.
• Playables: Moved Playable out of Experimental namespace.
• Playables: New method PlayableGraph.IsPlaying()

2017.1.0f2 Release Notes (Full)

Features

• 2D: Added Sprite Physics Shape to Sprite Editor, to allow users to set a custom default shape for a Sprite for generating collider shapes with a PolygonCollider2D.
• 2D: Introduced 2D Sprite Atlas, a new asset that will supplant the Sprite Packer. With it comes new and improved workflows that gives the developer more control on how to pack sprites and use them at runtime.
• 2D: Sprite Mask. Mask Sprites in world space using the new SpriteMask component.
• Animation: Manual Keyframing Workflow. Separate Recording and Preview modes in the Animation Window. Contextual menus added to all animatable properties in the inspector.
• Animation: New GameObjectRecorder in UnityEditor.Experimental.Animations
• Audio: Added support for ambisonic audio clips and ambisonic decoder plugins.
• Audio: Timeline Editor Audio Track support. Audio clips are now enabled in Timeline, using a scheduling API.
• Build Pipeline: The Asset Bundle Browser comes out of beta with Unity 2017.1. This tool enables the user to view and edit the configuration of Asset Bundles for their Unity project. It is intended to replace the current workflow of selecting assets and setting their Asset Bundle manually in the inspector.
• Collab: In-Progress. In-Progress allows developers using Unity Collaborate to see who else on their team has made local changes to a Scene or Prefab before those changes have been published.
• Editor: Added new ArcHandle class in UnityEditor.IMGUI.Controls to interactively edit arcs in the Scene View.
• Editor: Experimental feature : retained-mode UI system for the Editor (UI Elements)
• GI: Added support for baked LODs in Progressive Lightmapper
• GI: Support for double sided materials in Progressive Lightmapper. Added a new material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other objects. Backface rendering is not controlled by this setting nor will backfaces be represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.
• Graphics: Added Custom Render Texture asset. A Custom Render Texture is a new type of Render Texture that can be easily updated with a shader. It provides a user interface and a scripting framework.
• Graphics: Added LineUtility class and 'LineRenderer.Simplify' function. Optimize your lines and curves by using the LineUtility to create a simplified version with a similar shape.
• Graphics: Added partial update/readback of compute buffers
• Graphics: Updated Splash screen logo and style
• IMGUI: Added SearchField, a new IMGUI Control. It comes with Normal and Toolbar UI styles but can also be customized.
• Input: Added new Player Settings property 'Input Manager' for enabling backend of new input system preview feature. The front-end is supplied separately and is not included with the release.
• iOS: Enable deferred shading rendering path for Metal and OpenGL ES 3.0 for A8 and later iOS devices.
• Particles: Added support for using Sprites in the Particle System, via the Texture Sheet Animation Module
• Particles: Apply Noise Module data to particles sizes and rotations, and also send the noise data to your shaders via new Custom Vertex Streams.
• Particles: New Donut emission shape.
• Playables: Playable Assets added to Playable API.
• Playables: Playable Director added to play Playable Assets
• Playables: Timeline Editor and Runtime API. A tool for sequencing animation, scripts and audio.
• Scripting: Experimental support for new scripting runtime. This includes Mono 4.8 and IL2CPP with support for C# 6 and .NET 4.6
• Shaders: Added support for "inline" sampler states.
  • HLSL SamplerState objects that aren't taking sampling state from any texture (like what "sampler"+TextureName samplers do), but where sampling state is instead derived from the name.
  • For example, "MyLinearClampSampler" sets up bilinear filtering and clamp wrap mode; while "point_repeat_sampler" sets up point filtering and repeat wrap mode.
  • This allows e.g. doing both PCF depth comparison and reading raw depth value from a shadow map in a single shader.
  • Note that generally only modern graphics APIs support separate textures & samplers. You might therefore want to specify #pragma target 3.5 or similar in your shaders for this.
  • Implemented on DX11, DX12, PS4, XB1, Metal (Vulkan not yet).
• Windows: Multi-display support for UWP.

Changes

• Asset Import: Upgraded FBX SDK to 2016.1.2
• Build Pipeline: Added new function SwitchActiveBuildTargetAsync. This defers switching so that scripts can be imported first.

2017.1.0f1 Release Notes (Full)

Features

• 2D: Added Sprite Physics Shape to Sprite Editor, to allow users to set a custom default shape for a Sprite for generating collider shapes with a PolygonCollider2D.
• 2D: Introduced 2D Sprite Atlas, a new asset that will supplant the Sprite Packer. With it comes new and improved workflows that gives the developer more control on how to pack sprites and use them at runtime.
• 2D: Sprite Mask. Mask Sprites in world space using the new SpriteMask component.
• Animation: Manual Keyframing Workflow. Separate Recording and Preview modes in the Animation Window. Contextual menus added to all animatable properties in the inspector.
• Animation: New GameObjectRecorder in UnityEditor.Experimental.Animations
• Audio: Added support for ambisonic audio clips and ambisonic decoder plugins.
• Audio: Timeline Editor Audio Track support. Audio clips are now enabled in Timeline, using a scheduling API.
• Collab: In-Progress. In-Progress allows developers using Unity Collaborate to see who else on their team has made local changes to a Scene or Prefab before those changes have been published.
• Editor: Added new ArcHandle class in UnityEditor.IMGUI.Controls to interactively edit arcs in the Scene View.
• Editor: Experimental feature : retained-mode UI system for the Editor (UI Elements)
• GI: Added support for baked LODs in Progressive Lightmapper
• GI: Support for double sided materials in Progressive Lightmapper. Added a new material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other objects. Backface rendering is not controlled by this setting nor will backfaces be represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.
• Graphics: Added Custom Render Texture asset. A Custom Render Texture is a new type of Render Texture that can be easily updated with a shader. It provides a user interface and a scripting framework.
• Graphics: Added LineUtility class and 'LineRenderer.Simplify' function. Optimize your lines and curves by using the LineUtility to create a simplified version with a similar shape.
• Graphics: Added partial update/readback of compute buffers
• graphics: Updated Splash screen logo and style
• IMGUI: Added SearchField, a new IMGUI Control. It comes with Normal and Toolbar UI styles but can also be customized.
• Input: Added new Player Settings property 'Input Manager' for enabling backend of new input system preview feature. The front-end is supplied separately and is not included with the release.
• iOS: Enable deferred shading rendering path for Metal and OpenGL ES 3.0 for A8 and later iOS devices.
• Particles: Added support for using Sprites in the Particle System, via the Texture Sheet Animation Module
• Particles: Apply Noise Module data to particles sizes and rotations, and also send the noise data to your shaders via new Custom Vertex Streams.
• Particles: New Donut emission shape.
• Playables: Playable Assets added to Playable API.
• Playables: Playable Director added to play Playable Assets
• Playables: Timeline Editor and Runtime API. A tool for sequencing animation, scripts and audio.
• Shaders: Added support for "inline" sampler states.
  • HLSL SamplerState objects that aren't taking sampling state from any texture (like what "sampler"+TextureName samplers do), but where sampling state is instead derived from the name.
  • For example, "MyLinearClampSampler" sets up bilinear filtering and clamp wrap mode; while "point_repeat_sampler" sets up point filtering and repeat wrap mode.
  • This allows e.g. doing both PCF depth comparison and reading raw depth value from a shadow map in a single shader.
  • Note that generally only modern graphics APIs support separate textures & samplers. You might therefore want to specify #pragma target 3.5 or similar in your shaders for this.
  • Implemented on DX11, DX12, PS4, XB1, Metal (Vulkan not yet).
• Windows: Multi-display support for UWP.

Changes

• Asset Import: Upgraded FBX SDK to 2016.1.2
• Build Pipeline: Added new function SwitchActiveBuildTargetAsync. This defers switching so that scripts can be imported first.
• Build Pipeline: Event EditorBuildSettings.activeBuildTargetChanged has been deprecated as events do not survive script reloading. Replaced with interface class IActiveBuildTargetChanged and attribute ActiveBuildTargetChanged.
• Editor: 2017 Editor now needs a new version of license. Subscription key will be upgraded. 5.x license key will not be accepted by 2017 Editor.
• Editor: Added new GameObject sub menu - 'GameObject/Effects/. This menu includes a Line andTrail creation. The particle system has also been moved to this menu.

• Editor: New projects now default to text-based serialization
• Editor: Particle trail material slot is now always visible even if it is not used.
• Editor: RenderDoc enabled for DX12 Editor mode.
• Light modes: Shadowmask and Distance shadowmask modes are now a Quality Setting and can be changed at runtime.
• OSX: Disabled Metal on macOS 10.12.2 and 10.12.3 for stability reasons if GLCore is also present in API list
• Universal Windows Platform: DX11 feature level 9.3 GPU support is required now. In practice this probably does not affect anything, as all Windows Phones that ever existed support 9.3 level already.
• Universal Windows Platform: Removed support for building Windows 8.1 and Windows Phone 8.1 applications.
• VR: Added OpenVR to the default PC VR SDK list. The default behavior is to try initializing Oculus first, followed by OpenVR if an Oculus device isn't detected.
• VR: GPU skinning can be enabled for Android VR. This is experimental, and behavior and performance should be verified on target devices.
• VR: Updated Google NDK for Android and iOS to 1.40
• Windows: "Visible In Background" player setting now defaults to on.
• Windows: Renamed "Windows Store" to "Universal Windows Platform"
