Unity 2017.1.0 Beta 2

2017.1.0b2 Release Notes (Delta since b1)

Known Issues

• Android: Android Build fails when the latest Android SDK Tools 25.3.1 version is used (888859)
• Animation: Imported animation for humanoids is incorrect (904985)
• Audio: AudioSource attached to VideoPlayer produces choppy sound when playing certain mp4 files with VideoPlayer created from script (895458)
• Editor: "The system cannot find file specified" error while opening the project for the first time. Deleting Library folder resolves the issue. (895343)
• Editor: Editor crashes on attempt to open some 5.5 compatible audio projects. (880653)
• Editor: Text in Editor becomes red after dismissing EditorUtility.DisplayDialog() popups. (886650)
• Editor: Unity crashes when playing a scene with maximized game view (894572)
• Graphics: Debug GFX overlay is drawn on top of objects. (851379)
• VR: 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. (-)
• Windows: Edit menu has duplicate menu items (Undo, Cut, Copy, Paste, etc) (905191)

Features

• Asset Import: Added ability to import visibility from FBX files to ModelImporter
• Audio: Timeline Editor Audio Track support. Audio clips are now enabled in Timeline, using a scheduling API.
• 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: Mesh particles now support the same Render Alignment options are billboarded particles
• Particles: New Donut emission shape.
• Particles: Play Particle Systems when your game is paused, by choosing to use either Scaled or Unscaled time for the simulation.
• Particles: The Shape Module now contains an additional Transform, for applying custom transformations to the emitter shape.
• Physics: Add ability to manully simulate 2D physics using "Physics2D.Simulate(time)" and turn auto simulation on/off with "Physics2D.autoSimulation=true/false".
• Physics: Expose Physics.Simulate and Physics.autoSimulation. This allows stepping the physics simulation manually, from scripts. Useful for customising the server-side physics, in-editor simulation, and more.

It's mostly useful for ragdolls that have high forces applied to their limbs and thus experiencing unpleasant stretchiness. 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.

• Audio: Timeline Editor Audio Track support. Audio clips are now enabled in Timeline, using a scheduling API.
• Build Pipeline: Added delegates to BuildPlayerWindow that allow overriding the default Build button behavior
• 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 (UIElements)
• GI: Added new API for setting Light falloff per Light. Added API for setting all Lights to use physically correct inverse squared falloff or the Unity legacy falloff model. Only used for Enlighten lightmaps so far, realtime and progressive will be supported later.
• Graphics: Added LineUtility class and 'LineRenderer.Simply' function. Optimize your lines and curves by using the LineUtility to create a simplified version with a similar shape.
• Graphics: Added memoryless mode to RenderTexture, accessed through new property RenderTexture.memorylessMode.

• 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: Particles can now apply forces to the Colliders they hit
• Particles: Play Particle Systems when your game is paused, by choosing to use either Scaled or Unscaled time for the simulation.
• Particles: The Shape Module now contains an additional Transform, for applying custom transformations to the emitter shape.
• Physics: Add ability to manully simulate 2D physics using "Physics2D.Simulate(time)" and turn auto simulation on/off with "Physics2D.autoSimulation=true/false".
• Physics: Added 'Joint2D.attachedRigidbody' property to retrieve the Rigidbody2D attached to the Joint2D.
• Physics: Expose Physics.Simulate and Physics.autoSimulation. This allows stepping the physics simulation manually, from scripts. Useful for customising the server-side physics, in-editor simulation, and more.
• Physics: Exposed Joint.massScale & Joint.connectedMassScale. This allows adjusting masses and inertia tensors of the connected bodies as perceived by the solver. It's mostly useful for ragdolls that have high forces applied to their limbs and thus experiencing unpleasant stretchiness. 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.
• Physics: When setting 'Rigidbody2D.simulated' to false, Editor inspector shows information about its effect.
• 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).
• Web: A new UnityWebRequest.timeout property that gives the user some coarse-grain control over the time a webrequest can take before unity attempts to cancel it.
• Windows: Multi-display support for UWP.

• Build Pipeline: Added new function SwitchActiveBuildTargetAsync. This defers switching so that scripts can be imported first.
