Unity Roadmap

Enable ARM64 bit support for Android, based on IL2CPP technology. Running 64-bit Android apps will have performance benefits, plus games will be able to address more than 4 GB of memory space.

Certificate validation using .Net or UnityWebRequest APIs now validates against the platform system CA store where possible.
On XboxOne, PS Vita and Nintendo 3DS, which doesn't provide access to system store validation, an embedded CA store is used for validation.

Support for TLS 1.2 (secure socket) from .NET code

As our [blog](https://blogs.unity3d.com/2017/08/11/unityscripts-long-ride-off-into-the-sunset/) noted, we are dropping UnityScript support.

• Stopped accepting new Asset Store packages with UnityScript code
• Notified Asset Store author and removed Asset Store Package with UnityScripts
• Implemented [conversion tool](https://github.com/Unity-Technologies/unityscript2csharp)

Support for per-monitor display scale factors on Windows.

IL2CPP managed debugging enables developers to use their preferred debugger to find and fix errors, even when using the IL2CPP back end. All debugging features should be supported for Visual Studio (with Visual Studio Tools for Unity) and Jetbrains Rider on Standalone, Playstation 4, and Mobile platforms.

Updates Camera component to optionally allow setting Focal Length / Sensor Size instead of vertical FOV in "Physical Camera" mode. These values will also be imported from FBX.

TLS 1.2 is now supported across all platforms. This brings the ability to secure your network traffic with the latest standards.

Ability to add .java (and .cpp) source files to Unity project plugin folder and those will be recognized as Unity plugins without requiring to separately build libraries for plugins in Android studio.

Support for up to 8 UVs for model import, Mesh API and in shaders. Previously the maximum was 4.

The Texture mipmap Streaming system gives you direct control over which mipmap levels are loaded into memory. Helping reduce the total amount of memory required for textures by only loading the mipmaps needed to render the current camera position in a scene. It trades a small cost of CPU for GPU memory saving.

Adds a number of small improvements to the TrailRenderer:

• SetPositions/AddPositions API
• Trails smoothly remove their old points, to remove visual popping.
• A new "Emit" checkbox, to allow trails to start/stop emitting geometry.

Experimental support for running the editor on Vulkan for both Windows and Linux.

Implement multi-threading support in WebAssembly using the upcoming Shared Array Buffers feature in Javascript.

Methods for obtaining polygonal geometry, compatible with the C# job system

Faster APK package build times on Android with internal build system: allow using apkzlib instead of aapt / apkbuilder when building Android applications.

Methods for doing raycasts on the NavMesh, compatible with the C# job system.

Update to use the Roslyn compiler. This will let users use the latest C# 7 features.

Support for GPU acceleration of the Progressive Lightmapper. Light baking with the Progressive Lightmapper will be significantly faster. This will improve iteration and baking times. Does not affect the Enlighten baking backend.

Enables tilemap users to build isometric or hexagonal tilemaps.

Sometimes probes cannot faithfully represent the actual lighting information in a scene. In such cases “ringing” may occur which manifests itself as unwanted rings in objects lit by light probes. When enabled, the new feature removes ringing at the cost of reduced accuracy and contrast.

This update introduces a number of improvements to Unity’s Prefab workflows.

1. Nested Prefabs. Yes, it’s finally happening.
2. Prefab Variants. This feature lets a Prefab inherit the properties of another Prefab.
3. Prefab Mode. New workflow for editing Prefab assets in isolation. You’ll no longer need to drag a Prefab to an open Scene to edit it.

• Burst Probability: Adds a new property to the Burst UI, which gives bursts a random chance of not being triggered at all.
• External Forces Upgrade: Introduces a new ParticleSystemForceField Component, which can be assigned to the External Forces Module of Particle Systems. This new Component offers a variety of controls, for gravity, drag, vortex motion, etc, when particles are inside its volume.
• Flip Option: We have moved the FlipU/FlipV options from the Texture Sheet Animation Module into the Renderer Module and enabled flipping on each axis for Mesh Particles. Be sure to use a shader with backface culling disabled, when flipping your meshes!
• Ordered Mesh Emission: A new option in the Shape Module for meshes, called "Vertex Ordered", which emits particles from each vertex of the mesh in order. This option behaves similarly to the Systematic option in the Legacy Particle System and is being added prior to the final removal of the Legacy Particle System.
• Ring Buffer Mode: A new Particle System mode where particles don't die when their lifetimes elapse. Instead, they remain until the Max Particles property is exceeded, at which point the oldest particles are replaced when new ones spawn. Useful for footprints, bullet holes, etc, and other persistent objects, where the user wants them to stay as long as possible, whilst maintaining a maximum budget.
• Roll Option (for VR): A new checkbox to disable roll when the camera rolls. This is most useful in VR applications where users do not want particles to follow the camera when the user rolls their head from side to side.
• Shape Module Improvements:
  • Add visualization of the Radius Thickness property in the Scene View.
  • Allow the Arc property to be used on the Sphere/Hemisphere shape.
• Texture Sheet Animation Improvements: Adds 2 new modes to the Texture Sheet Animation Module:
  • An FPS mode, where animations play at a fixed FPS, regardless of particle lifetimes.
  • A speed-based mode, where the animation frame is chosen based on particle speed, rather than age.

Upgrade NVIDIA PhysX from 3.3 to 3.4

It is time to remove the Legacy Particle System.

We are providing an upgrader on GitHub, which will convert Legacy Components (e.g. ParticleEmitter) into new Components (e.g. ParticleSystem). this upgrade should be performed in Unity 2018.2 or earlier.

Starting with Unity 2018.3, Legacy Particle Components will not work.

In 2018.3 SpeedTree v8 assets (*.st files) are recognized and imported using SpeedTree importer:
• A new SpeedTree8 shader is used by the generated materials.
• Supports per-LOD approximated sub-surface scattering effect.
• Supports top-down billboards.
• Supports back face lighting.
• Improved vertex shader performance.

Addressable Assets handle the code complexity of creating, managing, and loading content by removing the steepest part of the learning curve and automating tedious tasks. Addressable Assets decouple the project code and content layout to eliminate the need for tracking assets and refactoring code. By starting with Addressable Assets, your game development can scale without increasing complexity. The game creator no longer needs to think about shipping details while making their game.
