APK file size validation for Android App Bundles

Mobile

When you chose to release to Google Play store with Android App Bundle AAB (more info https://blogs.unity3d.com/2018/10/03/support-for-android-app-bundle-aab-in-unity-2018-3-beta/), we check the size of AAB at the end of the build process. If it’s greater than 500Mb we display a warning, and give you the option to compute the sizes of the individual APKs.

Asset Pipeline V2

Asset Management

Introducing the new and improved asset import pipeline V2 as the default choice for new projects.

  • Introduces dependency tracking, faster hashing, fast platform switching and a number of new options to greatly improve working with large projects over its V1 predecessor.
  • Complemented by a new V2 Cache Server, greatly improving import times for V2-enabled projects when working with multiple team members.
  • Asset pipeline V1 projects have the option to upgrade to use V2.

Fast Enter Playmode without DomainReload

Scripting

Lets users enter Playmode without reloading assemblies, reducing iteration time. This feature can be enabled from within Project Settings.

HDR support for UWP and Windows

Editor

Brings HDR support on UWP and Windows standalone into feature parity with the support already in place for consoles, using graphics APIs DX11 and DX12.

DirectX supports two combinations of swap chain pixel formats and colorspaces for HDR content:

  • Option 1: FP16 + DXGI_COLOR_SPACE_RGB_FULL_G10_NONE_P709
  • Option 2: R10G10B10A2 + DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020

You will be able to select the colorspace by simply changing the display bit depth to either 10bits or 16bits (10Bits is RGB B.709 and 16 bits is RGB B.2020).

HDRP Verified Package

Graphics
Package
SRP
  • HDRP package (which includes HDRP post-processing) out of preview
  • LookDev feature added giving you better previews in editor
  • Experimental feature: Physically-Based Sky

Incremental GC out of Experimental

Base Libraries

The Incremental Garbage Collector is able to split its work into multiple slices. Instead of having a single long interruption of your program’s execution to allow the GC to do its work, you can have multiple, much shorter interruptions. While this will not make the GC faster overall, it can significantly reduce the problem of GC spikes breaking the smoothness of animations in your project by distributing the workload over multiple frames.

Keyframing Improvements for Animation Rigging

Animation

Enable previewing of effector keyframing in Timeline “Animation” track. You can now manipulate your animation rig from the Animation Window and Timeline.

Unity Blog (provides context but does not specifically explain this improvement): https://blogs.unity3d.com/2019/09/05/advanced-animation-rigging-character-and-props-interaction/

Mobile Notifications Verified Package

Mobile
Package

The Mobile Notifications package helps you implement retention mechanics and timer-based gameplay by adding support for scheduling local repeatable or one-time notifications on iOS (from iOS 10) and Android (4.1 and above).

Native Graphics Jobs out of Experimental

Graphics

The graphics jobs feature is out of experimental status for the standalone player on desktops and console platforms, bringing performance improvements on projects that enable it.

  • Graphics jobs are now enabled by default for all new 3D projects on desktops or console platforms.
  • This feature is still experimental for the Metal graphics API and Vulkan on Android platforms.
  • This feature is only supported for the standalone player, and not supported in the Unity editor.

On-Demand Rendering

Mobile

This feature lets you control the rendering loop independently from the rest of our subsystems. This means you have more control to lower power consumption and prevent thermal CPU throttling.

Progressive Lightmapper Improvements

Graphics
Lighting
  • Adjustable Light Probe quality for baking: We’ve added the ability to adjust the sampling count (aka quality) for Light Probes separately from lightmaps. This will be especially noticeable in scenes with tucked away emissives and other difficult lighting scenarios. The sample count is now adjustable in the lighting panel – no longer a fixed number.
  • AMD Radeon ProRender AI Denoiser: we've added support for this AI-based denoiser. This means that with fewer samples you can get the same great results and faster speeds!
  • Support for box and pyramid spot light shapes for HDRP.

Refreshed Editor Theme

Editor

Refresh of the existing UI theme to improve clarity and provide a content-first experience for users by eliminating clutter, unnecessary elements such as gradients and drop shadows.

  • Features new icons with uniform style to convey concepts more clearly, with full High DPI support.
  • Comes with a new UI font, Inter, which is more legible and scales well across many different types of UI and display types.
  • Adds hover state to controls, which brings the UI alive and makes it feel more responsive.

Serialization of managed references

Scripting

There are several cases where Unity objects fail to serialize and deserialize correctly. The problem takes many forms, from failed polymorphism, to errant object or null references, to inability to store trees and graphs. New fixes in the YAML file structure address these problems.

Terrain Holes

Terrain

Now in Unity terrain you can create holes, letting you better create and blend custom meshes into the environment.

UNET encryption support

Networking

This feature provides you with a way to manipulate the UNET network payload in order to add encryption and extra layers of security as required by your projects.

  • Allows you to secure all UNET communication between your clients and servers, which is a requirement on some Console platforms when using cloud-based dedicated servers.
  • Can also be of use on online games for security purposes.

Unity as a library for native mobile apps

Mobile

You can now insert features powered by Unity directly into your native mobile applications. These features include, but aren’t limited to, 3D or 2D real-time rendering functions such as augmented reality, 2D mini-games or 3D models.

You can integrate the Unity runtime components and your content in a native platform project. The Unity Runtime Library exposes controls to manage when and how to load/activate/unload within the native application.

Unity Support for Stadia

Desktop

Production-ready support for Google’s new Stadia platform, inclusive of the latest and upcoming Unity features like DOTS and HDRP, plus exciting features unique to Stadia like Stream Connect, State Share & more.

Video Hardware Acceleration on Windows/UWP

Video

Video decoding – e.g., H.264, H.265, as found in MP4 files – for Windows/UWP means enabling DXVA (DirectX Video Acceleration) with Microsoft’s Media Foundation. For Windows 8 and above, we’ve reworked Unity’s usage of this API to decode video into textures rather than into memory on systems where hardware acceleration is available.

The pre-existing approach always uses software decoding to memory, which provides wide compatibility, but this does not utilize available video decoding hardware resources. The new approach enables GPU-assisted video decoding directly into textures, thus saving CPU, memory usage, and bandwidth.

Addressable Assets System for Creating, Managing and Loading Content

Asset Bundles
Asset Management
Build
Package

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.
