You can find out more about C# 8 features here.
Consistency check for asset importers
Consistency check functionality to verify that asset importers produce deterministic results from a given input and set of dependencies.
The consistency check can be activated either by manually reimporting an asset or via the “-consistencyCheck” or “-consistencyCheckSourceMode” command line arguments.
Hierarchy View Improvements
- Can set a game object as “default parent” in the hierarchy; newly created or dragged into the scene objects will get parented under that.
- “Create Empty Parent” context menu item on game objects; wraps selection into a new empty parent object.
- Newly created objects go into “rename” mode by default. This can be turned off via hierarchy window settings menu.
- Version control integration (Perforce) can display VCS status overlays for prefabs in hierarchy.
- More intuitive shift-click behaviour to select items (extends selection from previous click, not from first click).
Import pipeline for 2DArray & 3D textures
“Flipbook” layout images (a grid of columns/rows with individual images) can now be imported as 2DArray or 3D textures.
Improve IL2CPP Iteration Time
- 0-Change rebuilds in IL2CPP platforms: IL2CPP conversion from .NET assemblies to C++ is skipped when making changes to assets that don’t involve code changes, for example to materials, shaders or prefabs. This improves artist workflows and speeds up iteration.
- IL2CPP player build time improvement: the process of converting .NET assemblies into C++ files has historically been single-threaded. In Unity 2020.2, the application that processes the conversion (il2cpp.exe) takes advantage of modern multi-core processors, dramatically decreasing the overall IL2CPP player build times.
- Array and List variables use reorderable list UI control by default. Can use [NonReorderable] attribute on C# variables to fallback to the old non-reorderable control.
- Mesh inspector can visualize blend shapes when they are present, and can also pan/zoom into the viewed mesh.

Progressive Lightmapper Improvements
- Increasing the bounce limit for both GPU and CPU Lightmappers.
- Adding Blue Noise Sampling to improve the quality of lightmaps.
- Reducing memory usage in the GPU Lightmapper. When baking large lightmaps progressive updates will be disabled when memory runs low. Additionally, the Lightmapper will automatically throttle memory usage internally. This enables the GPU Lightmapper to bake larger projects.
Project View Improvements
Making asset rename & move operations undoable.
Unity Recorder is now a fully Released package as of version 2.5.
Use the Unity Recorder package to capture and save data during play mode. For example, you can capture gameplay or a cinematic and save it as an mp4 file.
You can set up the following types of Recorder:
- Animation Clip Recorder: generates an animation clip in .anim format.
- Movie Recorder: generates a video in .mp4 or .webm format.
- Image Sequence Recorder: generates a sequence of image files in .jpeg, .png, or .exr (OpenEXR) format.
- GIF Animation Recorder: generates an animated .gif file.
- Audio Recorder: generates an audio clip in .wav format.
Safe Mode is a feature to guide you through the process of fixing script compilation errors that can come about from upgrading a project created in an earlier version of Unity.
In Safe Mode, non-script assets don't get imported until all script compilation errors have been fixed. This avoids the potential double-importing of assets that could trigger from invalidation of scripts after fixing compilation errors. Additionally, only a limited Unity assembly domain is loaded when Safe Mode is active: assemblies and package assemblies are not loaded. This allows you to concentrate on resolving script compilation issues first, before Unity exposes other issues that may need addressing, but that are not useful to report until script compilation is clean.
During Safe Mode, the UI is limited to providing the functionality that is relevant for fixing the script compilation errors. Game Hierarchy, Scene View, etc. are not available, for instance.
Scene View Improvements
- Thicker Move/Rotate/Scale tool handles by default (thickness can be set in preferences). Additionally, improving their picking logic, particularly for cases when it was not intuitive before.
- Multiple selected prefabs can be dragged into the scene view from the project view. Previously such operation was placing just one of the dragged prefabs.
- “Shaded Wireframe” scene view mode now works with HDRP/URP.
- Optimizing Gizmos rendering for large selections; up to 4x faster in some cases now.
- Keyboard shortcut for scene camera placement copy/paste. By default, there’s no key assigned, but you can assign it in the shortcut manager.
- Frame Selected (“F” shortcut) on an already framed object now zooms into its pivot point.
- More intuitive ctrl/cmd-click behaviour to deselect already selected prefabs.

- Per-particle Mesh LOD: optimize your effects by setting LOD meshes based on the screen size in the mesh output.
- Multi-Mesh: use up to 4 meshes with the same mesh output to add per-particle variety to your effects.
- Culling optimizations: culling is done with compute shaders to discard the rendering of inactive or off-screen particles efficiently.
Support reference assemblies in the compilation pipeline
Unity will use Roslyn Reference Assemblies to skip compilation of references (to a modified asmdef assembly) by default if the public assembly metadata does not change. For example, if you modify only private methods or fields, only the modified assembly will be recompiled.
Version Control Improvements
- Perforce integration better understands “exclusive checkout” file status now.
- Asynchronous status queries VCS setting is on by default now.

Lighting Settings and Improvements
Several improvements including:
- Lighting Settings Asset, which allows you to reuse settings across your scenes
- Overlap-Free Packing, Calculated Pack Margins and a new Scene View mode for verifying your setup makes it easier to get a great lighting result, avoiding UV overlapping artifacts.
Major Shader System Improvements
Removal of synchronous compilation from the shader import phase and added on-demand/background compilation of compute shaders: compute shader compilation no longer happens during the import process. This makes compute shader importing fast and gets rid of blocking Editor behavior. All the required variants are still compiled in time for use both in the Editor and in player builds.
- Partial presets (applying only a partial set of properties from a given Preset)
- Preset drag & drop over imported files in project browser
- Glob searching on path names (filtering in the Preset Manager based on a file’s path)

- 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.
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
- 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
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
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.
Now in Unity terrain you can create holes, letting you better create and blend custom meshes into the environment.
UNET encryption support
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 (Baselib) for native mobile apps
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.

Video Hardware Acceleration on Windows/UWP
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.

Particle System Improvements 2018.3
- 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.
PhysX 3.4 Upgrade

GPU Instancing Improvements
- Per-instance properties are now packed into a structure data type. One instancing constant buffer contains only one array of such structures.
- For most platforms the instancing array sizes no longer need to be specified by user: they are instead calculated automatically (maximum allowed constant buffer size / size of the above mentioned structure type).
- Instancing batch sizes are therefore improved on OpenGL and Metal, and instancing shader variants compile much faster and potentially costs less in terms of CPU-GPU data bandwidth.

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.
Enable 16 bit floating point format for emission for both realtime and baked GI.
HDR color picker limit increased from 99 to 64k.
