Hi everyone! You may have heard by now, AltspaceVR is updating to Unity 2019.2! This means a couple things for you world-builders:

• We are giving you an early build of AltspaceVR on this new version of Unity. The content you have uploaded in 2018.1 should technically continue to work, but in practice we have observed some changes to baked lighting and shaders, especially on Android. We highly recommend taking a moment to verify that your custom worlds and kits continue to look the way you expect. If they do not, you may need to re-export those assets in the new Unity version.
• You should start building your worlds and kits using Unity 2019.2.12f1 in addition to 2018.1.9f2. You will receive a warning from the Uploader about an unsupported version, but you can safely ignore that. We will be updating the Uploader once 2019.2 goes live to change the warning so it comes up for the old version instead of the new.
• The builds we are providing you are preview builds, and thus could have problems. Some of our official spaces, kits, or avatars may not display correctly. As such, we don’t recommend using this build for general Altspacing, but only to verify your own content. If you experience any problems with this build other than art/visual problems, please report them like normal, but make it clear in the report that it is in the preview build.
• Note for Gear/Go/Quest users: Since the preview is not coming from the Oculus Store, you will need to uninstall official Altspace and side-load the provided build. This requires an Oculus developer account and a PC. Instructions for side-loading builds can be found elsewhere online. To switch back to the live build, you will need to uninstall this build via adb, then reinstall Altspace from the store. While the preview build is installed, you will get a nag screen to update when you launch, but ignore this.

If you have a kit or template project in Unity 2018.1, follow these instructions to update and upload in Unity 2019.2:

1. Make sure you’re running Uploader v0.8.3 or later. The in-editor version number has always read “1.0.0”, so if you don’t remember updating since it came out in November, you’ll need to update it:
   1. Download the latest Uploader package from here.
   2. Open your project (in Unity 2018.1), and delete the Assets/Altspace and Assets/Plugins directories.
   3. Import the new Uploader package (Assets > Import Package > Custom Package…).
   4. Restart Unity.
2. Close Unity if you have it running.
3. Create a copy of your project folder. This will save you a lot of time if you plan on updating the 2018.1 assets during the preview, and also serves as a backup in case the upgrade fails.
4. Install Unity 2019.2.12f1:
   1. Go to the Unity Download Archive, scroll down to Unity 2019.2.12, and download it either via the Hub, or directly, as it suits you.
   2. Make sure when you install it, you also install Android Build Support, or you won’t be able to build/upload Android bundles.
5. Open your project in Unity 2019.2.12f1. It will warn you that it has to upgrade the project, but click “Confirm”.
6. Wait while Unity upgrades all your assets and meta files.
7. If you get any “blank errors” in the console after you import your project, you may be hitting a Unity bug. To fix this, close Unity, open the file C:Program FilesUnityHubEditor2019.2.12f1EditorDataToolsRoslynScriptsunity_csc.bat in a text editor, change “csc” to “csc.exe” in line 3, and save. Reopen Unity, and the error should be gone.
8. Build your asset bundles like normal for kits or templates.

Congratulations, you’ve updated your project to Unity 2019.2!

My assets uploaded correctly but I do not see them in my world

This can happen if your world data has cached your old assets. You can force-clear this by performing a space reset (via Ctrl+Shift+R in the client) or by editing any of the world’s data (such as its name or description) from the website, and then leaving/re-entering the world.

The LTS stream offers a stable version of Unity for those who want to lock in their productions on a specific version of Unity for maximum stability.

The latest long-term support release of Unity

With the LTS and the TECH stream releases to choose from, you can pick the release that best fits your needs, depending on where you are in your development cycle. For creators who are about to embark on projects that are past the prototyping phase, Unity 2019.4 LTS provides stable, high-quality features that are supported for two years. You can confidently create your projects with that version during development and release.

Unity 2019 LTS stream has the same feature set as the 2019.3 TECH stream release.

Explore Unity 2019 features

Since the release of 2018 LTS, we’ve added hundreds of improvements and new features. Unity 2019 LTS makes artists and designers more productive with better tools and a new Editor UI. Our Scriptable Render Pipeline (SRP) technology, now out of Preview, helps you achieve best-in-class graphics on all platforms. We’ve also optimized Unity under the hood to facilitate more immersive experiences at runtime and to accelerate your project iterations.

Graphics

If you need scalability for all supported platforms, high performance, and best-in-class visual quality, the Universal Render Pipeline is our recommended production-ready solution. To help you achieve stunning high-fidelity graphics on high-end hardware (PC, consoles, and future hardware), the High Definition Render Pipeline (HDRP) is now out of Preview, which means those of you already working with it will have a consistent upgrade path.

Scripting

Our default code editor is now Visual Studio 2019, and IDE support has moved to packages. This LTS release also brings huge improvements to profiling, such as Player Deep Profiling and Call Stacks support. In Unity 2019 LTS, the Burst Compiler optimizes your output for the platform you’re compiling for, which can lead to huge performance improvements. Burst Compiler 1.3 offers native debugging and improved scalability and usability. .NET 4.x is now the default scripting runtime. Incremental Garbage Collection minimizes garbage collection spikes. Also, several quality-of-life improvements to scripting workflows reduce iteration times and make you more productive.

Artist and designer tools

Shader Graph is now our production-ready solution for building shaders visually. Visual Effect Graph empowers you to create beautiful VFX in real-time, without coding, and is now compatible with Shader Graph. Unity 2019 also helps artists achieve more, directly within the Unity Editor, with new and improved terrain tools, as well as ProBuilder, our unique hybrid of 3D modeling and level design tools.

Editor updates

We’ve given the Editor UI a new look and feel by updating icons, fonts, and user feedback systems. Unity 2019 LTS increases clarity in the Editor, so creators can focus more on their content. Since Unity 2018 LTS, we’ve also added loads of workflow improvements to make you more productive in the Editor, such as Prefab Asset Editing in Inspector, Quick Search, Presets and Shortcut Manager. Unity 2019 LTS uses Asset Import Pipeline V2 to provide you with asset-dependency tracking and many other improvements, laying the foundation of a more reliable, performant and scalable pipeline and speeding up your import times significantly.

Platforms

For mobile developers who aim to push mobile graphics and performance, Unity 2019 LTS brings improvements such as on-demand rendering, Adaptive Performance and improved OpenGL support.

Throughout 2019, we’ve also added and polished lots of tools for augmented reality (AR) and virtual reality (VR) developers. AR Foundation, our framework for multiplatform AR development, gives you the power to build your app once and deploy across ARKit, ARCore, Magic Leap and HoloLens platforms. With the High Definition Render Pipeline for VR, you can push your VR experiences to the next level of fidelity without sacrificing performance.

We now also offer support for approved developers to create and ship their games on Google’s Stadia cloud gaming platform.

2D Tools

Unity now has the 2D feature sets and workflows you need for bone-based 2D animation, tile-based and organic world-building, and 2D physics, for projects of any scale on any platform.

Addressables

Efficiently manage complex live content. The new Addressable Asset System gives you an easy way to load assets by “address,” while also handling asset management overhead by simplifying content pack creation and deployment.

Visual Effect Graph with Shader Graph integration

Visual Effect Graph now lets you use Shader Graph to create high-fidelity visual effects, so you can visually author your own pixel and fragment shaders and use them in VFX Graph to create custom looks.

Timeline Signals

Timeline Signals offers an easy way for Timeline to interact with objects in a scene. Timeline Signals lets relevant systems know that it’s time to react to a specific event, for example, when a cutscene created with Timeline ends and you want to load a new scene and enable a physics system.

UI Toolkit

UI Toolkit(formerly UIElements), a retained-mode API, helps you create Editor tools. You build your UI hierarchy of objects while the system renders it optimally, for better overall performance. By decoupling hierarchy and styling from functionality, UI authoring is more approachable for both programmers and artists with UI Builder.

Unity as a Library

Unity as a Library lets you insert features powered by Unity directly into your native mobile applications, including 3D or 2D real-time rendering functions, such as augmented reality, 2D mini-games or 3D models, and more.

AR Foundation

AR Foundation combines the full power of the Unity platform with essential core features from ARKit, ARCore, Magic Leap, and HoloLens for rich immersive AR applications that you can build once and deploy across platforms.

Incremental Garbage Collector

With incremental garbage collection, rather than processing garbage collection all at once, we split the operation over a number of frames. This helps reduce occasional spikes in CPU usage due to garbage collection.

We prepared a series of upgrade guides to help you go from Unity 2017 LTS or Unity 2018 LTS to Unity 2019 LTS. For complex productions with a high number of dependencies, find out how our Success Plans can ensure the upgrade process goes smoothly.

What to expect from Unity LTS

Making the current LTS stream the most stable version of Unity is our top priority. Biweekly updates are intended to address crashes, regressions, issues that affect the wider community or console SDK/XDKs, and any major issues that would prevent a large number of developers from shipping their projects.

Unity release plans

We’re committed to supporting 2019.4 LTS releases with biweekly fixes until mid-2021, and then monthly updates until mid-2022.

Unity 2018.4 is now the legacy LTS and will be updated once every month until it reaches the end of its support cycle in spring 2021.

Archive

Looking for a specific Unity LTS release? We’ve organized all LTS releases in one simple archive page. Or subscribe to our RSS feed and get access to the latest LTS as soon as it’s released.

The last TECH stream release of the year becomes a Long-Term Support (LTS) release and receives continued support for another two years in the form of biweekly updates with bug fixes. In terms of versioning, we increment the final TECH stream release of the year by one and add “LTS” (for example, TECH stream release 2018.3 became 2018.4 LTS).

The LTS releases do not include any new features or breaking API changes compared to the TECH stream releases that they are based on. Their updates address crashes, regressions, issues that affect the wider community or console SDK/XDKs, and any major issues that would prevent a large number of developers from shipping their games or apps.

The LTS stream is for developers who want to develop and ship their projects on the most-stable version and remain on this version for an extended period.

TECH stream releases are for developers who want to access the latest features and capabilities. The 2019 TECH stream had three releases (2019.1, 2019.2, and 2019.3). We add updates and bug fixes to the current TECH stream release on a weekly basis until the next TECH release is officially launched; then the cycle begins again.

Unity 2019.4, which we also refer to as Unity 2019 LTS, doesn’t have any new features, compared to Unity 2019.3. Updates to Unity 2019.4 include only fixes for crashes, regressions, issues that affect the wider community or console SDK/XDKs, and any major issues that would prevent a large number of developers from shipping their games or apps.

If you are in production or close to release, we recommend the latest LTS release. If you want to use the latest Unity features in your project or are just getting started with production, the TECH stream is recommended.

Unity 2019.3 Download

The 2019.4 LTS releases will receive biweekly fixes until mid-2021, and then monthly updates until mid-2022.

Yes. Generally, our process is to fix bugs in the next release of Unity, and then backport the fixes to current TECH streams and LTS branches. The exact mechanics for doing that depend on the nature of the bug, the dependencies it may have to other components, and other factors. We have a team fully engaged to backport fixes to Unity 2019 LTS.

Unity 2019.3.1f1

Alphas are the first public releases of a new TECH stream version of Unity. During the alpha phase, we’re progressively adding all the new features that are scheduled to be part of the final release. At the same time, the features get tested collectively for the first time. While a TECH stream version is in alpha, we release updates with new features on a weekly basis until we reach feature completeness. As such, alphas come with a higher stability risk than beta releases, which are feature-complete and receive only stabilizing updates. With both alphas and betas, you have an opportunity to influence our development process by using the new features and providing feedback via forums and bug reports.

Because there may be feature-stability issues with these early releases, we do not recommend them for projects in production; we highly recommend that you back up any project before you open it with an alpha or beta release.

Unity 2019.4.9f1

Both our alpha and beta releases are open to everyone – no signup is required. Get started by downloading them from the Unity Hub.
