FAQs

Is Unity WebGL deprecated? ›

In Unity 2022.1, the WebGL 1 graphics API is no longer included in the Auto Graphics API setting. If you need to add support for WebGL 1 to your project, open the Player Settings and under Player → Other Settings, uncheck the Auto Graphics API option and explicitly add “WebGL 1 (Deprecated)” to the Graphics API list.

It supports browsers providing the following conditions are true: The browser is WebGL 2 capable. Note: Unity no longer provides support for WebGL 1 in builds created with the Auto Graphics API option. For more details, see WebGL 1 deprecation.

That 2GB limit is imposed by the browser for each tab, and this includes memory for everything on that tab - cache, images, html, javascript, the unity app and so on.

Compression Format

Brotli compression offers the best compression ratios. Brotli compressed files are smaller than gzip, but take a longer time to compress, which increases your iteration times on release builds. Chrome and Firefox only natively support Brotli compression over HTTPS.

WebGL uses GLSL (OpenGL Shading Language) whereas WebGPU uses WGSL (WebGPU Shading Language), though you can argue that these map to each other somewhat directly. Debuggability - WebGPU has richer error handling and better error messages.

WebGPU is a JavaScript API provided by a web browser that enables webpage scripts to efficiently utilize a device's graphics processing unit (GPU). This is achieved with the underlying Vulkan, Metal, or Direct3D 12 system APIs. On relevant devices, WebGPU is intended to supersede the older WebGL standard.

Unity web player has been discontinued for quite a long time now. There is absolutely no reason to waste your time developing for an obsolete platform.

unity is introducing slowly more and more webgpu support, but again you are at the mercy of browsers and the like…

Technical overview. To run in WebGL, all code needs to be JavaScript. We use the emscripten compiler toolchain to cross-compile the Unity runtime code (written in C and C++) into asm. js JavaScript.

WebGL is supported on Chrome. Opening local files is not supported in the webplayer due to security reasons; I expect the same for WebGL. Chrome does not support WebGL content from file:// urls - Use Build & Run, or upload it to a server - or use Firefox.

How do I speed up my Unity WebGL build? ›

Enable Data caching so that Unity caches your contents asset data on the user's machine. Data caching can make the application run faster.

The only thing that matters is the texture import settings in Unity. You should use whatever is most convenient (which is usually PSD since you can keep the layers and so on). Also avoid lossy formats such as JPG since they lose information.

Unity has the ability to use DirectX 11 and OpenGL Core graphics APIs, with all the features that you expect from them: compute shaders, tessellation shaders, shader model 5.0 and so on.

The best way to view the WebGL Player locally is to use Unity's Build And Run option (menu: File > Build And Run). Unity uses a local web server to host your build, and opens it from a localhost URL. Alternatively, you can use a custom local web server with properly configured response headers.

It depends on browsers actively stripping OpenGL support from their builds. As long as a fraction of the web still uses WebGL functionality it will be around as an API, just used less. Chrome and Safari both implement WebGL using the ANGLE library on all platforms. Firefox has its own WebGL implementation library.

please check if hardware acceleration is enabled.

If restarting did not help, check if your graphics card is one of the blacklists that exist for different configurations. If you recognize your graphics card on this list, it means you are out of luck with using WebGL.

Unity 2020.3 reached end of life in mid 2023. It is now approaching mid 2024. since 2020. x has been out of LTS for so long now we have removed those versions according to the published deprecation schedule, and since nobody asked for an exception to be made we continued with the plan as published.
