This package only supports Windows and macOS. To support other platforms, you can install additional 3D WebView packages (Android, iOS, UWP, WebGL, or create a custom bundle). All of the 3D WebView packages work seamlessly together, so all you need to do is install them into the same project, and then 3D WebView automatically detects and uses the correct plugin at runtime and build time.
3D WebView's native Windows and macOS plugins are provided as precompiled libraries, and the native source code for them is not provided.
The H.264 video codec for MP4 and streaming is disabled by default but can be enabled.
The Windows plugin supports building for x86, but the resulting 32-bit app will only run on 64-bit versions of Windows because 3D WebView embeds a 64-bit Chromium executable.
Building for the Mac App Store is not supported.
On macOS, the dynamic library used by the Unity process is a universal library that supports both x64 and arm64. The executable for the Chromium process is currently x64 only but runs successfully on M1 Macs via Rosetta.
The Windows and macOS plugins embed Chromium Embedded Framework, so you must display a copy of its included BSD-style license in your desktop app's about page or credits.
