This plugin allows developers to create web-based user interfaces with HTML, JavaScript, and CSS. These widgets also support passthrough transparency for mouse and touch events in 2D along with virtual pointer events in 3D. It’s powered by a custom Chromium web browser on desktop, with ultra fast 4K 60FPS using accelerated paint, and the built-in WebView browsers on mobile. This plugin also includes a robust JSON library that provides integrated management of objects, arrays, and primitive data types to seamlessly interop between JavaScript and blueprints.
