Version 0.20.0 also dropped the support for Built-in Render Pipeline, which needs more investigation if it’s possible to add back.
⚙️ WebXR APIs support
WebXR Device API - Supports Unity Display and Input XR Subsystems
WebXR Gamepads Module (Including hapticActuators on supported devices) - Supports Unity New Input System
WebXR Augmented Reality Module
WebXR Hit Test Module (Currently limited to viewer space Hit Test source) - Not using AR Foundation hit test
WebXR Hand Input - Supports Unity XR Hands package
WebXR Input Profiles using WebXR Input Profiles Loader - Supports XR Interaction Toolkit
More features
Spectator Camera
📊 Polyfilled WebXR / WebVR
If the user does not have supported headset, browser or device, the content will still work through the use of the WebXR Polyfill.
📱 Mobile support
This asset works by utilizing Unity’s WebGL platform support and therefore shares the same limitations. Because of this, mobile support is limited and may not work. We did made sure to make it light, so mobile devices would be able to handle it, and it is able to run on high end mobile devices with some optimizations. See Unity’s WebGL browser compatibility.
