Cannot take screenshot of AR scene

Description: I am developing web AR using aframe but I cannot get screenshot of gameplay. It’s wired. My web AR project is to place object on the floor markerless.

Platform / Device: Android

         </a-sphere>
    </a-scene>

In some AR, I can see video tag to show streams from webcam but in this markerless AR, I cannot see video tag. so I cannot merge picture from video and picture from 3d enviroment. Also I am using dom-overlay to show some UI buttons.

Feature request to implement a WebXR screenshot feature on the model-viewer itself: https://github.com/google/model-viewer/issues/1481

It also depends on the WebXR standard to expose the camera feed that it’s not available at the moment.

What the model viewer is doing is opening the Android built-in native Scene Viewer via an intent. It’s a separate app that offers a simple way to preview 3D models (Web APIs constraints don’t apply in that context). It’s equivalent to the Quick Look viewer on iOS for USDZ models.
