Hi As stated above, explicit setting the camera in View3D will make mapTo3DScene() work, but it will break the View3D display content. I have created a bug report

Picking works with regular Models (Sphere, Cube, ...) but fails with my custom model. IIRC picking is still not implemented in custom models ? Does anyone know current status of picking, if it is planned for Qt 6.2 ? For now I will implement my own picking for custom models wich leads to my second question: I'm getting an error trying to use View3D.mapToScene( ), my code is something like: View3D { id: view ........... OrthographicCamera{ id: mainCamera z: 300 } ...........} MouseArea { id: ma anchors.fill: view onMouseXChanged: { var pos3D = view.mapTo3DScene(Qt.vector3d(mouseX, mouseY, 0)) console.log("pos3D: "+pos3D) }} The error:QML View3D: Cannot resolve scene position without a camera assigned! Am I misunderstanding how to use mapTo3DScene, is this a bug, or what am I missing ?
