    Currently having trouble drawing qml elements above a scene graph. I have tried changing the z values of the scene graph itself and of the element I want drawn over with no success.

    Thank you for any help, and I can give more details if needed!

      Hi and welcome to devnet,

      Do you mean something like described in the OpenGL under QML example ?

        Hi @Pheelbert,
        Make use of QQuickWindow::beforeRendering signal to draw the OpenGL stuff beneath QML scene.
        Have a look at this flow for more info, especially Pt. no. 8 and the example suggested by @SGaist.
