QRenderCaptureReply returns a screenshot with a background and no model

qingcheng

 auto camSelector = this->defaultFrameGraph()->findChild<Qt3DRender::QCamera*>();
 m_cap = new Qt3DRender::QRenderCapture(camSelector);
 connect(this, &Q3DShowWindow::signalGetImage,[&](){
    QEventLoop loop;
    auto reply = m_cap->requestCapture();
    qDebug()<<"wait for m_returnimage finish";
    connect(reply, &Qt3DRender::QRenderCaptureReply::completed, [&] {
        m_returnImage = reply->image();
        qDebug()<<"ok in loop";
        reply->deleteLater();
        loop.quit();
        });
    loop.exec();
    });

Above is a screenshot of a scene I used QRenderCaptureReply to get, but m_ReturnImage only gets the background of the scene.
Why is that? Did I miss something?

Hi,

Please do not post the same question in multiple sub-forum. One is enough.
