QDeclarativeView3D black screen while loading 3D model

[Bobbz]

Hi all,

I'm writing a QtQuickApplication, in which there should be a box showing a 3D model made in 3ds.
I took a QML project online that does this job, using a .qml file with this simple piece of code:

@import QtQuick 1.0
import Qt3D 1.0
import Qt3D.Shapes 1.0

Viewport {
Mesh {
id: cube
source: "cube.3ds"
}

Item3D {
    mesh: cube
}

}@

I run this qml project, and everything works fine.

I decide then to import this "sample.qml" file inside my Desktop application, as explained in http://doc.qt.nokia.com/4.7/qml-inte...objects-in-qml. To do so, I promote a QGraphicsView to a QDeclarativeView3D, and in the main cpp file I write:

@
ui->graphicsView->setSource(QUrl::fromLocalFile("sample.qml"));
ui->graphicsView->show();
@

where ui->graphicsView is obviously the QDeclarativeView3D widget.

Now, there's the problem: I run the application, but the QDeclarativeView3D remains always black, even "mousing" over it.
I also tried giving graphicsView an inexisting file as source, but in that case the QDeclarativeView3D is white: then, is almost sure that the qml file is loaded. I wonder why it can't be shown.

Any suggestion will be appreciated!

Thanks in advance,
Bobbz

Have you tried running with -graphicssystem opengl?

Thanks for suggestion. Unfortunately, it doesn't work...
