QtQuick 3d: how to enable transparency?

[hhrhhr]

if in the tutorial "\tutorials\qt3d\penguin_advanced":http://doc.qt.nokia.com/qt-quick3d-snapshot/qt3d-penguin.html load model with a transparent material, it appears as a normal material. ("test model":https://github.com/assimp/assimp/blob/master/test/models/3DS/cubes_with_alpha.3DS)
how to enable the transparency?

Apparently the Qt Quick 3d importer is still incomplete and doesn't handle transparency yet. You sometimes work around this from within the QML file.

Try having a look at "this video":http://labs.qt.nokia.com/2011/08/24/qt-quick-3d-tutorial-video/ . They cover "fixing" the glass in a car model so it is semi-transparent.

Hopefully that might be of some use.

Thanks, I tried to do it in Qt3D and everything turned out (add an transparency effect to the individual mesh).
but usually the editing model is difficult :(
