3D Models and Hotspots

[13057]

Hi guys. I'm new to QML and having a few issues that I hope you guys can help me with. I have a 3D model in a .dae file that I am trying to display. I can display it in Qt 5.4 by:

import QtQuick 2.0
import Qt3D 2.0

Rectangle {
width: 1140
height: 700
color: "white"

Viewport{
id: viewport

anchors.fill: parent
camera: Camera {
eye: Qt.vector3d (400.0, 100.0, -400.0)
fieldOfView: 90
}

Item3D{
id: satellite
mesh: Mesh{source: "ow.dae"}
position: Qt.vector3d(0, -0, 0)
}

light: Light{
position: Qt.vector3d(1000, -1000, -1000)
}}}

I have tried to display the same model in Qt 5.7 but all my attempts have been unsuccessful. Would any of you guys happen to know how to do it?

Also, I would like to put hotspots on the model, that display information about a particular point on the model. However the only text I can find online, mentioning hotspots, is outdated. Is it possible to put hotspots on a model and if so, how can it be done in either 5.4 or 5.7?

Thanks for your help.
