Hello Jeremy,

Which branch of the qt3d repository are you using ?

Right now we're mostly working on the 5.6 branch, a few issues that you've 
encountered might have already been fixed.

What you are doing looks correct to me. Maybe doing a setProperty doesn't 
trigger a notification signal when the property changes.

Could you verify that when you change the value of the positionX property from 
C++ it triggers a positionXChanged signal. Simply adding an 
onPositionXChanged: console.log("posXChanged") 
on the Entity and 
onTranslateChanged : console.log("translation " + translation)
on the Translate .

in the qml would be enough to verify this.

You can file a bug report and assign it to me otherwise.

Setting the enabled flag on a QAbstractMesh component stops it from being 
rendered. This was fixed only a few weeks ago (QTBUG-48630). You do not need to 
handle it in your QAbstractMesh subclasses.

You've got two ways of doing so:
Either use a QCamera/Camera and call the tilt/pan/roll/rotate/translate using 
a QKeyboardInput component.

Or have a QEntity with a QTransform { QLookAtTransform {} } and a QCameraLens 
and do the same thing by modifying the properties on the QLookAtTransform 

The Camera controller that is available by default uses hard coded keys. We 
are actively working on that part and will later provided out of the box 
camera controllers for 1st and 3rd person.

You can join the #qt-3d irc channel and ask questions on here.
