title: How to change the texture or colour of an object in Qt3D with QML?
body: <p>I have a project, where i have one 3d object (.obj file) and i want to click on this object. For the first test i would be happy to change the texture or colour of the object. As far as i know it's called picking. Do you guys know how to manage this in qt3d? My whole project is written in qml, so it would be great if i could do the picking with qml (without c++), but if it's necessary im ready to try it that way, too.</p>
  
  <p>My project is structured as followed:</p>
  
  <p>I have an Entity as rootEntity and 3D-Entity, where my mesh is loaded. This structure is in an own qml file called View3d.qml. Now I set a Scene3D in my main.qml and load setup an instance of View3d.</p>
  
  <p>I am using the Qt 5.5 beta with included qt3d on a windows 8.1 64Bit system, if its necessary.</p>
