How to create realistic .scn files? : <p>Looking at the apple sample AR app, there are many realistic looking objects (cup, candle, etc). However working with the scene kit editor on Xcode it is clear that this only allows you to create basic objects. </p>

<p>My question is, what software/file can be used to create realistic <code>scn</code> objects? I'm sure that there is software that allows you to create 3D models and covert them to <code>scn</code> files. I just don't know which software to use or what files can be converted to <code>scn</code></p>

<p><strong>Note:</strong> I understand that this question may be too vague/broad for the Stackoverflow guidelines. I just don't know where to pose my question and this seems like the best place</p>
