I’m at the end of Section 1, Chapter 2, trying to change the position of the train. It says: “Select train.obj in the Project navigator; this will show you the train model in the SceneKit editor. Now, click on the train to select it.”
But when I select train.obj in the Project navigator, I end up with a blank scene in the SceneKit editor. Moreover, when I open the Scene Graph, I see no nodes: Just an empty pane.
Ideas? I’ve never tried to view an obj with Xcode, so maybe I’m missing something simple. The file itself does show a preview in the Finder, and it does have data when I view it in TextEdit.
