I felt difficulty following the instruction written in page 55 in the PDF edition. I finished Victoria Wenderlich’s tutorial on Blender but still could not figure out how I can expose the Node inspector in Blender. I kept playing on Blender’s object inspector and was confused from small differences in visual appearance between what I see in Chapter 2 and my Blendor view. It was only after spending some time on Google that I realized what I see Object inspector in the book refers to the Xcode SceneKit editor view. In fact, I have been thinking that SceneKit refers to the right pane of Blender.
I believe a bit more text addition could have greatly helped me and others who are new to Xcode and 3D modelers.
