SceneKit Textures
<p>I'm trying to learn SceneKit for iOS and get beyond basic shapes. I'm a little confused on how textures work. In the example project, the plane is a mesh and a flat png texture is applied to it. How do you "tell" the texture how to wrap to the object? In 3D graphics you UV unwrap, but I don't know how I would do this in SceneKit.</p>
