At this point, you should feel capable of manipulating GameObjects, adding components, importing models and textures, and configuring materials in the Editor. Hope you've come to appreciate Unity even more after you've witnessed how simple this engine actually is. If you need more information on how to handle importing objects from any specific 3D app, you can always reference the official documentation available at http://docs.unity3d.com/Manual/HOWTO-importObject.html.

If you wish to learn more about materials and physical-based shading, I would direct you to the official tutorial at www.youtube.com/watch?v=fD_ho_ofY6A.

In the next chapter, we will look into Unity's built-in Terrain system and how to use it.
