This chapter took our starting scene a big step further. Lighting is essential in architectural visualization and Unity provides several options to tweak and improve the visual quality of your scene.
While you can get quite far with the free version, lighting with the pro-version is more advanced with Area lights, Bounced lighting, and Sky lights to improve Lightmapping results. In addition, the full screen image effects give a more polished effect to the result. Luckily for the users of the free version, real-time hard shadows were added for Directional lights in Unity 4.2, which could be used in any architectural scene. But use them sparingly, when you need interactive lights.
The next chapter looks at navigation in our project, using character controllers.
