In this chapter, you took all your assets from SketchUp and made them into a walkthrough game. You learned how to set up your environment in Unity 3D. You learned how to create a realistic backdrop with an alpha map which you clipped in Unity to make parts of it see-through. You set up a skybox so that you could see clouds and sky above the buildings in the background and above you. There’s been a lot to do in the chapter, but now you have a finished level. You can be proud of your achievement.
