Starting a new, basic AR scene

In this section, we'll create a scene very similar to SimpleAR (actually, more like the Samples scene named InputSystem_PlaceOnPlane) but we will start with a new empty scene. We'll add AR Session and AR Session Origin objects provided by AR Foundation to the scene hierarchy, and then add trackable feature managers for planes and point clouds. In the subsequent sections of this chapter, we'll set up an Input System action controller, write a C# script to handle any user interaction, and create a prefab 3D graphic to place in the scene.

So, start the new scene by performing the following steps:

1. Create a new scene by going to File | New Scene.
2. If prompted, choose the Basic (Built-in) template. Then, click Create.

   Unity allows you to use a Scene template when creating a new scene. The one named Basic (Built-in) is comparable to the default new scene in previous versions of Unity.

3. Delete Main Camera from the Hierarchy window...
