Getting ready

For this recipe, we have prepared the BasicScene Unity package, containing a scene named BasicScene, and also two FBX 3D models for the monitor and camera objects. The package is in the 1362_05_codes folder, and the 3D models are in the 1362_05_06 folder.

To create a picture-in-picture display, just follow these steps:

1. Import the BasicScene package and the monitor and camera models into your Unity Project.

2. From the Project view, open the BasicScene level. This is a basic scene featuring an animated character and some extra geometry.

3. From the Project view, place the monitor and camera...
