Adding background characters

An easy addition that we could quickly make is background characters. Even though we already have our animated sequence done, having background characters can liven up the environment even more. It’s great to have a main cast, but just having people in the background who are talking and taking up space can make the environment feel a lot more immersive and fuller as opposed to having a big open space that feels lifeless. We can revisit the People_Prototype prefab that we made and add audio sequences and animations, as well as replace the 3D model with the X Bot and Y Bot models that we downloaded. The best part about these models is that we can switch up the materials on them, giving them a variety of different looks.

To replace our People_Prototype prefab with a 3D model, follow these steps:

1. In the Prefabs folder, double-click the People_Prototype prefab to open it.
2. Find the X Bot 3D model and add it as a child of the People_Prototype...
