Creating a Camera in a Scene
To create a new Camera go to the Properties Panel of the Scene, and in the Outliner, click on the Add button, then hover your mouse over Cameras:
You have the choice between a Perspective Camera and an Orthographic Camera
The Camera Type can be changed at any time in the Properties of the Primitive, below the Scene Graph:
The Type seen in the Scene Graph is a USD Type, and the name may differ with the chosen camera. For example, a Perspective Type doesn't exist in USD, but can be made using specific attributes on a Camera Type!
