A Camera in Unity works like a camera in the real world: it captures a view of objects in 3-dimensional space and flattens that view to display it on a 2-dimensional surface.
Cameras in the Universal Render Pipeline (URP) are based on Unity's standard Camera functionality, but with some significant differences. The most notable ways in which Cameras in URP differ from standard Unity Cameras are:
- The Universal Additional Camera Data component, which extends the Camera component's functionality and allows URP to store additional Camera-related data
- The Render Type setting, which defines the two types of Camera in URP: Base and Overlay
- The Camera Stacking system, which allows you to layer the output of multiple Cameras into a single combined output
- The Volume system, which allows you to apply post-processing effects to a Camera based on a given Transform's position within your Scene
- The Camera component, which exposes URP-specific properties in the Inspector
