Unity Certified User Artist Tests and Training Practice Test

You can have any number of cameras in a Unity scene. Each camera provides its own viewpoint and can render a different set of objects by using its culling mask, clear flags, and depth. This lets you compose scenes by layering multiple cameras—for example, one camera rendering the game world and another rendering UI or a minimap—so their outputs are combined in the final image. In modern Unity pipelines, camera stacking further clarifies how base and overlay cameras work together to build the final view. The practical limit isn’t a hard cap in the engine; it’s determined by performance and how complex the scene becomes.
