See in Glossary in a scene, including models, cameras, and prefabsAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
See in Glossary. You can use the Hierarchy window to manage and group the GameObjects you use in a scene. When you add or remove GameObjects in the Scene view, you also add or remove them from the Hierarchy window.
You can open more than one scene in the Hierarchy window at the same time, with each scene containing its own GameObjects. To learn more, refer to Work with multiple scenes in Unity.
The Hierarchy window can also display items that aren’t GameObjects, such as UI Toolkit visual elements. To learn more about displaying visual elements in the Hierarchy window, refer to the Reference visual elements.
