Hierarchy & Inspector
Organize the current scene and edit entities/components with stable serialized data.
#Hierarchy
The Hierarchy shows only entities that belong to the active scene. Entities can also belong to hierarchy folders. The saved scene stores folders separately so folder IDs remain stable across save/load.
#Inspector
The Inspector edits the entity name, tag, active state, component properties and component-specific authoring fields. For many components, the Inspector exposes more authoring fields than the runtime script API intentionally does.
#Gizmos and shapes
Spatial editing uses scene-view gizmos for things such as triangle collider/shape points and other editable geometry. Treat these as authoring controls; scripts should use the documented component APIs instead of manipulating editor gizmo state.
