Graph (Scene Hierarchy)

The Graph window shows the object hierarchy of the currently loaded scene as a tree. It is the main place to organise objects, parent them to each other, and manage the scene structure. Selection is shared with the 3D Viewport and the Object inspector.

The tree

Each row represents one object. The icon in front of the name hints at its role: a prefab marker for prefab instances, the icon of its first component, or a generic cube / scene-root icon when it has none.

Clicking a row selects the object. Selecting in the viewport highlights the matching row here, and vice versa.

Row controls

On the right of each row are two toggles:

Toggle	Description
Selection	Whether the object can be picked in the viewport.
Enabled	Whether the object (and its children) is active in the scene.

Editing the hierarchy

Action	Result
Double-click a name	Rename the object inline.
Drag a row onto another	Re-parent the object under the target.
Drag between rows	Re-order, or insert at that position.
Right-click a row	Open the context menu.

The context menu offers:

• Add Object: add a new empty child object.

• To Prefab: turn the object into a prefab asset (not shown for prefab instances).

• Delete: remove the object and its children.

All of these are recorded in the undo history.
