Scene Hierarchy Panel

The Scene Hierarchy panel displays all user entities in your scene as a flat list. Use it to create, select, delete, and duplicate entities.

Entity List

Entities are displayed as leaf tree nodes (no expand arrows). The panel filters to show only user entities, excluding internal engine entities. When the scene is empty, a "No entities in scene" message appears along with a Create Empty Entity button.

Click an entity to select it — the selected entity is highlighted and its components appear in the Inspector.

Creating Entities

Empty Entity

Click the Create Empty Entity button at the top of the panel, or right-click on blank space and choose Create Empty Entity. This adds a new entity named "New Entity" to the scene.

3D Primitives

Right-click on blank space in the panel and open the 3D Object submenu to create an entity with a Transform and ModelRenderer pre-configured:
