Object Tree

The Object Tree lists all active objects in the scene. Objects added from the Standard Asset library or imported from files appear in the tree. From here you can navigate the hierarchy, select and rename objects, duplicate or copy/paste them, and edit parent-child relationships.

Create empty objects

Click the + button near the Objects title to create an empty object. Empty objects are created at world position (0, 0, 0) with identity rotation.

Add standard assets

Click the + button near the Objects title and choose Asset Library.

Use the library to:

• Search assets by name or reference
• Filter by category (for example Robot, Machine, Conveyor, Linear axis, or Gripper)
• Filter by brand
• Select an asset card to add it to the scene

After adding an asset, it appears in the object tree and can be edited like any other scene object.

Select objects

Click an object to select it. The selected object appears in bold. Only one object can be selected at a time.

Rename objects

Right-click an object and choose Rename. The name becomes editable. Multiple objects can share the same name.

Delete objects

Right-click an object and choose Delete. The object and all of its children are removed.

Change parent-child relations

To change parent-child relations, drag an object onto another object to make it a child of that parent.

Reparenting can change the object's transform because its position becomes relative to the new parent.

To keep the object in the same world position when reparenting, drag it while holding CTRL+R.

Create empty childs or parents

Right-click an object and choose Create Empty Parent or Create Empty Child.

This creates a new empty object at the same transform as the selected object and places it in the hierarchy according to the option you chose (as a parent or as a child).

Change object visibility

You can control object visibility in the scene by toggling the eye icon next to each object in the hierarchy.

If a parent object is hidden, all of its child objects are hidden as well.

Export as prefab

Right-click an object and select Export as Prefab.

This is especially useful for building complex systems. You can create and validate assemblies in one project, export them as prefabs, and reuse them in other projects.
