Studio Overview – Explorer Window

The Explorer window shows a list containing every Instance inside of a Place. It can be toggled from the View tab.


Parent-Child Relationship

The Explorer window uses the concept of parenting to organize all of the instances hierarchically. If an instance has any children, it will show a small arrow next to its name. Clicking on this arrow toggles a list of all the children of that instance.

Here, Model and Part are on the same level; neither is parent to the other — both are parented to Workspace.

In this example, Part is a child of Model. Likewise, Model is the parent of Part.

Default Explorer Organization

At the base level, the Explorer is organized into several categories and services.

Category / Service Description
Workspace Contains all of the visible objects in the Place. If you want a Part or Model to appear in the game and be affected by the game's physics and other systems, it should be in here.
