Explorer Window

The Explorer window shows a hierarchical list of every instance inside an experience. At the highest level of the hierarchy are the services; Workspace, for example, is where visible 3D content such as parts are stored.

Parent-Child Hierarchy

Roblox uses the concept of parenting to organize objects. All children of a parent object appear under its branch when expanded.

Expanding and Collapsing Branches

Clicking the arrow next to a parent branch, or pressing or when a parent is selected, expands or collapses only that branch (nested child branches remain in their current state). To expand or collapse all branches within a multi-nested hierarchy, hold Shift when clicking the arrow.

Inserting and Parenting

Insert New Object

Some objects like primitive parts can be inserted from the Model tab, but a full array of objects can be inserted through any of the following methods:

  • Hover over the object's parent and click the ⊕ button.

    Hovering over Workspace object to reveal insertion button
  • Right-click the object's parent and select Insert Object.

  • Select the object's parent and press CtrlI on Windows or I on Mac.

Each method opens an insertion window which contains a list of objects, sorted by category. You can quickly locate familiar objects by typing a search query in the input field:

You can further customize the behavior of the insertion workflow as follows:

Additional customization buttons for insertion workflow
  • Expanded View shows a much wider window to select objects from.
  • Insertion Settings contains the following toggles:
    • Select object after insert automatically selects new objects after you insert them.
    • Show only recommended objects limits the list of objects to those which are logical or functional within the parent.

Paste From Clipboard

For an object copied to the clipboard, you can paste it as a new child to the Workspace, or into one or more existing parents.

  • Press CtrlV on Windows or V on Mac to paste the object into the top-level Workspace.

  • Right-click specific parent(s) and choose one of the following options from the context menu:

    Paste IntoPastes the child geometrically on top of the original.CtrlShiftV (Windows)
    ShiftV (Mac)
    Paste Into at Original LocationPastes the child at the same CFrame it was authored at.

Changing Parents

To change the parent of one or more children (reparent), simply drag and drop them onto the new parent.

Organizing by Folders

Like directories/folders on a computer, the Folder object is a useful way to organize objects. For instance, if you want to store all environmental sounds in a logical place, you can create a folder and place multiple Sound objects within it.

Multiple Sound objects grouped inside a Folder object

You can organize objects into folders as follows:

  • Create a Folder instance through a standard insertion method, then drag and drop existing objects into it.

  • Select multiple objects, right-click them, and then select Group as a Folder from the context menu or press AltCtrlG on Windows or G on Mac.

Filtering Instances

Through the Filter Workspace input near the top of the window, You can filter instances by name, property, class/subclass/tag bespoke queries, and ancestry queries. You can also combine parameters for advanced logical filtering.

Name Filter

Typing in a basic string yields name matched instances. For example, filtering by the keyword "script" finds all instances containing it, such as ServerScriptService and StarterPlayerScripts.

Objects filtered by query of 'script'

Property Filters

You can filter by property equality or value comparisons. Most properties are supported, and the filter works with partial matches, ignores spacing, and is non-case-sensitive.

  • Property equality is filtered through the operators = or ==.

    Example FilterResult
    Locked = trueBaseParts with Locked set to true.
    Material == plasBaseParts with Material of either Plastic or SmoothPlastic.
  • Property value comparisons are filtered through the operators ~=, >, <, <=, or >=.

    Example FilterResult
    Health > 50Every Humanoid with more than 50 Health.
    Transparency ~= 0.5BaseParts with Transparency not equal to 0.5.
  • Property types such as Vector3 and Color3 support filtering on individual fields. This works either for exact equality or for value comparisons.

    Example FilterResult
    Position.X = 1Objects with an X position of exactly 1.
    Color.R > 120Objects with a red (R) color channel value greater than 120.
  • Property types such as Vector3 and Color3 support filtering as a complete unit, with the unit surrounded by quotes. This works either for exact equality, or with comparison operators in which every value is compared against the comparator.

    Example FilterResult
    Size > "20, 5, 20"Objects with an X, Y, and Z size greater than 20, 5, 20, respectively.
    Color = "255, 0, 0"Objects with an RGB color value of exactly [255, 0, 0].

Bespoke Filters

Classes, and subclasses, and tags are filtered through various bespoke queries, including:

  • classname:[Class] and c:[Class] both find everything that is of class [Class]. For example, classname:Part finds everything that is a Part.
  • is:[SubClass] finds everything that is a subclass of [SubClass]. For example, is:BasePart finds everything that is a subclass of BasePart, such as Part and MeshPart.
  • tag:[TagName] finds everything with a CollectionService tag of [TagName]. For example, tag:LightSource finds everything that is tagged LightSource. You can add tags using the Tags section of an instance's properties, or Studio's Tag Editor, and tag names will autocomplete.

Ancestry Filters

You can filter within a specific scope using the . operator, chain operators together for highly specific filters, or use * as a wildcard.

  • [Parent].[Child] finds named children inside a named parent. For example, workspace.Model finds instances named Model inside instances named workspace, similar to scripting.

  • Chaining . operators adds specificity. For instance, Animals.Dog.Tail finds objects named Tail inside Dog inside Animals.

  • * acts as a wildcard, for instance:

    Example FilterResult
    Cart.*All children of an object named Cart.
    Cart.Barrier.*All children of Barrier, itself a child of Cart.
    Cart.*.*All grandchildren of Cart, excluding direct children of Cart.
    Cart.*.TrimAll grandchildren of Cart that are named Trim.
  • [Parent].** finds all descendants of a parent. For example, CarModel.** finds all descendants of CarModel.

Combining Parameters

For advanced logical searches, you can combine filters through unions and grouping.

  • Multiple filters separated by spaces or and operate on all of the conditions.

    Example FilterResult
    Anchored=true CanCollide=trueEvery BasePart that is anchored and can collide.
    Cart.*.* Transparency < 1All grandchildren of Cart that are not fully transparent.
    Anchored=false and CanCollide=falseEvery BasePart that isn't anchored and can't collide.
  • The or conjunction operates just like the or operator in code. Groups within parentheses, conjoined by or, find everything within multiple combined filters.

    Example FilterResult
    Cat or DogEverything that has Cat or Dog in its name.
    (Anchored=true CanCollide=true) or (Anchored=false CanCollide=false)Every BasePart that either is anchored and can collide, or isn't anchored and can't collide.

Selecting Filtered Results

Within a filtered hierarchy, certain key shortcuts and mouse operations behave differently than they do within a non-filtered hierarchy.

Select All

Within a non-filtered hierarchy, pressing CtrlA on Windows or A on Mac selects all objects. Within a filtered hierarchy, the same shortcut or the "select all" button selects only the filter-matching objects.

All objects selected with Select All shortcut
All objects selected


Within a non-filtered hierarchy, clicking an object and then Shift-clicking another object selects everything within the range.

Within a filtered hierarchy, if both the initially clicked object and the Shift-clicked object match the filter query, only filter-matching objects within the range are selected.

All objects selected with Shift-select key combo
All objects in range selected

Drag Select

Clicking and dragging from the right side of the window initiates a selection box. Within a non-filtered hierarchy, everything within the box is selected.

Within a filtered hierarchy, only filter-matching objects within the selection box are selected.

All objects selected with mouse drag-select
All objects within selection box selected

Additional Key Shortcuts

With a collapsed branch selected, expands that branch. When pressed again, selects the first child immediately under the parent node.
With any child of a branch selected, moves selection back to the parent node. When pressed again, collapses the entire branch.
homeSelects the topmost object in the hierarchy (Workspace).
endSelects the bottommost object in the hierarchy.
page upSelects the object in the hierarchy that's above the topmost visible hierarchy item.
page downSelects the object in the hierarchy that's below the bottommost visible hierarchy item.
