This header dropdown lets you choose what the Outliner should show.
Shows theview layers,collections,and objects across all scenes.
Shows the collections and objects in the current view layer of the current scene.
Shows the images and videos that are used in theVideo Sequencer.
Lists all data in the current blend-file. On the right side of the list, a shield icon shows the numberof users – clicking it adds or removes afake user.
Lists everydata-block in the file along with any properties that it might have.
Shows thelibrary overrides.Separated further into two view modes:
Shows the data-blocks that have overridden properties in a list grouped by type.You can expand each data-block to see and change these properties.
Shows the overridden data-blocks in a tree that visualizes their hierarchy.This includes parent data-blocks that were overridden implicitly.For example, if you created an override for a material,this tree would show the hierarchy object > mesh > material.
This view also shows a column of icons on the right that let you toggle whethereach override is editable.
Lists the data-blocks that are unused or only have afake user.You can add/remove a fake user by clicking the shield icon on the right.
Unused data-blocks are automatically deleted when saving and reloading the file.You can also delete them manually by clickingPurge in the header.
The textbox lets you filter the tree by typing a substring. You can focus it usingCtrl-For clear it usingAlt-F.
The funnel icon in the header offers further control over what is displayed in the editor.Depending on theDisplay Mode, some options are not available.
Set whichRestriction Toggles should be visible.
Sort the entries alphabetically.
Whether to synchronize the Outliner selection to and from the3D Viewport andVideo Sequencer editors.
Show the column for toggling theobject interaction mode.
Search
Only show the items whose name fully matches thesearch textrather than only containing it as a substring.
Take lower/upper case into account when comparing the search text to the item names.
Filter
Show all theview layers in the scene instead of only the active one.Combined with disabling theObjects filter, this gives a compact overview of all the collections in relationto the view layers.
Show the collections in the scene hierarchy. Only the collections themselves are hidden when this optionis disabled; the objects within them remain visible.
Show the objects in the scene hierarchy. Disabling this gives you an overview of just the collections.
List the objects based on their state or restrictions.The results can be inverted using theInvert toggle button.
Show all objects.
Only show the objects that are visible in the 3D Viewport.This takes both theHide in Viewports andDisable in Viewports settings into account;seeRestriction Toggles.
Only show the object(s) that are currentlyselectedin the 3D Viewport.
Only show the active object (typically the one that was selected last).
Only show the objects that can be selected in the 3D Viewport;seeRestriction Toggles.
List relevant materials, modifiers, mesh data and so on as children of each object.
Showchild objects as child nodes in the Outliner tree.When disabled, child objects are shown as sibling nodes instead (unless they’re in a different collectionthan their parent, in which case they’re not shown in the parent’s collection at all).
Lets you filter out objects by type.
Shows the data-block properties that are defined/controlled automatically (e.g. to make data-blockspoint to overridden data instead of the original). Only available in theLibrary OverridesDisplay Mode.
Some options in the header will only show if compatible with the activeDisplay Mode.
Add a new collection inside the selected one.
Restrict the type of the data-blocks shown in the Outliner.
Add/Remove the selected property to/from the activeKeying Set.
Add/RemoveDrivers to the selected item.
Opens a dialog to remove unused data-blocks from both the current blend-file or anyLinked Data (cannot be undone).
Removes unused data-blocks from the current blend-file.
Removes unused data-blocks fromLinked Data.
Removes data-blocks only used by unused data-blocks,ensuring that no orphaned data-blocks remain after execution.

Mode icons. Two objects are currently in Edit Mode; a third could be added.¶
If a selected object is in aninteraction modeother than the default Object Mode, the Outliner shows an icon representingthis mode on the left.
If the active object has such an icon, the Outliner also shows a dot next toobjects of the same type. You can click such a dot to switch over to a differentobject while staying in the same mode.
If the mode supportsMulti-Object Editing, you can also click adot withCtrl-LMB toadd an object to the mode.
You can click the mode icon of the active object to switch it (and any other objectsin case of Multi-Object Editing) back to Object Mode. You can alsoCtrl-LMBthe mode icon of a selected – but not active – object to switch only that objectback to Object Mode.

Restriction toggles.¶
The right side of the Outliner shows a series of toggle icons for every collection,object, bone, modifier, and constraint. These can be used to make the item invisible,unselectable, and so on.
Note
Only a few icons are shown by default. You can use theFilter pop-over toshow additional ones.
Clicking an icon withShift-LMB toggles it for the item and all its children.
Clicking a collection’s icon withCtrl-LMB enables it for the collection (and itsparent/child collections) and disables it for all others. Clicking again enables it for the others again.
Toggles the collections inclusion in the currentView Layer.When excluded, contents will be hidden in the 3D Viewport, the render, and the Outliner.SeeInclude for more information.
Toggles whether the object or collection can be selected in the 3D Viewport.This can be useful for, say, references images that you only want to display and never select/move.
See more information for:
Toggles the visibility of the object or collection in (only) the 3D Viewport, for the current view layer.The render is not affected.
As an alternative to clicking this icon, you can pressH while hovering over the3D Viewport to hide the selected objects, orAlt-H to unhide all objects.
This setting only applies within the current blend-file: when youLink or Append it to anotherblend-file, all collections and objects will be visible there.
Objects hidden this way are still part of the view layer,so they still get evaluated and affect playback performance.
See also
Collections can be hidden for individual 3D Viewports;seeLocal Collections in the Sidebar.
Toggles the visibility of the object or collection in (only) the 3D Viewport, for all view layers.The render is not affected.
This setting is separate fromHide in Viewports. An object needs to have both settingsenabled to be visible. You can use this one for “long-term invisibility,”keeping an object invisible even after pressingAlt-H.
This setting carries over to other blend-files when linking or appending.
Objects hidden this way are no longer part of the view layer,so they no longer get evaluated and don’t affect playback performance.
Toggles the visibility of the object or collection in (only) the render,for all view layers. The 3D Viewport is not affected.
This is typically used for supporting objects that help modeling and animationyet don’t belong in the final image.
Toggles the collection’sHoldout property,which makes the objects in the collection cut a fully transparent hole into the render output of the view layer.
Toggles the collection’sIndirect Only property,Objects inside this collection will only contribute to the final image indirectly through shadows and reflections.
