If Blender helped you with your projects this year, we're asking you to help us back.
For the past year, you've had access to professional 3D software, completely free. No subscriptions, no licenses, no limits. Blender has been there for your projects, your learning, your art, your business.
Today, we're asking for $5.
That's it. If every active Blender user contributed $5 this month, Blender Foundation would meet its entire yearly funding goal for 2026.

As above, but also affects child collections/objects. Note that if you run this on a collection,child objects that (also) belong to another collection will not be deleted.
Adds the items that are selected in the Outliner to the selection in the 3D Viewport. This is onlyuseful whenSync Selection is disabled,as when it’s enabled (which is the default), the Outliner selection is synchronized to the3D Viewport automatically.
Adds the children of the selected items to the selection in the Outliner. IfSync Selection is enabled,this also adds them to the selection in the 3D Viewport.
Removes the items that are selected in the Outliner from the selection in the 3D Viewport.
Removes the current usage of the data-block while keeping any others. Objects are only removedfrom the current scene, materials are only removed from the current mesh, and so on.
Collections let you organize the content of a scene.They can contain objects as well as other collections.
Creates a new collection.
Recursively duplicates the collection including all child collections, objects, and object data.
Recursively duplicates the collection including child collections and objects,but reuses object data.

Copies/pastes selected data-blocks.
Adds/removes afake user, which prevents unused data-blocksfrom getting automatically deleted when saving and reloading the blend-file.
