Selecting multiple collections & all objects inside them It is possible to right click in the outliner on the collection &gt; select objects. I would also like to select all my objects from another collection. Right clicking and &gt; select objects automatically deselects my previously selected objects. Is there a way to select multiple collections and their content?
YES.
Create a new collection.
Drag-drop the other collections inside it.
Right-click top collection --&gt; Select Objects.
