It is possible to right click in the outliner on the collection > select objects. I would also like to select all my objects from another collection. Right clicking and > select objects automatically deselects my previously selected objects. Is there a way to select multiple collections and their content?

In the outliner select your first collection, Right-click and 'Select Objects'. THEN, Ctrl-click the second collection (Previous selected objects should remain selected), Right-click and 'Select Objects' again. Now all objects from both should be selected.

Create a new collection.

Drag-drop the other collections inside it.

Right-click top collection --> Select Objects.

  • $\begingroup$ Instead of drag-dropping collections, it's better to create a new tmp collection, and linking (shift + m) to it all objects we want to select in once ; this allow to not mess up our hierarchy. $\endgroup$

    $\begingroup$ Is this really the only way to do this? It seems like there should be a better way! $\endgroup$
