Outliner filter or sort by object type? Is there anyway to filter by object types not separated by layers? For example, i have an imported scene with many cameras, and I would like to see all cameras in now list.
In 3d View select 1 object of your desired type (Camera, Light, Mesh etc.)
Go to the Outliner and select Same Types from the dropdown menu


This will display all objects in your scene based on the current selection. E.g. When a camera is selected, the outliner will display all available cameras in your scene:
