Introduction¶
In Blender, objects are not directly part of the scenes. Instead, they all get stored in a main database (basically the blend-file).
From there they are referenced into as many Scenes as you would like to see them.
When they are stored in a scene, they are part of a so-called scene collection. So ultimately all the scene objects belong to this special collection.
Collections¶
While the scene collection contains all the Scene’s objects, the user can also make their own collections to better organize these objects.
It works like a Venn diagram, where all the objects are part of the scene collection, but can also be part of multiple collections.
The result is a clear and flexible way to arrange objects together on the Scene level.
Naming and Nesting¶
Collections can be named and sorted hierarchically. Just like folders can have subfolders in any operating system, collections can have nested collections too.
For example: a house collection can contain a bedroom collection, which in turn contains a furniture collection referencing a bed, a cabinet and other objects.
