Collection Source

Loads one or more collections from the current .blend file and makes them available to downstream nodes.

When to use it

Use Collection Source when the collections you want to render are in the same .blend file as your node graph. For collections in external files, use External Collection instead.

Outputs

Socket	Description
Collection	The loaded collection, ready to connect to a Scene node or override node

Properties

Each entry in the node represents one collection. Click Add Collection to add entries; click × to remove one.

Collection picker — click the field and select a collection from your scene. The picker shows all collections in the current file. The reference follows renames automatically — if you rename the collection in the Outliner, the node updates itself.

Enable toggle — the checkbox to the left of each entry enables or disables that collection. Disabled entries are ignored during rendering.

Using multiple collections

You can add as many collection entries as you like to a single Collection Source node. All enabled collections are passed downstream as a single output. This is useful when several collections always travel together as a group.

If you need to apply different overrides to different collections, use separate Collection Source nodes instead.

Tips

• If a collection reference turns orange or shows an error in the Warnings panel, the collection was likely deleted or renamed to something that couldn't be resolved automatically. Re-select it in the picker.
• Collections linked from an external file using Blender's standard link system appear in the picker and work normally.
