Activation#

  • Open Blender and go to Preferences then the Add-ons tab.

  • Click Interface then Collection Manager to enable the script.

Description#

Pop-up#

Use M to call up the main Collection Manager pop-up in the 3D Viewport when in Object Mode. It can also be found in the Object ‣ Collection menu.

View Layer
Render

Enable/disable rendering of this view layer with this checkbox.

View Layer

Data-Block Menu of the current view layer.

Expand All Items

Toggle all collections expanded or collapsed. Only enabled when you have subcollections.

Renumber QCD Slots

Shown only if QCD is enabled in the preferences.

  • LMB – Renumber the QCD slots from the root slot (the slot designated 1) down to the bottom, for each depth level (breadth first search).

  • Alt-LMB – Renumber from the first top-level collection in a breadth first search pattern.

  • Ctrl-LMB – Switch the renumber pattern to linear. This pattern will renumber straight down the list regardless of hierarchy.

  • Shift-LMB – Constrain renumbering to the branch under the root slot.

Hint

All options can be combined with each other.

Undo

Undoes the previous action.

Note

Clears any in progress copy or swap actions.

Redo

Redoes the previously undone action.

Specials
Remove Empty Collections

Remove all collections that have no subcollections or objects.

Purge All Collections Without Objects

Remove all collections that have no objects regardless of whether they have subcollections.

Select All Cumulative Objects

Select all objects that are in more than one collection.

Display Options (funnel icon)

Choose which restriction toggles are shown in the interface and whether the restriction toggles are aligned to the right in the tree view.

Scene Collection
Set Active Collection

Sets the active collection to the Scene Collection.

Name

This is static and can’t be edited.

Select All Objects in the Collection (multiple icons)

  • LMB – Select all objects in the collection (deselects all other objects).

  • Shift-LMB – Add/Remove all objects in the collection to/from the selection.

  • Ctrl-LMB – Select all objects in the collection and all of its subcollections (deselects all other objects).

  • Shift-Ctrl-LMB – Add/Remove all objects in the collection and all its subcollections to/from the selection.

Icons and button highlights are used to show the selection state:

  • no icon – No objects are present in this collection to be selected.

  • no highlight – No objects are selected in this collection.

  • Diamond outline – Objects are present in the collection.

  • highlight – One or more objects are selected in this collection.

  • Filled diamond – All objects are selected in this collection.

  • small dot and grayed out – No objects can be selected in this collection (the collection is hidden or marked as not selectable or all objects are marked as not selectable, etc.). Note: The button isn’t disabled to allow selecting subcollections; however, if you LMB click on it it will deselect all objects.

Hint

If you try to select all the objects in the collection but the diamond doesn’t fill, that means you have one or more unselectable objects in the collection.

Send Objects to Collection (multiple icons)

  • LMB – Move selected object(s) to collection.

  • Shift-LMB – Add/Remove selected object(s) to/from collection.

Icons are used to show the object/selection state:

  • Import – No objects are present in this collection.

  • Box outline – Objects are present, but none are selected in this collection.

  • 3 boxes with dashed outline – The collection contains objects that are selected, but does not contain the active object in the selection.

  • Filled box – The collection contains the active object in the selection.

Note

The active object must also be selected to be indicated/moved.

If no objects are selected the button is disabled.

Global Restrictions (checkbox, cursor, eye, screen, camera, holdout, indirect only icons)

See the Outliner page for information about Restrictions.

  • LMB – Enable the restriction for all collections. Click again to restore the previous state.

  • Ctrl-LMB – Copy/paste the restriction state on all collections. Click on an RTO to copy the restriction state, then click on another RTO to paste it.

  • Ctrl-Alt-LMB – Swap the restriction state on all collections with that of another restriction. Click on an RTO to copy the restriction state, then click on another RTO to swap the two.

  • Alt-LMB – Discard the previous state, and anything that has been stored for Copy/Paste or Swap.

Tree View

Shows the collections within the current selected scene.

Disclosure (small triangle icon)

  • LMB – Expand/collapse subcollections.

  • Shift-LMB – Isolate the tree. Collapses everything but the current item, and it’s parents/descendants. Click again to restore the previous state.

  • Ctrl-LMB – Toggle the restrictions of the collection and it’s descendants on/off.

  • Alt-LMB – Discard the previous state.

Remove X

Remove the collection.

Filtering
By Name

A text field to filter collections by name.

Invert <->

Invert filtering (inverts the collections shown in the tree view so that what is shown is hidden and what was hidden is shown).

By Selected (3 boxes with dashed outline icon)

Filter collections by selected objects (show only collections that contain the selected objects).

By QCD Slots (Q key icon)

Filter collections by those designated as QCD slots (show only collections that correspond to a QCD slot). Shown only if QCD is enabled in the preferences.

Hint

All options can be combined with each other.

Add Collection, Add Subcollection

Self-explanatory.

Note

If the tree view is filtered when adding collections, new collections that do not fit the filter rules will be displayed until the filtering changes.

Phantom Mode

All visibility changes made in this mode will be discarded when it’s disabled.

Enabling Phantom Mode saves the current state of the restrictions and allows you to edit them without fear of losing their current state. When finished, disabling Phantom Mode will restore the saved state.

Note: You will be unable to edit anything other than the restrictions while in Phantom Mode.

Apply Phantom Mode (check mark icon)

Applies all changes made to RTOs while in Phantom Mode and exits the mode.

QCD#

The Quick Content Display system provides a way to rapidly interact with collections by allowing you to designate up to 20 collections as QCD slots. You can then interact with these slots by using hotkeys or the widget to view or move objects to them.

3D Viewport Header Widget#

The header widget is composed of the Quick View Toggles button and 20 QCD slots.

Quick View Toggles (eye icon)

  • Create All QCD Slots. (Creates any missing QCD slots so you end up with a full 20)

  • LMB hold down – Opens a menu with all Quick View Toggles.

QCD Slots

20 buttons in two rows in groups of five where the first row starts with slot 1 and the second with slot 11.

The state of each slot is shown with a combination of the following indicators:

  • x – Unassigned slot.

  • non-highlighted – non-visible slot.

  • highlighted – visible slot.

  • no icon – no objects in the slot.

  • horizontal line icon – objects are present in this slot.

  • circle icon – one or more objects in this slot are selected.

  • dot icon – the active object is in this slot.

Assigned Slot Hotkeys:

  • LMB – View single slot excluding all others.

  • Shift-LMB – Add/remove slot to/from view.

  • Ctrl-LMB – Create the slot and move the selected objects to it.

  • Shift-Ctrl-LMB – Create the slot and add the selected objects to it.

Note

The slot number and its associated collection name, as well as all the relevant hotkeys, are shown in the tooltip when hovering over the slot.

Move Widget#

Use V to call up the Move widget in the 3D Viewport when in Object Mode. It can also be found in the Object -> Collection menu.

The Move Widget shares its layout and indicators with the 3D Viewport header widget.

Edit Mode

All Object Mode hotkeys except for Select All QCD Objects and the Disable Objects hotkeys. (Only available if enabled in the preferences.)

  • AccentGrave – Mesh Select Mode menu.

Note

Slots with objects not in Object Mode can not be excluded.

Preferences#

Disable objects instead of hiding

Replaces the object hiding hotkeys with hotkeys to disable objects instead and adds these options to the Object ‣ Show/Hide menu.

Disabling objects prevents them from being shown again when a collection’s exclude checkbox is toggled off and on, and so will preserve the object’s visibility when switching QCD slots.

QCD

Enable the QCD system.

QCD Hotkeys

Enable 3D Viewport hotkeys in Object Mode.

QCD Edit Mode Hotkeys

QCD 3D Viewport Header Widget

Enable the widget containing the QVT menu and a graphical representation of the 20 QCD slots in the right-hand corner of the 3D Viewport header.

Note

Create All QCD Slots and Enable All QCD Slots Isolated (from the QVT menu) currently don’t have hotkeys and are only available through this widget.

QCD Move Widget:
Tool Theme Overrides

Enable overrides in this section to change the color of individual elements in the QCD Move Widget (colors default to the current theme).

Icon Alpha

Opacity of the icons for selected (but not active) objects and unselected objects.

Note

The values for icon alpha are not overrides and always affect the QCD Move Widget.

Known Issues#

  • Linked collections are not supported.

  • Two QCD slots can swap collections if the collections are under the same parent and you rename one collection with the name of the other, then undo the rename and redo the rename.
