Bone Collections

Note

Bone Collections were introduced in Blender 4.0 as replacement of Armature Layers and Bone Groups. Bone colors are now managed directly on the bone.

Moving Bones between Collections

Blender should be in Edit Mode or Pose Mode to move bones between collections. Note that as with objects, bones can be assigned to in several collections at once.

Move to Bone Collection

Shows a list of the Armature’s editable bone collections. Choosing a bone collection unassign the selected bones from all other bone collections, then assigns them to the chosen one.

Available as Pose ‣ Move to Collection (Pose Mode) Armature ‣ Move to Collection (Edit Mode), and M (either mode).

Bone Collections

Shows a list of the Armature’s editable bone collections. The collections that the active bone is assigned to are prefixed with a -, and choosing those will unassign all selected bones from that collection. Similarly, choosing a bone collection prefixed with a + will assign all selected bones to that collection.

Available as Pose ‣ Bone Collections (Pose Mode) Armature ‣ Bone Collections (Edit Mode), and Shift-M (either mode).

Note

The above operators will only show the editable bone collections. When the Armature is linked, its bone collections will be read-only. New bone collections can still be added via library overrides; only those will be editable.

See Library Overrides of Bone Collections.

Custom Properties

Create and manage your own properties to store data in the Bone Collection’s data-block. See the Custom Properties page for more information.
