# Vertex Groups Panel¶

Reference

Mode

All Modes

Panel

Object Data tab ‣ Vertex Groups

The Vertex Group panel.

Vertex groups are maintained within the Object Data Properties Editor, and there in the Vertex Groups panel.

Active Vertex Group
Lock

Locks the group from being editable. You can only rename or delete the group.

Add +

Create an empty vertex group.

Remove -

Deletes the active vertex group.

Specials
Sort by Name

Sorts vertex groups alphabetically.

Sort by Bone Hierarchy

(Todo)

Copy Vertex Group

Add a copy of the active vertex group as a new group. The new group will be named like the original group with "_copy" appended at the end of its name. And it will contain associations to exactly the same vertices with the exact same weights as in the source vertex group.

Copy vertex groups of this mesh to all linked objects which use the same mesh data (all users of the data).

Copy Vertex Group to Selected

Copy all vertex groups to other selected objects provided they have matching indices (typically this is true for copies of the mesh which are only deformed and not otherwise edited).

Mirror Vertex Group

Mirrors weights and/or flips group names. See Mirror Vertex Group for more information.

Mirror Vertex Group (Topology)

Performs the Mirror Vertex Group with the Topology Mirror option enabled.

Remove from All Groups

Unassigns the selected vertices from all (even locked) groups. After this operation has been performed, the vertices will no longer be contained in any vertex group. (Not available for locked groups.)

Clear Active Group

Remove all assigned vertices from the active group. The group is made empty. Note that the vertices may still be assigned to other vertex groups of the object. (Not available for locked groups.)

Delete All Unlocked Groups

Remove all vertex groups from the object that are not locked.

Delete All Groups

Remove all vertex groups from the object.

Lock All

Lock all groups.

Unlock All

Unlock all groups.

Lock Invert All

Invert group locks.

## Editing Vertex Groups¶

Reference

Mode

All Modes

Panel

Object Data tab ‣ Vertex Groups

Mesh ‣ Vertex ‣ Vertex Groups

Hotkey

Ctrl-G

Vertex Group panel in Edit or Weight Paint Mode.

When you switch either to Edit Mode or to Weight Paint Mode vertex weights can be edited. The same operations are available in the 3D Views Mesh ‣ Vertices ‣ Vertex Groups menu or Ctrl-G.

Assign

To assign the selected vertices to the active group with the weight as defined in the Weight (see below).

Remove

To remove the selected vertices from the active group (and thus also delete their weight values).

Select

To select all vertices contained in the group.

Deselect

To deselect all vertices contained in the group.

Weight

The weight value that gets assigned to the selected vertices.

Set Active Group

Lets you select the group that will become the active one (menu only).

ヒント

Multiple objects sharing the same mesh data have the peculiar property that the group names are stored on the object, but the weights in the mesh. This allows you to name groups differently on each object, but take care because removing a vertex group will remove the group from all objects sharing this mesh.
