Attach, position, and mirror costume parts

Understand attachments and attachment points, adjust part properties, and use Shift+M to toggle linked mirrors with undo and redo.

An attachment is a costume part placed on your avatar from a workspace. The workspace holds the model and its patterns. The attachment gives that model a position, rotation, and scale on the avatar so you can check its fit.

An attachment point anchors the part to a body region, such as the head, shoulder, forearm, or calf. The part follows that point as you pose the avatar. You can adjust its placement after attaching it.

Attach a workspace to your avatar

1. Select a workspace

   Import a model, then select it in the Workspaces Panel.

2. Choose an attachment point

   Click Attach. A ghosted preview of the part follows your pointer. Click the attachment point on the avatar where the part belongs.

3. Position and fit the part

   Select the attached part in the Costume viewport or Attachment Tree. Use Translate (T), Rotate (R), and Scale (S) to fit it to the avatar.

   Use the Transform Panel for exact values. Inspect the fit from several angles before moving on to the next part. Enable Fit Checker to see a heatmap of clearance around the avatar.

Start in the avatar’s neutral T-Pose when fitting parts. After positioning them, use posing to check how the costume moves with the body.

Select and manage attachments

The Attachment Tree lists your attached parts under their attachment points. Click a part’s name to select it. Use its Visible checkbox to show or hide it.

If you attached a part to the wrong body region, right-click the selected part in the Attachment Tree, choose Move Part, and select another attachment point. Use Delete Part to remove the attachment from the avatar.

Deleting an attachment leaves its source workspace available. Deleting the workspace also removes its connected attachments.

Attachment properties

Select an attachment to inspect its Property Grid. Use the Transform Panel for position, rotation, and scale.

Property	What it controls
Name	The label shown for the part in the Attachment Tree.
Visible	Whether the part is displayed. Hide it temporarily to inspect other parts or the avatar beneath it.
Frozen	Whether the part is excluded from viewport selection. Freeze a fitted part to avoid selecting it while working nearby.
Color	The part’s display color.
Opacity	How transparent the part appears. Lower it to see the avatar through the part while fitting.
DrawTextures	Whether the part displays its textures. Turn it off to inspect the shape without texture detail.
Wireframe	Whether the mesh displays as wireframe. You can also toggle this with W in the Costume viewport.
Thickness	The source workspace’s default material thickness. Attachments from that workspace use the same workspace setting.
Mirror	Whether a linked mirrored copy is attached on the other side of the avatar.
Position, rotation, and scale	Where the part sits, which way it faces, and its size. Adjust these in the Transform Panel or with the viewport tools.

Mirror an attached part

Mirroring is useful for paired costume pieces such as shoulder pads, bracers, and greaves. For example, fit a bracer to the left forearm, then enable Mirror to place its reflected copy on the right forearm.

Armorsmith uses the opposite attachment point when one is available. For an attachment point without an opposite partner, the reflected copy uses the same attachment point.

1. Select the original attachment

   Select the part in the Costume viewport or Attachment Tree.

2. Toggle the mirror

   Focus the Costume viewport and press Shift+M. You can also change the attachment’s Mirror property in the Property Grid.

   Press Shift+M again to turn mirroring off and remove the mirrored copy from the avatar. The original remains attached.

3. Adjust the pair

   Move, rotate, or scale the original attachment to update its linked mirror. Selecting the mirrored copy selects the original so you can adjust the pair together.

For different shapes or independent placement on each side, attach separate parts instead of using a linked mirror.

Mirror several selected parts

Shift+M toggles the Mirror setting of each selected attachment. A part with mirroring off turns it on; a part with mirroring on turns it off. A selection with mixed settings keeps that per-part toggle behavior.

The shortcut acts on individual attached parts. Select the parts themselves when working with a group.

Undo and redo mirroring

Press Ctrl+Z to undo a Shift+M action. Every affected attachment returns to its previous mirror setting in one step, even when you selected several parts. Press Ctrl+Y to redo that same action.

Changing your selection afterward does not change which attachments that undo or redo affects.

Shift+M and the single-step undo/redo behavior are available in builds that include the updated mirror command. Earlier builds use C for the mirror shortcut. M remains the shortcut for Measure.
