Slots, Image Binding, and Draw Order

Bone
└─ Slot (attachment container and draw-order unit)
   └─ Image attachment (references an image resource)

• The Images panel is a resource library. An asset there is not necessarily part of the character.
• A slot attaches its attachments to a bone and participates in draw order.
• One slot can contain multiple attachment candidates, but only the active one is displayed.

1. 1

   Select the correct resource

   Expand default in Images and locate the slice. Compare its thumbnail and name to avoid mixing up the two sides.

2. 2

   Drag to a bone or existing slot

   Drag the image resource onto the intended bone or slot. If the bone has no slot yet, the editor asks you to confirm a new slot name.

   Expected resultThe slot and image attachment appear in the hierarchy and the image is visible on the canvas.

3. 3

   Check following and active state

   Move the bone slightly to confirm the image follows, then undo. If the slot has several attachments, verify which candidate is active.

   Expected resultThe image follows the bone and displays the intended attachment.

1. 1

   Adjust draw order

   Expand Draw Order on the right and drag the target slot to the appropriate position. This changes image ordering, not bone parenting.

   Expected resultCanvas occlusion updates immediately while the skeleton stays unchanged.

2. 2

   Distinguish three kinds of visibility

   Check node visibility, the canvas image display toggle, and the active attachment in the slot. Press 1 to toggle images on the main canvas.

   Expected resultYou can tell whether an invisible image is caused by a hidden node, a canvas toggle, or attachment selection.

3. 3

   Check occlusion during playback

   If the animation contains draw-order keys, inspect the order at different frames rather than fixing only frame 0.

   Expected resultKey poses and loop seams have no obvious occlusion errors.
