3SAX 中添加部件时 Part ID 是什么意思？

What Part ID means

Part ID is the unique name of one part inside a Material Group (SG). Parent ID points to another Part ID, so the tree is built by matching the two.

Part ID 是材质组（SG）中某个部件的唯一名称。Parent ID 填写另一个 Part ID，父子树靠两者匹配建立。

1. Open the SG Material Group panel.

1. 打开 SG 材质组面板。

2. Upload your PNG parts.

2. 上传 PNG 部件。

3. For each part, type a unique Part ID (green hint = valid, red = error with a fix example).

3. 为每个部件填写唯一 Part ID（绿色提示为有效，红色为错误并给出修正示例）。

4. Set Parent ID to the Part ID of its parent; leave empty for a root part.

4. 将 Parent ID 设为父部件的 Part ID；根部件留空。

5. Set baseX / baseY, Anchor X/Y, Scale, Layer, Z-perspective.

5. 设置 baseX / baseY、Anchor X/Y、Scale、Layer、Z 透视。

6. Assign a category (join) and numbered states (frames).

6. 指定类别（join）与编号状态（帧）。

7. Check the tree in CANVAS.

7. 在 CANVAS 中检查树结构。

8. Reference the same Part ID as target part in AG action units.

8. 在 AG 动作单元中把同一 Part ID 作为目标部件引用。

CAN: build parent-child trees, reuse Part IDs as action targets, bind parts to BONE joints, swap parts in AG.
CANNOT: duplicate a Part ID inside one group, use it as a free-text label, or expect Parent ID to accept a part name that does not exist.
Wrong Part ID or Parent ID: validation turns red, the tree breaks, and dependent actions or the render fail.
