如何让部件消失并重新出现？

Use an Action Group (AG) bound to the part's Material Group (SG), and drive its visibility with scale or swap-part units across numbered states.

用绑定该部件材质组（SG）的动作组（AG），通过缩放或替换部件单元在各编号状态间控制显隐。

1. Open SG and confirm the target part has a Part ID and at least two numbered states (visible / hidden).

1. 打开SG，确认目标部件有Part ID，且至少有两个编号状态（显示/隐藏）。

2. Open AG, bind the Material Group, and add an action unit with the target part as join.

2. 打开AG，绑定材质组，添加目标部件为join的动作单元。

3. Set seq ranges, e.g. 01:0-5 to hide and 01:6-12 to show.

3. 设置seq区间，如01:0-5隐藏、01:6-12显示。

4. For a clean disappear, set scale to 0 or use swap part to a blank part. Reverse it to reappear.

4. 消失用缩放设为0，或用swap part换成空白部件；反向操作即重现。

5. Use auto-suggest sequence to generate a seq matching the part's available states.

5. 用自动推荐序列生成匹配该部件可用状态的seq。

6. Check the result in CANVAS; drag to fine-tune dx/dy, edit rot/scale if needed.

6. 在CANVAS预览；拖动微调dx/dy，必要时改rot/scale。

7. Place the action on the role track in AC and render to MP4.

7. 在AC中把动作放到角色轨道，渲染MP4。

Cannot:

不能做：

Hide a part with no AG binding or missing Part ID (validation shows red and render fails).
Reference a state the part does not have (code rejected).
Rely on camera zoom to hide a part (it only crops the view).

Open the 3SAX V3 creator tool and try an AG hide/show unit now.

现在打开3SAX V3创作工具，试做一个AG显隐单元。
