In 3SAX V3, overlapping actions on the same frames are not blocked—the Action Group stacks them, and the later/higher action unit applies its values over the earlier one, so the scene plays the combined result. Video only: the tool warns you via input validation but does not auto-merge into one clean unit.
在 3SAX V3 中，同一帧上重叠的动作不会被阻止——动作组会将它们叠加，后加入或层级更高的动作单元会覆盖先前单元的数值，场景播放组合结果。仅限视频：工具会通过输入校验提示你，但不会自动合并为一个干净单元。
1. Open the AG (Action) panel and bind the target Material Group.
1. 打开 AG（动作）面板，绑定目标素材组。
2. Add action units; set each unit's target part (join) and seq frame ranges, e.g. 01:0-5 and 01:3-8 to overlap.
2. 添加动作单元；为每个单元设置目标部件（join）和 seq 帧范围，例如 01:0-5 与 01:3-8 形成重叠。
3. Use auto-suggest sequence to generate a seq matching the part's available states, then adjust ranges.
3. 使用自动建议序列生成匹配部件可用状态的 seq，再调整范围。
4. Add relative rotation, scale, X/Y offsets, swap part, or trigger event per unit.
4. 为每个单元添加相对旋转、缩放、X/Y 偏移、替换部件或触发事件。
5. Check the red/green hints beside each field; fix any red before continuing.
5. 查看每个字段旁的红/绿提示；先修正红色项再继续。
6. Open CANVAS to preview the overlap result; drag to fine-tune dx/dy, edit rot/scale—changes sync back to codes.
6. 打开 CANVAS 预览重叠结果；拖动微调 dx/dy，编辑 rot/scale——改动会同步回代码。
7. If it looks wrong, split the frames or shorten one unit's seq range.
7. 若效果不对，拆分帧或缩短某个单元的 seq 范围。
8. Run whole-project validation and fix the clickable error list before RENDER.
8. RENDER 前运行整项目校验，修正可点击的错误列表。
Try it in the 3SAX V3 creator tool and see the overlap play out.
