Do uploaded parts need transparent backgrounds?

上传的部件需要透明背景吗？

Not required, but strongly recommended. SG parts are PNG layers stacked by Layer/Z-perspective; transparent PNGs keep edges clean while opaque backgrounds block parts behind them.

不是必须，但强烈建议。SG 部件是按 Layer/Z 透视叠放的 PNG 图层；透明 PNG 边缘干净，不透明背景会遮住后面的部件。

How to do it in 3SAX V3

在 3SAX V3 中怎么做

1. Open the SG Material Group panel and upload your PNG parts.

1. 打开 SG 材质组面板，上传 PNG 部件。

2. For each part, set Part ID, Parent ID (leave empty for root), baseX/baseY, Anchor X/Y, Scale, Layer and Z-perspective.

2. 为每个部件设置 Part ID、Parent ID（根部件留空）、baseX/baseY、Anchor X/Y、Scale、Layer 和 Z 透视。

3. Assign a category (join) and numbered states (frames) to each part so AG actions can target them.

3. 给每个部件指定类别（join）和编号状态（帧），供 AG 动作调用。

4. Use CANVAS to preview the stacked result; drag to fine-tune dx/dy and check edges.

4. 用 CANVAS 预览叠放效果，拖动微调 dx/dy 并检查边缘。

5. If edges look wrong, re-upload the part as a transparent PNG and re-link its Parent ID.

5. 边缘不对就换成透明 PNG 重新上传，并重新设置 Parent ID。

What you CAN and CANNOT do

能做与不能做

CAN: use transparent PNGs for clean overlapping parts and parent-child trees.
CAN: preview stacking instantly in CANVAS before arranging actions.
CANNOT: remove backgrounds inside the tool — prepare transparency before upload.
CANNOT: expect opaque parts to blend; they cover parts behind them, and CANVAS will show the block.

能做：用透明 PNG 实现干净的部件叠放和父子树。
能做：在 CANVAS 中即时预览叠放效果。
不能做：工具内不提供抠图，上传前自行处理透明。
不能做：不透明部件无法融合，会盖住后方部件，CANVAS 中可见遮挡。

Try the 3SAX V3 creator tool and upload a transparent part set to see the difference.
