Can I upload a JPEG instead of PNG for a part?

3SAX V3 素材组能否用 JPEG 代替 PNG？

Last updated: 2026-10-21

No. The SG Material Group panel accepts PNG parts only. Use a JPEG only as a reference, then convert it to PNG before uploading.

不行。SG 素材组面板只接受 PNG 部件。JPEG 只能作为参考，上传前请先转成 PNG。

How to do it in 3SAX V3

1. Convert your JPEG part to PNG (keep transparency if needed).

1. 把 JPEG 部件转成 PNG（需要透明就保留透明）。

2. Open the SG Material Group panel and upload the PNG part.

2. 打开 SG 素材组面板，上传 PNG 部件。

3. Set Part ID, Parent ID, baseX/baseY, Anchor X/Y, Scale, Layer, Z-perspective.

3. 设置 Part ID、Parent ID、baseX/baseY、Anchor X/Y、Scale、Layer、Z-perspective。

4. Assign the part category (join) and numbered states (frames).

4. 指定部件分类（join）和编号状态（帧）。

5. Build the parent-child tree, then check the green input hints beside each field.

5. 建立父子树，检查每个输入框旁的绿色提示。

6. Link the group in AG, preview in CANVAS, validate the project, then render MP4.

6. 在 AG 中绑定该组，在 CANVAS 预览，整项目校验后渲染 MP4。

CAN: upload PNG parts, set all part parameters, build parent-child trees, preview and render.
CANNOT: upload a JPEG as a part.
If you try a JPEG, the upload is rejected by input validation (red hint); the part is not added and the tree stays incomplete, so the animation or render fails.

Try it now in the 3SAX V3 creator tool.
