Common mistakes when setting parent IDs in a material group?

A wrong Parent ID breaks the parent-child tree: parts detach, move alone, or the code is rejected at validation.

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

2. Give every part a unique Part ID before linking anything.

3. Leave Parent ID empty only for root parts — one root per chain.

4. Set Parent ID to an existing Part ID; never to itself, never to a part that comes later in the chain.

5. Avoid circular links (A parent of B, B parent of A) — this fails validation.

6. Set baseX/baseY, Anchor X/Y, Scale, Layer and Z-perspective for each part.

7. Check the green/red hint beside each field; fix red ones using the shown example.

8. Before render, run whole-project validation and click through the error list.

• CAN: build multi-level parent-child trees, bind parts to BONE joints so attached parts move together.
• CANNOT: use a duplicate Part ID, point Parent ID at a missing part, or create loops.
• Wrong Parent ID: parts fly apart in CANVAS preview, actions hit the wrong target, render fails.
