How do I delete a part from a material group?

Delete a part by removing it in the SG Material Group panel, then clearing any Parent ID or action references that point to it.

1. Open the SG Material Group panel in the studio editor.

2. Find the part in the parent-child tree by its Part ID.

3. Check its children: any part whose Parent ID equals this Part ID must be reparented first.

4. Remove the part from the group.

5. Open the AG Action panel and check action units that use this part as their target join.

6. Retarget or remove those action units so no seq points to a missing part.

7. Watch the validation hints: green means valid, red shows an error with a fix example.

8. Save the project and run whole-project validation.

9. Fix every item in the clickable error list.

10. Open CANVAS to confirm the character still renders correctly.

• You CAN delete a part and reassign its children to another parent.
• You CAN retarget action units to a remaining part.
• You CANNOT delete a part that still has children or live action references.
• If you do, the parent-child tree breaks, parts fly apart on canvas, and render fails with validation errors; the codec rejects the code.
