Object `row1` not found?

질문 : Deformation order 를 바꾸기 위해 오브젝트에 right click 하고 Inputs > All Inputs 를 실행했더니 이런 에러가 뜨는데 해결 방법은?
답 :

1. Delete all layers you have in the scene.
2. Save your scene without layers.
3. Restart Maya.
4. “Import” your saved scene into the emty one !! don’t open it - just import!!
5. Save new scene.

MEL 을 이용한 방법 (더 간단하다):
