Copy and pasted prefab not being rendered.

I copy-and-pasted a part of prefab to another prefab, so that i can handle them as a single prefab.
But pasted part of prefab is not being rendered, when the original one is.
is there any problem with its renderer component??
character_01 is the original and character_02 is moved from another prefab.


see Skinned Mesh Renderer component - Unity 手册
you have to copy with body
