Hi! I tried to use unreal engine's character to edit skeleton with Houdini, but after the ROP FBX Character output the character's skeleton hierarchy have change. I used maya and find out it turn the default group to a bone which cause this issue. I know in this workflow use curve but the UE & Maya use the joint. Maybe it convert the empty to a joint. Do anyone have any idea?

I found the solution. Just uncheck the "Export User_Defined Attributes"checkbox and it preserve the skeleton hirerachy.

I shoud check rig tree or path attribute before export, that's may the proper way to solve this issue.
