Beginner question: pose editor - rotation

I works now. I switched from cylinder to extrusion + path. So no need for rotation :slightly_smiling_face: (https://playground.babylonjs.com//#CN4KJL#86 )

But I have another beginner question now :slightly_smiling_face:
This is same code but instead of using standard Babylon-dummy file I am using a gdb file:

I can see the object and skeleton but my own objects for bones and joints are gone.
UPDATE: variation using translation nodes: https://playground.babylonjs.com//#CN4KJL#92
using .setParent - but also does not work

Any idea how to fix this?

Thank you!
