It looks like this :
scene = scene as Spatial
for item in scene.get_child(0).get_child(0).get_children():
item.name = item.get_children.name
It results in error that items children don't exist, are null, empty, the same goes for child(0). Scene structure is simple - root/armature/skeleton/10 bone attachments/ 10 meshes. Only meshes are not recognized by script. I tried renaming items and bone attachments were renamed, so I got references correctly. Opening glb scene without import script shows that meshes are children of bone attachments.
Anybody understands this ? Please try to recreate it and help me with this
EDIT : SOLVED - I had one bone attachment without any mesh, sorry
