Did you ever look at HAnimJoint center output from blender during
WinterAndSpring project?

Blender bones have joint centers for their heads and tails.

This seems to be a way forward, and hopefully we’ll be able to attach
empties to bones and armature:

https://blender.stackexchange.com/questions/308924/attach-axe-to-bone-in-blender-python-api


Summary:


mesh_obj.parent = empty_obj

empty_obj.parent = armature_obj
empty_obj.parent_bone = bone_name
empty_obj.parent_type = 'BONE'



If this works, we’ll have to tackle animation.

OK?

Nothing renders because Jin 20 has no mesh or animation.

The hierarchy is great, though?

Now you know why I was trying to combine HAnim exports with glTF.
Ultimately, I had to export my own weights, and shifted to pure X3D exports.
