by rotation you probably touched bone rotation as well
The orientation of the bones shouldn't matter.
About outside bones, not sure, they might be unused or used to attach objects to the model.
idk, maybe someone from Harry Potter?
Actually, after I finished homework, I saw that video first and answered, before going to the other server.
Thought it was Harry or some comerade
yeah, the cape would be probably be difficult to animate
It would be easier to remove the cape or find a model without.
Also after I do automatic weights, I remove the weights of the head from all bones, and only apply the head on the head bone
so the head doesn't get affected by bones for Asterix's eyes, nose, mouth, helmets that don't apply to the imported model
Not including a changelog @adrientd

I didn't have time to do one.
Also no need to do one as long it is not public.
