Guide on adding a new model, animation, and creature to HoMMV

As I understand it, though this isn't certain, you need to do the following: - Create a bone (with any name, even "Petrushka"), and attach a model-mesh to it. Then, there are several options; choose one from the following:
a) Create an additional bone named GLOBAL and link the bone responsible for the model's animation to it.
b) Create a "HELPER" (Dummy or Point) named GLOBAL and link the bone responsible for the model's animation to it.
c) Combine the bone responsible for the model's animation and the model itself into a group named GLOBAL.
The main thing is to avoid having identical names, because this will create a dilemma during export, as to which one will be the main one 🤪
