What is the best way to implement a 3D model change?

Question

3D

There is a 3D model of a character, there is a 3D model of an axe.
How to do it better?
- Add the ax as a separate object and suffer with binding it to the character
Or
- Add it to the character model (that is, add the coordinates programmatically)

Answer 1

That's right - we add the ax as a separate object and torment... rather than, wait, just make it a child of the bone that is the character's hand, and the ax will move with that bone.

Answer 2

If you have a weapon change, then it seems to me more logical to tie it to the character. And if the ax, as it was, and will always be, then sew it into the model.
