After reading this thread, I have a general idea of when to merge the hands with the weapon.
However, when it comes down to animations (such as weapon firing, reloading, etc.), how can it be done if the weapon is not merged with the hands? Take a weapon’s firing animation for example. There’s more than just the kickback from the shot, say you want to animate the bolt as well. Or animate the weapon’s charging handle in a reload animation.
I can’t see any method to animate these weapon parts if the hands are not merged with the weapon. Is there a way?
