I already had that bone for making "stand moving" animations, like "roll" or "enter a door". But in this particular case, I need that the root bone moves with the character. I move the root bone in a "jumps animations" is easy to me to watch how the animations is looking. Then, when I export the character animations, he is always in the same position and the programmer moves the character.
Well, in this case i will make the animation using the "stand moving bone" and then I will delete the keys of this bone.
Thanks for a quick answer!
