Problem about passing joint's translation to node

[freedom108]

I'm dealing with a strange skinned animation which is making the character jumping, however the root joints has a big translation during the play and return to the original position on replay and go on with the big translation while loop playing.

So, To prevent this kind of problem, I think what I should to is to kill the in-frame translation and pass it to scene node's translation.

Is there any good idea? Thanks.
