Unable to duplicate walk animation

I was trying to duplicate olofmoleman's Nazgul Model's walk animation with the animation transferer. When I do this and look at the new animation in wc3veiwer, only the upper body moves, not the horse. Seeing as the model is based off the Death Knight, I tried to transfer the Death Knight's walk animation to the Nazgul, and get the same effect. Then I tried to duplicate the walk animation from Blizzard's Death Knight to a copy of the same mdl, I get the same thing. Anyone know how I can get the walk animation to duplicate without only one potion of the model moving?

Hmm hmm.

Sounds like some of the model is on bones and not helpers; the animation transferer only works on helpers. Which means you'll need to manually do the rest, if this is true.

Make sure bones have same name?

What exactly do you mean? Look at Black_Stan's models, they operate on bones solely and the animations are completely transferable with helper-animated units, and I've transferred wc3 animations onto them as well. I haven't really explored it further, but I'm beginning to think it's a common misconception. Maybe it simply looks for the appropriate names of the bones/helpers?

Considering it's duplicating an animation on the same model, that seems the only explanation; bone/helper names will obviously be the same.
