Change units Height with Animations (Like naga when they swim)

[Nosticus]

Hello, I used to know how to do this, but I forgot and now can't find the Article I once read to figure this out, but how do you make a unit change its height when it plays a specific animation like swim, the model is above ground in the model editor, but then when the swim animation is used the model moves under where the model would be if it was playing a normal non-swim animation, how does one do this again?

Figured it out, you gotta modify bones in Node manager, set em to a negative value when playing specific animations xD
