incorrect Position between two animations

Hello, I have a problem.

I have two animation which I got from mixamo, idle and walk. I realize that idle and walk animation doesn't placed correctly, the foot is lower than idle so I modify the walk animation to make it equal on height by using blender. But when I export again it's totally wrong, it's like the floor isn't equals to floor on idle animation. It's hard to me to explain but I hope you can understand it through the picture that I specified. Here is:


idle


walk

 

I found solution, I must config import settings to humanoid and make sure every bones are defined in unity by using enfore t-pose. Do the same to every animation and model and the last thing make sure to set root transform Y in foot and then voila! position offset is always on middle of object whatever the original position is in the animation file.
