Steps to reproduce :

- import the project attached
- click on "Elum_idle" animation and notice that the position of the root node is between the feet
- open the max file in the project folder and notice that the root position is just behind the character's feet

Explanation :
This is normal because you are using a humanoid rig which retarget the motion and compute a root motion from the retargeted data.

If you want an exact match for your root position you will need to switch the rig to generic in model importer.
