When playing FBX animations, the coordinates of some models deviate from the grid

While implementing the HY-Motion plugin https://github.com/jtydhr88/ComfyUI-HY-Motion1, I found that when playing FBX animations, the Z-axis of some models is positioned above the grid floor. Although this shouldn't affect usage, it results in a poor experience.
