,In unity, maya animation(baked ik spline) file is shaking

Hi, guys.

I have a big problem here. Please help me!!! I took 3days to fix t$$anonymous$$s problem, but I couldn't.

I used IK animation tool in Maya to make snakish animations ...

I exported those snakish animated files from Maya, and put them into Unity engine scene. I clicked the play button in Unity engine to see how animations work. some of animated files worked fine, but some of them were shaking badly in the scene. I don't know why...

I adjusted the settings in the Unity engine to stop shaking, like, turned off the " anim.compression" but it didn't work.

(to add some information, when I export animated objects from Maya, I edit>keys>baked smulation them. because I used ik spline animation. ...)

here is the picture of it. guys please help me!!
