MotionBuilder to Unity. What export for animations only

Hello,


I have a scene in MotionBuilder and in it a character with control rig and a take applied to it. I would like to export only the animation data to use with Mecanim. When I save as .fbx what should I check as minimum so that the file has only animation data and what's necessary to import it into Unity?

I did try several combinations but with no success.

Thanks!
