exporting animation FBX child objects animation error

Hey, i’m using unity’s mechanim system to animate my boat. However when I export my animations in FBX format and import them to my game, the animations child objects doesn’t move as they should(rotation,position). They work fine in the preview, but once applied to the scene it seems like the grouping of these objects broke.

I cannot attach these child objects to the boat since i need to use them in my game later on to position objects on them.

Is there somekind of a trick i should do before exporting? i’ve tried to collapse trajectories, but even that doesn’t work.

Problem solved, I moved the obejects in unity’s hierarchy to be child objects of certain part of the boat
