Maya Motion Path issue!!

hello folks.

i have a animated low poly guy who makes a walkcycle along a path in maya. i used "attach to motion path" to make my guy walk on a path. everything is perfect so far.

whenever i import my model into unity either in .ma format or .fbx, i could make it to walk the guy on where he is standing but nothing more. it doesnot travel on the path like the way i made it walk in maya. i guess unity doesnot acknowledge the curve or the path.

is there a fix for this, or am i missing something? i tried to use itween but it is not working as smooth as i want it to be...

thank you guys in advance...
