Non rigid animation to unity

I've got an animation in maya and I want to export it to unity. There are no bones, no deformer or anything else. Just a sipmle rotation and translation animation. The FBX is fine (I've cehcked it, the aniamtion is there). But in unity, nothing will move. Unity detects the framerange, so i tink there is the problem with unity. Can anybody help? Thanks Sebastian
