Bone Setup and animation

Hi guys i am new to Unity3D.I have issue with importing model with animation.Model is imported perfectly.But Animation is not imported.I am using IK animation with controls while exporting to .ma file format from Maya.Is it any particular rules for creating bone setup and doing animations.Because this bone setup and animations are created for other game engines.Please help me guys to solve this issue.

Thanks in advance

Have you tried exporting the model in FBX format from Maya?

yes,But i got the same result
Any other suggestion

Is your animation baked down to keys?

Quick test, delete all your controllers and IK handles from the scene and see if the animation plays. If it doesn’t you need to bake the animation down to keys.

Edit → Keys → Bake Simulation[option box]

FK Animations are importing nicely but I have a problem in importing IK Animations(IK controls are animating but Mesh is not animating)
I have both IK and FK Animations.(I tried FK separetely its working nicely).
