Import C3D FBX losing object Subdivision

Asset & Content Management
1

I created a skeleton rig character model with subdivision in cheetah3d,

export it as .fbx
also tried .jas

When I open it in unity iphone, the subdivision LOST!

I tried both fbx and jas format.

How should I fix it?

I found that if there is no skeleton in the model, the subdivision does not lose.

However, if there is no skeleton, how can I make the animation?

Anyone could help?
