[4.14] 3DS FBX export: import mesh + bones + fbx , TurboSmooth lost in UE4

Hi there,

I have a model in 3DS Max 2017 with subdivision surfaces (TurboSmooth). When I export the FBX and import the file in ue4[UE4.14], The TurboSmooth was gone.
These are the 3DS export settings I use:

After the import in UE4, the mesh looks like this :

What could be the problem here? Did I something wrong?
