Can't import cloth

Hi everyone. I made a model with maya. and i added some cloth to it using apex. Here is my problem.

  1. In maya apex cloth doesn’t collide with kynmatic ragdoll.
  2. I skinned and give new lambert material to cloth from maya. But when i imported it to ue4 cloth doesn’t importing as model. I mean i exported fbx and apx. But there is no polygon for cloth to make it cloth.

I got pictures.
This is maya:
