Best approach for importing a custom character ( skeletal mesh ) into UE4 ?

Hello.
I need to ask you something. I am at the point of importing my skeletal mesh character into Unreal Engine. I want to ask you what’s the best approach ( method ) for importing the custom character ?

I have rigged my character and every part of the equipment, that is meant to be imported ( he’s going to use modular equipment system: top, trousers, boots, gloves, helmet ).

So atm I have:

  • rigged nude ( only underwear ) body skeletal mesh with underwear ( own material ) with eyes ( own material ) with hair ( own material )
  • eyelashes skeletal mesh ( own material ) , so I can add the blink animation to the eyelashes
  • armor parts ( elements as boots, top, trousers etc. )

I am going to use a blend spaces as the facial animation method, do I need any special kind of preparation to my mesh in order to make face animations look natural ? I mean maybe the tooth have to be separate skeletal mesh component etc. ?

What do you think ?
