Model prep from Autodesk Alias to Unreal through Datasmith not working correctly

Hi Everyone,

So i am new to unreal engine, and attempting to learn, but i feel like a bit of an idiot because i cant seem to load the the file correctly via Datasmith. Whats loaded are multiple surfaces which arent grouped and surfaces suddenly floating. Its not like the wire file at all. I was wondering if someone could just enlighten my on how or what could cause this issue.

Cheers Guys.
