Import problem... geometry on a certain material not visible for skeletal mesh

So i have my character bound to a skeleton and i noticed the eyes are not importing. The material and the joints are there for them, but the eyes geometry are not there… why would this be? Its a pretty standard smooth bind with selected joints…

As a static mesh this imported fine.

Even when i create 1 single joint nad bind all geometry to that… the eyes are not rendered… when in engine… makes no sense… yet on static mesh its fine…

I have literally tried exporting the eyes alone to obj… then importing that back in to bind to the skeleton… and that didnt work either…
