When I import a character + animations into the UE4, everything works fine, but only the belt of the character isn't imported

Hey ho,

as I said above, when I try to import them into ue4 it works just as usual, but the belt isn’t imported. I use fbx13 and both the character mesh and the rigg have been used in previous animations,where I was able to export completely, without any problems. Btw the exportation source is Maya 14. Does any body have an idea, how to solve this, I’m going crazy because of this…

Thanks in advance for any possible advice.
