How can i fix this Fbx. bug?

I imported an Fbx character model that i had created on fuse but, when I opened it on UE4, appeared some strange spikes on the right hand, and the model wasn’t well enought. Please answer me, I need your help because it is for an school project.

Hi Jabalera,

Those spikes are caused by the skin weights not being properly painted onto the character in the program it was created in.
