every time i try to port my skeletal mesh to it. I've messed with the smoothing groups, the UVs, and some of the import options in Unreal to no avail. Any ideas?
Blender Export Settings:

Unreal Import Settings:
it appears that unreal engine crashes when the blender animation FBX is without a material.
This means if you add a texture or material to your object it will work.
