Simple animation of a static shotgun

Hey community,

for now I’m ~6 hours working on this problem. I started working with Blender, because I like it even more then 3DS Max for modeling.
My model has multiple objects - chasis, handle and so on.

I animated the “pumpaction” and the shell output in combination with a bone (ue4 thing).
When I export this animated model UE4 only shows the to the bone connected objects. :confused:

May some of you guys can help me here.

Cheers

A screenshot of the hierarchy would be helpful. I believe you’d want to have everything parented / skinned somewhere underneath a single root bone.
