What?
They have standart bone rigs.
Quote: " however when you export the animation, it exports it as an animated mesh, not a bone controlled hand."
I never used blender and I am aware that boneless animated meshes exist, I have never seen one though and I can guarantee you that the stock weapons all have bones.

I see! So its not for an FPSC project then?
Well, you can use the scifi/glaive handset as it has both hands already fully rigged. Just remove bones and the mesh of the glaive and you can animate it.
This implies that you know how to animate the standart Bone/joint rigs. I am aware that software like maya and max have different, more modern bonesystems that make animating easier and more approachable...if this is what you are after, I cant help you.
