Help rigging view models for Blender animations

So I have some viewmodel rigs. I want to animate the rigs in blender. But whenever I try to Build Rig using this plugin, the bones are never made. I am not a Blender guy so I’m totally lost.

BerettaViewmodel.rbxm (162.4 KB)
GalilViewmodel.rbxm (53.4 KB)

Please help!!

Does anyone know what is wrong? I have been trying since last week and can’t solve the problem. Or even figure out the error…
