Problem to import animation in unity

Hi,i did a weapon with arms in blender(with their shooting animation):

I export it to fbx,and when i import to unity the arms deform when play the shooting animation:

I think that is the arms armature problem but i tried a lot of things,in fact,i have another question with the same problem.I hope that you can resolve this please!(and sorry for my bad english)

Try to apply the scale of the object. :slight_smile:

nobody can resolve this? :frowning:
