For this video I'll be showing you how to make a unique weapon using the Fallout 4 Creation Kit.
[UPDATE]
So to sort of explain things a little better, the quest is so that there is only one of said weapon that you are going to be putting into the game since instead of it being a modified weapon it is simply it's own thing. With the dummy marker since it's a dummy it won't actually appear in the world and instead create a reference that we could use for more than just the unique weapon. This dummy isn't needed when using a container since the container becomes the reference. I will make another video involving the leveled weapons as well as modified weapons in which the stats can go over to the unique variant. Hope this clears a couple things up.
