[Solved]Weapon on NPCs - Variables?

I m trying to do something weird, but I use NPC inventories and equipment to give weapons to friendly npcs and equip with them, I use 2 camera setup on my First Person controller, so I have other layers for weapons/hands etc. What I need to do is when I give a weapon to an NPC or equip them with one, to be able to change the layer of the prefab, is that possible through ork? Any other way you can think that I can do it?
