That is the system I was referring to. The entire actor body is comprised of a head mesh, a body mesh, hands mesh & feet mesh. All four are put together by the game. The hands and feet are separate from the body so that you can choose to have any combination of clothed or naked. The head is separate so that it can be decapitated. The decapitated gore which is added to hide the internal default gaps where the neck on both head and body meshes meet is assigned to the race record. These decapitated gore parts are hard coded to appear only during decapitation events. After looking, there are already Armor Addon forms set up for that so modified nifs do not need to be created like I originally thought. These AA plus a new AA that uses the actor's standard head mesh combined on a single Armor form could give a "helmet" item that the player can take from the deceased. However, that does not cause the npc body to lose the head visually. Perhaps a new item that is the decapitated neck gore (body side only) that also uses the head body slot could be force equipped and effectively make it appear as if the head has been severed and removed by the player. I'm wondering if I should do a proof of concept plugin. Something that has willing volunteers to be killed and decapitated... I, however, have no desire to make a fully fledged mod out of this. But, if needed, I could do the base concept and ensure it works as I think it would. I volunteer lol
