What does this file do?

Well, it gets rid of mannequins of course, how?

Umm, it deletes them.

I have a mod with custom Mannequins, I like the mod, but I don't want the Mannequins,
will this help?

Provided the mod uses the base assets from the vanilla game, yes it will if you place
this after that file in your load order.

Removes thefollowing:

PlayerHouseMannequin (This is the Mannequin it's self)

MannequinStay (Thisis the script used to try and make it stay still)

MannequinArmorWeaponsMESSAGE (A message that would appear when trying to equip items to the
Mannequin)

MannequinActivateTrig (The mannequin trigger which activates the Mannequin)

MannequinActivateMESSAGE (The accompanying trigger message)

There are stillMannequin Bases?

A lot of the Mannequin bases are not really specific Mannequin objects, in most
cases they are things like round tables where only the top shows
above the ground, removing them would remove all round tables.

The only other resource used by mannequins which I have not removed is the x-marker,
which is a direction control marker, again this is not a specific
Mannequin resource, it is used to control the direction that npc's,
static objects and effects are facing, removing this would be a
little chaotic.
