Editing Adding Sellable Items To Merchant NPC

__NOTOC__
First, uncheck the "auto calc stats" if the NPC is not a merchant already - as long as the checkbox is checked, the AI window will have the "buys/sells" area disabled. Then you set the NPC's AI-Settings to buy/sell what you intend to. (An Alchemist isn't very likely to buy or sell armor...) You can also choose one of the predefined merchant-classes instead.

You also need to give the NPC an AI Package with "Offers Services" checked. Usually you can simply pick the predefined package "aaaServicesEditorLocLockAtEnd".

===Selling===
Once you've set the AI, the NPC will sell everything he '''owns''' and hasn't equipped yet.

An Object's ownership is inherited by the container or cell it is in. So a merchant will sell:
* Items in his ''inventory'' that aren't equipped.
* Items in the current cell when he ''owns'' the ''items''.
* Items in the current cell when he ''owns'' the ''cell'', and the items don't belong to someone else.
* Items from any ''container'' he ''owns'' that is in the current cell.
* Items from any ''container'' in the current cell when he ''owns'' the ''cell'' and the container doesn't belong to someone else.
* Items in the container set as Merchant’s Container in the NPC Reference window (see Notes below). This container may be anywhere (handy for traveler merchants).

Wares and containers have to be enabled to appear in the selling list.

===Buying===
Everything a NPC '''buys''' will either go to the "Merchant Container" you've associated in the NPC's reference-window, or to his inventory when he doesn't have a container. (Which will cause them to equip good stuff like in Morrowind) 

===Private stuff===
There are two ways to prevent a npc from selling stuff (Like the family-shield on the wall of an armorer's shop):
# Don't set the cell to be owned by the NPC (i.e. set cell ownership to a faction that NPC belongs to), and give him explicit ownership for each object he should sell.
# Choose another owner for the objects that the NPC doesn't want to sell. (e.g. the Faction "Generic Owner")

===Fences===
To have the merchant buy stolen goods, you need to set his "Responsibility" AI-setting to 30 or lower.

===Notes===
*To set up cell-ownership go to the right-click on the cell in the "cell"-window, choose Edit...Interior Data.
*To associate a container with a merchant, double click the container in the render window, then adjust the settings on the ownership tab appropriately.  Then, edit your merchant in the render window by double clicking him or her, and adjust the settings on the Merchant Container tab appropriately.  Note that the container should be marked as a persistant reference, and is generally kept outside of the playable area, so that players cannot steal back stuff they just sold to the merchant.  You can also, instead of double clicking on the merchant and container in the render window, find them in the Objects list of the Cell View window, then right click them, and select edit.
