How do I add weapon mods to a weapon in FO4Edit?

[falloutkid12]

Short ver:

Let's say I wanted to add recievers to the minigun, a weapon that doesn't have recievers by default. How would I add a "Reciever" category to the minigun, and how would I add several recievers to that category?

 

 

 

Long ver:

I've tried dissecting other mods that add brand new weapons and weapon mods, but I still have no clue how they set mod categories(ie. Barrel Mods, Recievers, Magazines, etc.) on their weapons and the OMODs that show up for each category. I know the process involves using keywords in some way(like ap_mod_barrel, ma_Xgun, etc.), but have no idea how keywords work. So I guess the real question is, how do keywords work, and how would I go about setting up a new category for attaching mods to weapons,(and armor too, i guess.), as well as assigning OMODs to that category?

1. Add the mod slot keyword (ap_gun_receiver [KYWD:00024004] in this case) to the APPR keywords in the WEAP.

Copy existing mod into your .esp, and add it into the part combinations list (OBTE). Notice the copied mod must not have any submod keywords assigned to it in the DATA Keywords, just the keyword that defines the type of the mod (for some reason they cannot be completely removed so you'll need a mod without them). Most receivers have barrels, magazines etc as subkeywords, but since these are already in the WEAP of minigun, you don't want the receiver to have them as well.

Change the mod keyword into ap_gun_receiver so that it's flagged as receiver.

Change the MNAM keyword to the one used by the gun which will use the mod (ma_Minigun [KYWD:00123688] in case of minigun).

Remove the Model used by the mod to prevent the mod from having visual effect.

Create constructible object form for the mod so that it can be crafted (optionally make misc mod item for the mod if you want it to be storeable).

Add and adjust the effects of the mod.

Duplicate the created mod and make constructible object form for it to create new receivers.
