Does something control the ability to dismember on a per-weapon basis?

[HomicidalGrouse]

I know that there are at least two ways to edit the ability for enemies to get dismembered.

 

There are the bodypartobject settings that affect global chances for for severing/exploding specific limbs for specific actor types (humans, deathclaws, mirelurks, etc).

 

There are also On-Hit settings per weapon that can be set to either use the default formula, only allow exploding limbs, only allow severing limbs, and allowing neither. This also works for weapon mods.

 

However, there seems to be another variable that I can't track down. If you compare the ability to dismember limbs between different weapons, the chances or even ability to do it at all seems to be different. For instance, using a standard 10mm pistol, it would seem as though you can't sever/explode limbs but you can explode heads?

 

I loaded up the game and using a standard pistol, I was able to blow off the head of a deceased raider within 2 shots. Sometimes less. Meanwhile, shooting them in the legs and arms had no real effect. Blood spurted, the bodies moved from the force, but no legs and arms exploding or being severed as you see with the head.

 

Alternatively, a standard bladed weapon seems to be able to dismember corpses just fine. Just a swing or two and you're left with a bunch of pieces ready for Dexter's garbage bags.

 

So am I crazy? Is the ability for weapons to dismember limbs only controlled by the two variables mentioned above, or is there something I'm missing here?

 

I'm asking because I would like to edit the dismemberment capabilities of certain weapons. For instance, I would like to make it so that if you're using the 10mm pistol, you can't blow off limbs or heads. Meanwhile, I would like to make it so that the .44 can only blow off heads. Furthermore, looking at weapons with different calibers, I would like to make it so that for instance .38 caliber pipe weapons can't blow off limbs, but if you mod the .50 cal receiver onto it, it can.

 

With my current knowledge of the CK, I can easily toggle the ability to sever/explode limbs in general, but I can't seem to change those settings independently on a per-weapon per-limb basis, despite the fact that it would seem as though there IS indeed some way to do that based on the behavior of different weapons.

 

I'm scratching my head a bit here. My only guess is that it's controlled with a script somewhere.
