📋 About This Mod
Engine-level fix for the annoying Essential/Protected NPC abnormal decapitation issue.
Ever modded Ada with the Reaper Head and watched her attack settlement settlers, only to find some of them walking around with their heads already on the ground? Heads detached, but the NPCs are very much alive: That's the "dismember before death".
There is no existing solution that addresses the root cause. Script‑based patches are incomplete . They only cover specific scripts, break compatibility, and miss new mods. I’ve taken an engine‑level approach, hooking every dismemberment call at the Havok endpoint (bhkWorld::SetDismemberedLimb).
Features
-
[]Hooks bhkWorld::SetDismemberedLimb. The engine-level endpoint every dismemberment call passes through, regardless of source[/]
[]Two-level flag check (runtime boolFlags + base record) to catch both setessential and setprotected correctly[/]
[]Essential NPCs → heads stay on, period. Protected NPCs → heads stay on while alive, come off only after real death[/]
[]14-byte absolute JMP hook — safe to stack with other F4SE plugins[/]
[]Written in C++, with almost zero runtime overhead.[/]
Install with your mod manager. That's it.
Any time. No cleanup needed.
