[LE] Problems with adding new animations

[ProfJack]

I've made a killmove-like animation, and since I don't have paired animation rig in Blender I exported them as two seperated animations: one for the attacker, one for the victim. Using FNIS, I imported them as two basic idles (fiore01_killer and fiore01_victim):

b -a,Tkillmovestart/0.0,Tweaponswing/0.4,Thitframe/0.583333,TSoundPlay.NPCKillStabIn/0.583333,Tkillmoveend/1.498 fiore01_killer fiore01_killer.hkx
b -a,Tkillmovestart/0.0,Tkillmoveend/-0.002,Tkillactor/-0.001 fiore01_victim fiore01_victim.hkx

Then I tested them by calling NotifyAnimationGraph in SKSE (I've heard that they're equivalent to Papyrus' Debug.SendAnimationEvent, so I guess my SKSE coding shouldn't be a problem?) whenever one actor hits another. It kinda worked and the animations are playing. However, there are issues:

1. For the attacker animation, it all goes well until the animation ends and then the actor stays in a A-pose state and cannot attack. In FNIS documentation it says it'll trigger IdleForceDefaultState afterwards unless with option -Tn, but adding that didn't help.
2. For the victim animation, at first it didn't even play and the victim just died instantly. It turns out that all events just fired at once at the start of the animation.
3. After I removed the killactor event, the victim animation could play but often times it was interrupted by staggering. I tried calling event staggerStop before the animation but that seemed no effect.

I'm feeling that I have to venture into modding behavior files and Nemesis which I'm not really hoping to do, as I thought I was just adding some animations and call them with code, like those flashy moves by elysees, and not messing with player controls. But Anyways, I still went searching for guide and came across this post https://forums.nexusmods.com/index.php?/topic/9329348-fallout-4-havok-guide/ which is really helpful and gave me some ideas about hkx formats. Then again when I tried to understand how to make my own behavior mods within the undocumented Nemesis I felt mostly clueless. Like, how do I structure my files? How do I generate the gigantic amount of files required like other mods that utilize Nemesis do? How do I use the templates provided that look like what I need? I'm not bothering the author since they states that questions shall be posted in public first.

 

So all I want to ask is:

1. What are the causes of the issues I encountered?
2. Are there workaround solutions to the problems I encountered that don't require Nemesis?
3. If it has to be Nemesis, how do I even begin and is there any example?

Thanks and pardon my English if I didn't express myself clear enough.
