SSE Undeath: Nif Crashes / Compatibility Woes

[Antioch08]

Hey guys,

 

Some time ago I made Undeath, a modification that lets you transform into a Lich using an altered Dragon Priest model ingame.

I'm in the process of trying to bring it to SSE but I've hit a major snag in the process and need to find out if anybody knows whats going on. The problem is this:

 

Changes to the new NIF files now mean that the dragonpriest skeleton.nif (or any traditionally non-playable skeleton) will crash the game when 'readying' weapons. This crash only seems to occur if its the players race - NPCs play all their animations just fine. The problem may be related to camera bones / controllers but so far all my experiments in this have failed to reveal anything conclusive at all, and the total lack of any crash reports from Skyrim make tracking the exact issue down a nightmare.

 

If anybody's had experience with this issue before or think they know what could be causing it based on the new NIF format pls halp.

I wish I knew how to help you as I really enjoyed Undeath. If I find something out, I'll let you know. How did you manage the transformation from player character to creature? I know the Fallout 4 community was talking about making a werewolf and I wanted to see Undeath in Fallout 4 as well.

I was able to make the dragonpriest race playable in vanilla Skyrim the first time round by following this tutorial: http://hubpages.com/games-hobbies/How-to-Play-as-Monsters-In-Skyrim

 

The only thing that was needed for it to work correctly was the addition of a 3rd Person Camera bone (similar to the one from the Vampire Lord or Werewolf form) added to a creature race, but unfortunately it seems like something else is needed now with the new nifs to be player-compatible.

Unsure if you've already done the same thing, but when I converted meshes over, I used this:

Haven't had any issues, including skinned meshes. Not sure if the same would work for a skeleton nif, but worth a shot.

Bump, any nif experts about? Yes I've already run this through the optimizer but to no avail. This is a problem purely related to the player being the dragonpriest (or any monster race) for that matter and drawing weapons.

Hiya guys. I'm not sure if this will be of any help, but I too was working on making the Dragon Priest playable(in my case a placeholder until later) and I too ran into this issue of crashes when readying my hands.

I figured I'd take a look on the internet and found this thread, but not much else. Eventually I figured I'd take a look at the Vampire Lord so I could see how the skeleton.nif was set up, and a major difference I saw was under the first NiNode, titled NPC.
Highlighting that NiNode will show the info in the lower left panel, which has a Flags section. Between the Dragon Priest and Vampire Lord, the numbers I saw were radically different, so I figured I'd look at the flags to see what was different.
Turns out, there was only one extra flag in the Dragon Priest skeleton.nif, which was a No Anim Sync flag or some such. Ticked that off, saved and ran the game, transformed into a Dragon Priest, and voila, it seems not to crash anymore when I load from a save where I'm already transformed. From that point, it continues to allow me to transform and ready my hands as usual.

So tl;dr, untick the all No Anim Sync flag in the Block Details for the first NiNode of the Dragon Priest skeleton.nif, there are several

I'm still looking for what's causing the initial problem. But this is progress I think.
Of course, it might only work on my PC, as these things tend to be irksome as possible.

EDIT: scratch that, it seems I just happened to get it to work on that specific save. I still cannot for the life of me figure out what the hell is wrong with this mesh/animation.
