So one the of the mods I am working on requires dead npcs. I was wondering if there was a way to make it so that they would lie in the position given to those who are put to rest, as apposed to how it normally works out that they just fell that way. If it is possible, has anyone does this before? And what would it require? I am thinking it might be a script, but I am still very new to scripting.

Set the NPC as "Corpse Persists" and they don't do the death animation upon entering the cell. They will just be "dead" 100% of the time.

What I want is how the lay on ground, or in this case table. Dead bodies always look they just fell to the ground in that position after they died, but I want it to appear that they have been moved and are laying in a position that suit that, such as with the arm at their sides and their legs straight. It would look weird for them to have been moved to a table, and they look like they collapsed there.

p.s. Sorry if I didn't make that clear in my original post.

There is no way to control limbs/animations as you want.
You would have to edit the body in something like Blender, either as a static mesh or as an animated body.

Pity... Aw well, seeing as I have mo knowledge of Blender and the like I'll figure out how to work with them as is.

If you'd like I could take a look at it for you. If you're interested send me a PM with details on what exactly you're wanting and tomorrow I'll see if it's something I can figure out.
