I need an infinite source of unique looking npcs for my mod. Naturally i thought i would just tick the "random" checkbox in facegen parameters in the creation kit or something but ohmygosh, there is no such thing! I inspected how the leveled character and character templates work and turns out every single face in skyrim is hand made :/ that is crazy. I'm looking for any kind of angle i can to not have to create hundreds of faces by hand because the way they appear in my mod, repetition would be noticable. If there is any known way to generate faces, please let me know.

And no one would care because we're all used to it from the vanilla game, oblivion and morrowind. There is only so much variation until it all looks the same after awhile.

Now for face morphing, I know you can't generate those at run time. I don't know about just changing head meshes, skin tint etc.

http://www.nexusmods.com/skyrim/mods/49373/? has an NPC generator, but when I try to use it, it errors out after making a single NPC. Maybe you'll have better luck.
