There must be some way to do it. After all, there are the pre-rendered faces on guys in the loading screens.

I need to make a mask that looks like a face. Ideas?

Not sure if this is helpful, but when you export facegen data it literally just makes a nif. Not sure if it's formatted or 'right' or anything though.

Huh. Someone else was asking about making a load screen mesh from an NPC and I didn't think it would be possible without jumping through hoops. Did not even think of the facegen data. It looks to be a perfectly valid nif. Thanks Alexander!

How you export facegen data?

And where u get from : npc creation kit or ingame race menu?

In the object window select the 'Actor' catagory, then highlight (select) your actor, and hit Control + F4. Say yes, and it will export the facegen data and related texture to "Meshes (Or Textures)\Actors\Character\FaceGenData\FaceGeom(FaceTint for textures)\MyMod.Esp\"

That will give you a nif and the texture for it, that you should in theory be able to use like any other nif from the game.

But is not possible from main character?
Also the other way around not possible as well?
