Honestly, I don't even know.
The only thing I've managed to learn is that apparently the NIFViewer doesn't actually play the animations? Nobody told me that. At least, it doesn't play the ones exported from Max. I'd been checking the exported models in NIFViewer to see if they worked, and none of them did. Occasionally I'd check them in the game too, and they still didn't work, so I had no reason to doubt the NIFViewer. However, on a total whim, I decided to bring one of the non-working NIFs into the game, and it actually worked. So clearly on some models, NIFViewer is lying about what does and doesn't work.
edit-
Which images? To which tutorial? This one or the one I posted in the Tut forum, or the uploaded one?

Sezereth: Just one quick question about these attachable heads/armourparts you want from me. Do I need to do anything special with them when I export them, to let the game know they're attachable to other units? Or do I just export ordinary, static meshes? For example, let's say I make the Scout with no dress and a full bone structure, and I make 3 heads and 5 armour parts. Do I just export them all, individually, into 9 separate static NIFs?
gratulations to exporting your model

ok, first, the nifr viewer does only play animations like a rotating rotor of a plane

no single other animation that is writen in a kfm file...
second, the unit on the picture i posted, i dont draw every single line of a unit with a brush, i used the texture of the original viking as the base (to know where his proportions are), the rest is done by layers, filters and a huge bunch of highlighting, darkening and some real drawing with a brush plus a big amount of that funny finger dragging tool

but i didnt use any texture of another model !
Sometimes, for example to create a shirt, i copy the upperbodytexture of the unit, recolour it, use some filter and then draw and drag and highlight and stuff above it, but thats not different to create a new area, color it and do the same (except that you already have some life in the layer ehre the filters can apply, but you can easily draw that yourself too). so i can do a new texture on a blank UV map, if you ment that

(and i started some time ago to not use anything else than what comes from photoshop or from firaxis for textures). i dont even use templates (images from figures), it just pops up in my head and then it is a trial and error...
third: about those meshes, best would be you ask whiterabbit about that... with weapons, it is very easy, they can be mesh only. and with heads, perhaps it is good to have them a BIP Head in, i think then the head actually can be attached and is then part of the model instead of a seperate mesh, but dont know if this works, cause ive only seen this with actual heads from vanilla models (ripped of ones by rabbit and chalid)
