Balmora Expansion lacks meshes for the silver armor gauntlets in first person view, and I'd like to put something there - but I have no idea where to locate the first person hand meshes.

Same place as the usual hand meshes. Make a body part identical to the third-person hands, but append ".1st" to the end of the ID and set it to use the first-person hand mesh.

Just so I'm clear on this:

I can find the third-person meshes for the gauntlets, copy them and name the copies *.1st.nif and they should work?

It worked. Thanks.

Well... no.

You're supposed to use different meshes or the fingers will be funny, or so I've heard (the voices aren't quite clear on such things <_< ).

But the body part records in game have to have the same ID, except that the first-person has .1st at the end.

So you have the meshes: bb\handm_o.nif and bb\handm_o.1st.nif and the body parts bb_handm_o (linked to the first mesh) and bb_handm_o.1st (linked to the second).

The problem is that there is no first person mesh for the silver gauntlets from the Breton Night in Balmora Expansion and I can't make meshes for Morrowind.

I copied the existing third person meshes and it works okay so far - I haven't noticed any finger oddities. If I do, I'll copy another 1st person mesh and give it the silver texture.
