Hm... took a look at nordic longswords.
Glass longsword could use blade retexture(that repeating stripe needs to go).
I think all of the nordic swords could use some highligts at hilt (iron and ebony are perfect examples, by "highlights" i mean different colours). Well, dwemer is great without it, but, hey, it's dwemer.
Orichalcum texture, imo, should be nonuniform and much more cruder(?).
And, personally, I don't like silver\glass combo, but it's just me, I guess.
All statements above are solely my opinions. You can ignore them, if you wish)
Glass probably isn't going to change again. It's been changed a half of a dozen times up until this point and the current texture was chosen by the group. Not unless you have a better idea?
The weapons that don't use precious metals don't use precious metals for a reason. Unless you have better ideas. Dwemer is essentially never used with any other metal on the same object. Steel is supposed to represent strength & functionality, adding a precious metal would take away from that. Besides, I think most players (including myself) would be annoyed with needing to use gold or silver to forge a sword out of steel. Besides, if steel was paired with a precious metal it would be less different than the other metals which are paired.
Orichalcum should be cruder? How & Why? It isn't paired with a precious metal, like steel, in order to make it look more basic & functional.
