I've honestly never used a staff once, do they just disappear when you sheath them?
Your second melee weapon does this too. If you have two swords, only your right handed one is sheathed, the other one simply disappears. I would love to see integration for all these things to actually remain on your person.
Yep, that bothers me too about the second melee weapon. So let me go off my own topic and mention that too....
Think back to Oblivion and how you might use a sword, shield, bow and arrows. If your sword was equipped, you wouldn't see the bow and vice versa. Compare that to Mount&Blade where you could simultaneously see a sword at the hip, a shield on the back, a bow on the back and a quiver. It was always a nice touch I thought. With Skyrim, instead of improving on third person weapon display, it becomes even more disappointing when you consider we can wield two melee weapons at once but only see the main one. I would have thought that after all these years someone might've made a mod for that, but I imagine the scripting is kind of tricky because what kind of conditions would you be looking for? The Oblivion engine sees a weapon as either equipped or not. It can't tell what you'd LIKE to see sheathed---only what the active weapon is, and whether it's ready or not.
Forgive me because I know nothing about scripting, but is it possible that Skyrim provdides a new tool for scripters to call up a condition, namely whether an item is included in your list of favorites? Would it therefore be possible to make it so a weapon assigned to your right hand in the favorites is sheathed to the hip or the back, a weapon assigned to your left hand is sheathed to the left hip, and any and all appear simultaneously?
You know I had a glitch once. I used the console command showracemenu and might've been drawing a weapon when I typed it. I don't remember exactly how it happened. Anyway, when I closed the console and went back into third person I noticed it was displaying a mace on my right hip and a sword on my left. I took out the mace and it worked, but it also still showed the mace on my hip---meaning I had two maces, a glitch within a glitch.

Point is, it looked amazing and, well, more than amazing, it simply looked
the way it should.
Does anyone have any thoughts on any of this, or on my original staff question?
EDIT:
I
think I see your point. The staffs are one handed, and the game is hard-coded to show one-handers equipped at the hip. Making staffs "appear" when sheathed would actually show them at your side and look ridiculous. So we would need to somehow tell the one-handed staff to appear on the back like a two-handed weapon. Now it gets tricky, I assume, and maybe more work than it's worth.
