MP Weapon skins could be cool

[Jason of the Argonauts]

Right now in factions like the Aserai and Empire you can adorn your character in shimmering golden armor by grinding loot, however your weapons are still rather plain looking.

The Singleplayer mode already has the equivalent models for weapons with gold inlays and ornate designs with the "Decorated" weapons (Decorated Arming Sword, Decorated Broadsword, Decorated Fullered Sword, Decorated Kaskara, Decorated Long Scimitar, Decorated Long Warsword, Decorated Saber, Decorated Scimitar with Wide Grip, Decorated Short Spatha).
Along with some other miscellaneous weapons (Arming Sword with Circle, Crescent Guarded Arming Sword, Gold Bound Short Warsword, Gold Engraved Arming Sword, Lion Imprinted Saber, Spatha Blade with Ring Pommel, Thamaskene Steel Spatha) and a myriad of different golden/jeweled/etc options you can use when smithing weapons.

So it would be nice to spend loot on weapon cosmetics in addition to armors. A lot of people already have several thousand loot saved up, so it would give them an excuse to burn through it if they can buy weapons as well.

could be cool.
could also be cool to have a working game first.

Weapon skins wouldn't really work the way I thought it would.
After making an overhaul mod for multiplayer (Mount and Blade II: Warband), I've learned how weapons work. You can't really manually set damages or length, so the meshes of the new weapons would need to be identical to the ones they replace.

The only real solution to adding weapon skins would be to just have new Textures, luckily nearly every weapon uses weapon_crafting as their material/texture, so you'd only need to make one new texture to have weapon skins.
