Here I was thinking this would be a thread asking for the ability to obtain items to add glow effects onto weapons that did not have a glow effect.

In general trying to customize the base model itself is going to be nothing but problems, given that most weapon component elements wont get seen anyways and what most people care about are animations and glow effects rather then the base look of the weapon itself.

A basic longsword looks cooler with a eastern flame dragon snaking up its length and its very noticeable. No one will notice that the pommel (the bit below your hand) is from an ironworks magitek sword.
