I've been trying to turn a normal bow into a bound bow, but after the spell finishes casting, the sound stops abruptly... So I'd guess the NIF file has information about the sounds the bound bow makes when it's summoned from the oblivion plane.

Now... How would I go on about having that on another bow model? I already have everything set up. (This being the spell, book, magic effect, magic FX, and the object effect.)

The bow mesh comes from rerout's http://www.nexusmods.com/skyrim/mods/37186/? mod, if you're interested.
