I know it's such a little thing, but the invisible bowstrings have always bothered me and I finally decided to do something about it (Just in time for the new Arcane Archers). While I was looking through Bioware's bow models I came across some extra unused models and I have added them to this hak as well. There are now twice as many long bows and short bows and they have all been modified with animated bowstrings. In addition, Mark Valentine 'h20rat' has graciously provided a Goblin Bow with a new texture, available only in this hak at no extra charge. :)
There is a demo module included which displays all of the available bow models and colors. Be sure to check the readme file for details and known issues.
