WoW Model Viewer is a crazy useful tool for machinimists or just anyone out there (like Zach) looking to enjoy the art of Warcraft outside of the game itself. The only problem with the app is that it hasn't updated since way before Wrath's release, but the code monkeys over there have finally rectified that: they've dropped release version 0.6.0.2, which we're told is compatible with the models in Wrath of the Lich King.
Mostly compatible, anyway -- we're told that lots of the new animations aren't working yet, and there are quite a few bugs still poking around. And there's more trouble -- the program's admin has reported that the site could use a new host, since the last admin had some troubles with the hosting provider. Surely there's someone out there who can help -- lots of people use the program (and of course it's spawned countless terrific machinima movies that we've all enjoyed).
Hopefully Model Viewer will find its way back on track -- the program has really jump started the world of machinima, and it would be a shame to see it fall into disrepair due to lack of support.
