If you are experiencing problems with the AddOn, please submit a ticket here.
UPDATE: This addon has been updated to with with Mists of Pandaria. I also fixed some code that was causing UI taint. It should work better than ever.
Creates player and target portraits from 3D models using some modified default UI frame graphics that blend well with the default Blizzard UI elements. You can use it standalone, with completely round frames, or you can use it to cover the default 2D portraits on the default frames by moving the frames around with the mouse.
There is also a config option to use PitBull4's player and target frames as the parents of the 3D portraits. This makes it quite easy to make PitBull look more like the default unit frames.
There are a few other configuration options to check out as well. They are in Interface/AddOns from your WoW main menu.
The latest beta version contains some nice textures you can use with kgPanels and PitBull4 as you see in the pictures. They're in the Textures directory. I'd suggest adding them with SharedMedia and then creating kgPanels parented and anchored to the PitBull4 frames. That's what I'm doing with them at the moment.
I've also added functionality to display some of the Blizzard vehicle frame graphics when switching into a vehicle, also changing the model.
Another nifty new feature is that the player frame shows a small graphic when the player has a debuff that can be dispelled. This feature isn't totally complete, and will need to be fixed for Cataclysm, since the dispel classes are changing.
If you're looking for a simpler, more customizable 3D portrait/unit frame addon without all the fancy artwork and functionality, I've created one. You can find it right here.
NOTE: I'm no longer packaging alpha builds, since I like to do lots of commits. (Working on different machines...) I'll try to keep the betas reasonably stable.
