Model in Minecraft, render with Blender ;-)

With this addon, Minecraft saves can be loaded straight into Blender 2.6. I made this to address the popular trend in the Minecraft community where many people are exporting save data to render out in VRay, Octane, etc with limited surface data. I've now tried Mineblend exports with Cycles and found it was pretty awesome by default.
I hope somebody finds this useful.
