[MDL ED] Entire World

[NaxEla]

I'm pretty sure it's possible to convert a minecraft world into a single model. I know there are some Left4Dead 2 custom maps that did that, and I'm pretty sure all they just created the map in minecraft, then converted it into a recognizable file that they could use to make a model out of it. Worst case scenario, you'll need to create a bunch of different models which will all be cubes (just create a new file in Blender and you wont even need to make the cube!). Then just apply a texture to them.
