Minecraft renders: Azeroth, the PC Gamer server, and how to make your own
8. Click the 3D cube that's in the middle of the screen by default. Press Delete on your keyboard, and remove it. Then press space, and in the Find window that appears, type 'import'. At the top, you'll see Import OBJ. Click that, and browse to your C:\\renders\\mcobj folder. Here, you should find the world1.obj you created. Open it and wait; this might take a little while, depending on how much memory your computer has.
9. Boom, you should now have a 3D model of your Minecraft world open in Blender. Now you need to position the camera; there's one already created by default. Press '0' on the numpad to select it, then when your 3D view has snapped to the Camera's position, press Shift+F. This enters Fly mode, and lets you control the cameras position by moving the mouse and rolling the scroll wheel. It's a little fiddly, but for a video example of it in action, try this video tutorial.
