This is the second image of a Minecraft world exported to Blender. It showcases the raytracing volumetric rendering which creates an atmosphere which cannot be achieved in real time. The second image is a 20% size test render, but which somehow accidentally turned out a lot better than the final version.

Scenery of the Minecraft Nether dimension. It is mostly like an ingame screenshot, except that the laval is translucent so you can see its depth, and the glowstone actually glows. The lava lake is covered in a layer of thin white smog or mist. Same image as the first, except a quarter the resolution and the visual effects are a lot stronger. The mist is denser and filled with glowing particles (which are more likely rendering artifacts than volunatry), and the glowstone glows even stronger.
