Recently we have finished the project Slovenia from blocks, where we presented a system for photorealistic rendering Slovenian landscape with 1 m sized blocks. Just a while ago two of our students contacted us if they could connect to our data provider for generating Slovenia Minecraft world. While the world of Slovenia is still generating the city of Ljubljana has mostly finished generating and can host users in spectator mode.
You can find out more about the project and on how to dive into the blocky world of Slovenia in Minecraft here.
