Configuring a server for drought or ice-age worlds

  • Suppose I wanted to run a server with extra challenge. Is there a way to set up the world so that it starts with extreme cold or desertification? Would that be a mod or a change to the server settings?

  • I second this greatly. After trying everything from modifying layers and attempting to change the basic ground block under worldgeneration I've found now way to modify biomes for world gen. I'd love to make a desert world for the challenge factor.
