Tangential to this cool project, Hytale has an amazing modder experience and toolset built into the game. Everything is JSON driven, with hot reload, so we can build tooling in any language (without needing to name said language, lol to that thread here, ahem, I'm using CUE, ahem). They have flags to dump the JSONschema for everything, including mods, as well.

More related, Worldgen v2 is pretty amazing compared to Minecraft. What is the basis for the Worldgen in this project? Not too different from a 3d voxel game? I'm pretty new to it and have a general curiosity still.
