One Chunk Blocks

One Chunk Blocks turns world generation into a chunk-by-chunk block mosaic.

After terrain and features are generated, each chunk is assigned one deterministic block from a large palette. Most solid blocks inside that chunk are then replaced with that chosen block, so one chunk may become stone, another may become quartz, another may become obsidian, copper, terracotta, wood, planks, or many other full blocks.

Gameplay

This mod creates a chaotic and unusual survival world where every new chunk can look completely different from the previous one. It is meant for challenge runs, strange exploration, and worlds that feel unpredictable without fully breaking progression.

Notes

This mod affects newly generated chunks. Existing terrain that was already generated before installing the mod will not be changed.
