ChunkDebug Mod (1.21.7, 1.20.1) is a comprehensive debugging tool tailored for Minecraft players, mod developers, and technical builders who want to gain deeper insights into how chunks load and behave in real time. This mod provides a detailed, interactive interface that displays all currently loaded chunks, complete with their generation status, ticket types, and spatial data.
