Supported Minecraft Worlds

Any Minecraft world that was saved by Minecraft version 1.2 or later is supported. If you load a world in Chunky and it appears to have no chunks, that is probably because it is saved in an older world format. You can convert your world automatically if you use the latest Minecraft version to open the world.

Some block types from weekly snapshots have not been implemented yet. They appear as purple question marks in Chunky.

Blocks that are added to the game by mods (such as Feed The Beast) are not supported currently.
